Proto:Pokémon Gold and Silver/Spaceworld 1997 Demo/Pokémon

This is a sub-page of Proto:Pokémon Gold and Silver/Spaceworld 1997 Demo.

Despite only being a demo, this build of the game contains data for 251 Pokémon: the returning original 151 as well as 100 newcomers. While only a handful are obtainable through the demo, all of them have front and back sprites, names, typing, and the like. For the sake of accuracy, the "Final" sprites shown here are from the game's original Japanese release. A handful of sprites underwent further changes during the localization process prior to the game's international release, the full details of which can be seen here.

Pokédex

The final games have a handful of Pokémon menu sprites changed in relation to this demo, including some newly designed ones not yet implemented as of this build. Said missing menu icons are marked with an asterisk (*) in the following tables.

Original 151

All of the original 151 Pokémon received brand new sprites, with both front and back sprites being completely original. Interestingly, many of the front sprites come from the Japanese release of Pokémon Blue. This is due to both Blue and Gold and Silver being developed side by side with Blue being completed first and ultimately making use of these sprites first. Oddly enough, the back sprites seen here are exclusive to this build, as for some reason Blue reused the original Generation I sprites, and so did Yellow, despite itself receiving a set of brand new front sprites. These back sprites already follow the same design philosophy as the final Gold and Silver ones, with them being drawn in full resolution instead of being stored at half size like in Generation I.

Another thing worth noting when it comes to the relationship between this build of the games and Pokémon Blue is that the former shares the latter's changes made to Nidoqueen and Geodude's weights, as well as Porygon's Pokémon category. The category change and Nidoqueen's corrected weight would go on to be featured in the final versions of Gold and Silver, whereas Geodude's decreased weight was reverted in Japan starting with Yellow in 1998.

Dex #	English Name	Demo			Final (JP)			Name	Notes
1	Bulbasaur							フシギダネ Fushigidane	Front sprite is similar to the final, with the legs later being adjusted. Interestingly, the back sprite shows Bulbasaur standing on its hind legs, which, while canonically possible for it to do, has never been seen explicitly.

109	Koffing							ドガース Dogāsu	Sprites were redrawn for the final; poses are the same.
110	Weezing							マタドガス Matadogasu	Features yet another unique inconsistent head arrangement. The back sprite seems to reflect a different design entirely, with the middle head facing the back, and the smaller gas chamber actually being a Koffing. This is interesting, as Weezing's Generation IV and V Pokédex descriptions mention the existence of "triplets", meaning that this concept never seen physically before or since was already thought of as of 1997.

112	Rhydon							サイドン Saidon	Uses its Blue front sprite.

119	Seaking							アズマオウ Azumaō	Back sprite interestingly has a spiraling horn.
120	Staryu							ヒトデマン Hitodeman	Uses its Blue front sprite. Back sprite faces a different way, and lacks the golden ring loop on its left leg. Most likely an error on the designer's part.

136	Flareon							ブースター Booster	Back sprite has ears engulfed in white fur.
137	Porygon							ポリゴン Porygon	Front sprite is almost identical to the final with a few shading differences. Is already known as the "Virtual Pokémon", a species name change that would ultimately appear first in the original Japanese release of Blue.
138	Omanyte							オムナイト Omanyte	Uses its Blue front sprite. Back sprite has slanted pupils and a different shell design.
139	Omastar							オムスター Omastar	Uses its Blue front sprite. Back sprite has spikes reaching further down the shell.
140	Kabuto							カブト Kabuto	Uses its Blue front sprite. Back sprite has a different design for the extremity of its shell, which can also be seen in the front sprite.
141	Kabutops							カブトプス Kabutops	Uses its Blue front sprite. Back sprite is based on said front sprite, as seen by the pose. Back sprite interestingly lacks the head horn has a head cavity in its place.

147	Dratini							ミニリュウ Miniryuu	Front sprite was redrawn for the final; pose is the same. Back sprite is explicitly based on its Blue front sprite, as seen by its striped stomach.

150	Mewtwo							ミュウツー Mewtwo	Uses its Blue front sprite. Back sprite has its tube reach further down, and the shoulder design is also different. Back sprite is explicitly based on said front sprite, as seen by its pose. Despite the front sprite receiving a new pose, the final back sprite actually appears to be based on this early one.
151	Mew							ミュウ Mew	Front sprite bears a resemblance to early Red and Green Mew artwork This sprite was also used for the Spaceworld 1997 Mew giveaway, as can be seen in this contemporary report at the 32:23 mark.

Demo 152-251

The 100 new Pokémon introduced in this prototype, of which only 60 were officially released as part of Generation II, with 29 of those released Pokémon undergoing anything from minor to major design revisions before the final releases. Also note that while somewhat organized, the order in which these Pokémon appear in likely reflects some sort of internal index. The final incarnation of these Pokémon (if known) will be provided for comparison.

Demo #	Final #	English Name	Demo			Final (JP)			Demo Name	Final Name	Typing	Notes
152	152	Chikorita							ハッパ Happa From 葉っぱ happa (leaf).	チコリータ Chikorita	Grass	Base stage Grass starter. Sprites are almost identical to final, with some minor touch-ups to the leaf, mouth, and overall shading.
153	153	Bayleef							ハナモグラ Hanamogura From 花 hana (flower) and 土竜 mogura (mole). In Japan, moles are called "earth dragons", tying in closer to Meganium.	ベイリーフ Bayleef	Grass	First stage Grass starter. Has a completely different design, with it seemingly being based after the idea of a Chikorita "blossoming". This is where Meganium gets its antennae.
154	154	Meganium							ハナリュウ Hanaryuu From 花 hana (flower) and 竜 ryuu (dragon).	メガニウム Meganium	Grass	Final stage Grass starter. Sprites are almost identical to final, with some minor touch-ups to the shading. Back sprite was redrawn, and the sepals were removed. Interestingly, the flower would later be redesigned in Crystal.
155	--	--				--	--	--	ホノオグマ Honooguma From 炎 honoo (fire) and クマ kuma (bear).		Fire	Base stage Fire starter. Scrapped Pokémon based on a lion/bear cub whose ears and tail are engulfed in black flame-like fur. Ended up replaced with Cyndaquil.
156	--	--				--	--	--	ボルべアー Borubeaa From volcano and bear.		Fire	First stage Fire starter. Scrapped Pokémon based on a lion/bear whose mane and tail are made out of black flame-like fur. Ended up replaced with Quilava.
157	--	--				--	--	--	ダイナべア Dainabea From dynamite and bear.		Fire	Final stage Fire starter. Scrapped Pokémon based on a lion/bear with an ember symbol on its forehead, and black marks on its ankles. Was perhaps shelved due to its strong resemblance with Arcanine. Ended up replaced with Typhlosion.
158	--	--				--	--	--	クルス Kurusu Cruise		Water	Base stage Water starter. Scrapped Pokémon based on a plesiosaurus with two horns. Ended up replaced with Totodile.
159	--	--				--	--	--	アクア Akua Aqua		Water	First stage Water starter. Scrapped Pokémon based on a plesiosaurus with a horn and a gem on its neck similar to Dragonair. Ended up replaced with Croconaw.
160	--	--				--	--	--	アクエリア Akueria Aquarius		Water	Final stage Water starter. Scrapped Pokémon based on a plesiosaurus with three horns and a gem necklace around its neck. Ended up replaced with Feraligatr.
161	163	Hoothoot							Identical	ホーホー Hoohoo	Flying	Lacks the tuft of fur at the base of the feet, has a single black pendulum/clock-hand like tail feather instead of a brown feather duster. The face markings are also more akin to freckles, evoking the numbers circling a clock. A wavy back pattern can also be seen, with it perhaps later inspiring the chest pattern from Noctowl's final design.
162	164	Noctowl							ボーボー Booboo Corruption of Hoothoot's name.	ヨルノズク Yorunozuku	Flying	Has a design more akin to its pre-evolution, retaining the clock hand-like eyebrows and the overall body shape, though now longer, making it look like an egg timer.
163	179	Mareep							パチメエ Pachimee From パチパチ pachipachi (spark) and メエメエ meemee (bleat).	メリープ Mareep	Electric	Has a more light bulb-shaped tail orb. Interestingly, the back sprite has pink hooves not seen on the front sprite, likely from an earlier design. Is also assigned a pink palette, much like Flaaffy.
164	180	Flaaffy							Identical	モココ Mokoko	Electric	Front and back sprites are very similar to the final, aside from being redrawn. The International versions would later connect the head and neck fur together.
165	181	Ampharos							Identical	デンリュウ Denryuu	Electric	Front sprite is near-identical and was redrawn for the final games. Back sprite was remade entirely.
166	--	--				--	--	--	ミコン Mikon From 三 mi (three) and コンコン konkon (fox bark).		Water	Scrapped Vulpix pre-evolution which was originally created for Generation I. Essentially a smaller, cuter Vulpix with messier hair and only three tails. Evolves into Vulpix starting at Level 13. Typing is very likely a mistake caused by the Fire and Water types only having a one-byte difference in the code.
167	--	--				--	--	--	モンジャ Monja From もじゃもじゃ mojamoja (unkempt hair); shortened form of モンジャラ Monjara (Tangela).		Grass	Scrapped Tangela pre-evolution. Essentially a tiny Tangela with messy hair. Evolves into Tangela starting at Level 13. Interestingly uses a green palette, instead of a blue one like Tangela's.
168	--	--				--	--	--	ジャランラ Jaranra Corruption of Tangela's name.		Grass	Scrapped Tangela evolution. Essentially a massive wig with an impish grin. Evolves from Tangela starting at Level 44. Tangela would only receive an evolution, Tangrowth, in Generation IV. Interestingly uses a green palette, instead of a blue one like Tangela's.
169	226	Mantine							ハネエイ Haneei From 跳ねる haneru (jump), 羽 hane (wing), and エイ ei (ray).	マンタイン Mantine	Water/Flying	Has a slimmer, more kite-like design, with a more refined tail, no horns, wing-like gills, and an angelic front face. The back face, meanwhile, is more evil-looking, contrasting with the front face. The final design instead goes with a more standard-looking manta ray, though the eye markings on it may be a remnant from this early design. The later introduced Mantyke would end up actually featuring a face marking on its back, though this one is a smile instead of a grin.
170	211	Qwilfish							プクー Pukuu From ぷくぷく pukupuku (puffed-up) and フグ fugu (puffer fish).	ハリーセン Hariisen	Water	Evolves into Shibirefugu starting at Level 18. Front sprite matches the final except for the shading; back sprite exactly matches the final. The International versions would later remove one of the tail spots, making its motif more akin to a skull.
171	--	--				--	--	--	シビレフグ Shibirefugu From しびれ shibire (numbness) and フグ fugu (puffer fish).		Water	Scrapped Qwilfish evolution. Essentially a fat dopey-eyed sea mine-like fish with thick dull spikes, a large mouth, a lightning symbol on its forehead, power button-like eyes, and a stomach pattern as seen in its back sprite. May have inspired Whiscash from Generation III, which shares design similarities. Qwilfish's Hisuian variant in Legends Arceus would get an evolution in the form of Overqwil with a completely different, unrelated design.
172	172	Pichu							Identical	ピチュー Pichu	Electric	Has a more rounded design, with a straight tail and black feet. It's possible this early design was an attempt at reworking Pikachu's original daifuku-like design.
173	173	Cleffa							Identical	ピィ Pii	Normal	Has a different ear design, with ear holes and no dark tips. The tail is also nubby instead of curled, and the curly hair here is instead a sort of horn, accentuating Cleffa's star shape.
174	174	Igglybuff							Identical	ププリン Pupurin	Normal	Sprites are extremely similar to the final except for the touched-up face and the added tuft of hair.
175	195	Quagsire							ミズウオ Mizuuo From 水魚 mizuuo (lancetfish).	ヌオー Nuoo	Water	Has a chubbier body, no dorsal ridge, and the black body pattern is messier and extends up the tail. Has no pre-evolution.
176	177	Natu							Identical	ネイティ Neiti	Flying/Psychic	Sprites were redrawn for the final; poses are the same. Is assigned a brown palette instead of a green one.
177	178	Xatu							Identical	ネイティオ Neitio	Flying/Psychic	Front sprite is very similar to final, but was redrawn and had a black motif added onto its collarbone. Back sprite was completely reworked for the final, adding the black pattern on the shoulder, altering the position of the head feathers, and removing the "third eye" motif. Is assigned a brown palette instead of a green one.
178	--	--				--	--	--	ギョピン Gyopin From 金魚 kingyo (goldfish) and ピンピン pinpin (lively).		Water	Scrapped Goldeen pre-evolution which was originally created for Generation I. Essentially a smaller, cuter Goldeen with a spiraling horn and two small barbells. Evolves into Goldeen starting at Level 16.
179	183	Marill							Identical	マリル Marill	Water	Pose was later used for the final Silver sprite. Is pink instead of blue, has a straight tail instead of an erratic one, a larger tail orb, and slightly smaller ears which have a slightly different design. Has no evolution.
180	--	--				--	--	--	マンボー1 Manboo 1 From マンボウ manbou (ocean sunfish).		Water	A scrapped sunfish Pokémon with a small lure resembling a childish "hair swirl". Its name is clearly a placeholder, because as revealed in an interview Game Freak devs tend to use "[Basis][Evo Stage]" for Pokémon whose names haven't been finalized yet. Evolves into Ikari starting at Level 19. A sunfish Pokémon would later go on to appear in Gen V, with Alomomola.
181	--	--				--	--	--	イカリ Ikari From 碇 "ikari" (anchor) and 怒り "ikari" (rage).		Water/Steel	A scrapped shark Pokémon whose tail is an anchor on a chain. Possibly reworked from Jagg, a cut shark Pokémon from Generation I. May have inspired Sharpedo from Generation III, which shares design similarities. Evolves into Gurotesu starting at Level 38.
182	--	--				--	--	--	グロテス Gurotesu	Grotesque	Water/Steel	A scrapped Pokémon seemingly inspired by the gulper eel and possibly the viperfish, with a small head lure trademark of the anglerfish. Interestingly, this line may have actually intended to be a split one, simply using back-to-back evolutions as a placeholder. This would be supported by Manboo 1 resembling Ikari in terms of colors and spikes, and Manboo 1 resembling Gurotesu when it comes to the anglerfish inspiration. The lure aspect may have ultimately inspired Chinchou and Lanturn, while the body type may have ultimately inspired Huntail from Generation III.
183	169	Crobat							エクシング Ekushingu X-ing	クロバット Crobat	Poison/Flying	Sprites were redrawn for the final; poses are the same.
184	--	--				--	--	--	パラ Para From Parasite; shortened form of パラス Parasu (Paras).		Bug	Scrapped Paras pre-evolution. Essentially a tiny Paras living in a mushroom, likely inspired by the way some insects lay their eggs into fruits and the like. Evolves into Paras starting at Level 12.
185	167	Spinarak							コクモ Kokumo From 子 ko (child) and クモ kumo (spider).	イトマル Itomaru	Bug/Poison	Front sprite was flipped and redrawn for the final, while the back sprite was completely reworked. The design itself is pretty much identical, aside from the legs being segmented and ending in tiny claws.
186	168	Ariados							ツーへッド Tsuuheddo Two-headed	アリアドス Ariados	Bug/Poison	Has a design more akin to its pre-evolution, retaining the beady eyes, the early leg design, and the more overt face pattern on its abdomen.
187	227	Skarmory							ヨロイドリ Yoroidori From 鎧 yoroi (armor) and 鳥 tori (bird).	エアームド Eaamudo	Flying/Steel	Sprites almost match the final aside from some shading differences.
188	--	--				--	--	--	アニモン Animon From Animal/anamorph and メタモン Metamon (Ditto).		Normal	Scrapped Ditto evolution. Essentially a Ditto with a spike on its head, fangs, and a ghoulish expression. Bears some slight resemblance to the Slime enemies from Dragon Quest, which incidentally also come in a stronger metal form. Seeing how it was obtained after evolving a Ditto with a Metal Coat, this Pokémon may have influenced the Metal Powder item found in the final games.
189	--	--				--	--	--	ヒナーズ Hinaazu From ヒナ hina (chick) and chicks.		Normal/Flying	Scrapped Doduo pre-evo. Essentially a chick with three heads whose fuzz serves as a nest. Evolves into Doduo starting at Level 16.
190	192	Sunflora							サニー Sanii Sunny	キマワリ Kimawari	Grass/Psychic	Sprites are similar to the final, though with a slightly different facial expression, no lines running though its face, a consistently smooth stem instead of one which fattening up into a body, a bud whose base more symmetrical, and "realistic" roots instead of feet-like ones. Has no pre-evolution.
191	231	Phanpy							パオン Paon From パオーン paoon (elephant trumpeting).	ゴマゾウ Gomazō	Ground	Has no pads on its ears and nose, and has a longer trunk.
192	232	Donphan							Identical	ドンファン Donphan	Ground	Front sprite is nearly identical to final with some minor shading differences. Back sprite exactly matches final. Is assigned a brown palette instead of a grey one, which may have inspired its shiny palette in the final games.
193	202	Wobbuffet							ツインズ Tsuinzu Twins	ソーナンス Soonansu	Dark/Normal	Scrapped Girafarig pre-evolution. Essentially mischievous conjoined twin ghosts with ghastly spikes floating around them. This is where Girafarig gets its spikes. Evolves into Girafarig starting at Level 29. Was eventually reworked into Wobbuffet, which, while ultimately being reworked into a Psychic-type fighting dummy, funnily enough wound up keeping the Ghost menu icon in the final games.
194	203	Girafarig							Identical	キリンリキ Kirinriki	Dark/Normal	Is depicted as a giraffe with a head on each opposite side of its body, akin to something like the Pushmi-Pullyu from Dr. Dolittle. The front head has two-horns and looks docile, while the single-horned back head has an evil grin. The "evil half" was later replaced by a standard backside, though side a small mischievous Chain-Chomp like tail. Even after being redesigned, this Pokémon would keep its palindrome name and contrasting typing. The first half of the front sprite matches final.
195	235	Smeargle							ぺインター Peintaa Painter	ドーブル Dooburu	Normal	Sprites were redrawn for the final; poses are the same.
196	--	--				--	--	--	コーニャ Koonya From coin, 子 ko (child), and にゃー nyaa (meow).		Normal	Scrapped Meowth pre-evolution which was originally created for Generation I. When compared to its cut Generation I equivalent, this one has a different ear design, a short curly tail instead of a long straight one, and a forehead adorned with a 5-yen coin instead of a kōban. It's likely the three coins seen here weren't meant to actually be levitating, and that it was either a way of showing it surrounded by coins, or a way for the artist to sketch potential alternate coin designs. Evolves into Meowth starting at Level 14.
197	--	--				--	--	--	リンリン Rinrin From ring and リンリン rinrin (bell ringing).		Dark	A scrapped sleigh bell-themed cat Pokémon. Evolves into Berurun starting at Level 28. The idea of a Dark-type feline Pokémon would later be revisited in Generation V with Purrloin, though without the music theme. May have more directly inspired the Skitty line from Generation III, as seen by the tail concept.
198	--	--				--	--	--	べルルン Berurun From bell and ルンルン runrun (cheerful humming).		Dark	A scrapped bell-themed cat Pokémon. The idea of a Dark-type feline Pokémon would later be revisited in Generation V with Liepard, though without the music theme. May have more directly inspired the Skitty line from Generation III, as seen by the crescent-like head motif and tail gimmick.
199	186	Politoed							Identical	ニョロトノ Nyorotono	Water	Has a cockier facial expression, a larger body, a different mouth design, no antenna, a stomach pattern more akin to the rest of the Poliwag line, and line markings on its knees and back. The back markings were reworked into the back spots, which were removed in the International releases.
200	199	Slowking				*			Identical	ヤドキング Yadokingu	Water/Psychic	Front sprite is almost identical to the final with the biggest change being shading and a bit of its ruff being touched up. Back sprite has the Shellder visibly biting Slowking's head.
201	201	Unown							Identical	アンノーン Unown	Normal	Sprites match final. Uses the default "human" palette instead of a green one.
202	165	Ledyba							Identical	レディバ Ledyba	Bug/Flying	Sprites almost match the final, with alterations to the wings, fists, and the overall shading. Has more spots, with them also being smaller, and is assigned a green palette instead of a red one.
203	166	Ledian							ミツボシ Mitsuboshi From 三つ mitsu (three of something) and 星 hoshi (spot/star)	レディアン Ledian	Bug/Flying	Has a design more akin to its pre-evolution, retaining the eyes and overall body shape, though the round spots are now star-shaped. This likely stems from from a pun, as the word hoshi can refer to either a spot or a star. The final games would instead opt for a humanoid, Super Sentai or Tokusatsu Heroes-inspired design, though the star connection was retained, with both it and Ledyba being known as the "Five-Star Pokémon", and with the dex stating Ledian draws its strength from starlight.
204	--	--				--	--	--	プチコーン Puchikoon From petit and unicorn.		Normal	Scrapped Ponyta pre-evolution which was originally created for Generation I. Essentially a smaller, cuter Ponyta with less fire overall. Evolves into Ponyta starting at Level 20.
205	196	Espeon							Identical	エーフィ Eefi	Psychic	Sprites were redrawn for the final; poses are the same. Seemingly has two separate tails, instead of a single forked one. Is assigned a yellow palette instead of a pink one, perhaps in an attempt to better contrast with Umbreon.
206	197	Umbreon							Identical	ブラッキー Burakkii	Poison	This early typing implies that Umbreon's circular patterns may have been inspired by the blue-ringed octopus, a highly venomous species found in the oceans near Japan. Sprites were redrawn for the final; poses are the same. Despite the type change, even to this day some of Umbreon's Pokédex entries makes mention of it spraying poisonous sweat from its pores, either a reference to or a leftover from its original typing.
207	--	--				--	--	--	ターバン Taaban Turban		Water	A scrapped Pokémon resembling the shell of both Slowbro (general anatomy) and Slowking (gem). Interestingly, while never seen in-game, several of Slowbro's Pokédex entries describe it capable of reverting back to a Slowpoke if its Shellder was ever to come off. The same canonically applies to Slowking, and interestingly enough, official artwork depicting such occurrences reveal that the Shellder itself remains unchanged. Doesn't have any direct relation to either the Slowpoke or Shellder lines.
208	--	--				--	--	--	べトべビー Betobebii From ベトベター Betobetaa (Grimer) and baby.		Poison	Scrapped Grimer pre-evolution. Essentially a tiny Grimer suckling on a small shiny pacifier. Evolves into Grimer starting at Level 19.
209	223	Remoraid							Identical	テッポウオ Teppouo	Water	Remoraid, but with a more gun-like design. The idea for a fish-gun hybrid may have been taken from the Gunfish, an enemy from Pulseman, which itself may have been inspired by the archerfish. The front half of the design was kept, albeit with smaller pupils, but the back half was made more fish-like.
210	224	Octillery							Identical	オクタン Okutank	Water	Octillery, but with a more tank-like design, complete with a little helmet. The final design instead goes with a more standard-looking octopus, though it would keep a vague tank theme, with the mouth serving as the tank gun, and the tentacles evoking the treads.
211	236	Tyrogue							ゴング Gongu Gong	バルキー Barukii	Fighting	Has a similar design, though with gloves instead of hands, a helmet with bear-like ears instead of simple ear pads, no crest, and no pants. Is assigned a brown palette, much like Hitmonlee and Hitmonchan, as opposed to a faded purple one.
212	237	Hitmontop							Identical	カポエラー Kapoeraa	Fighting	Has a similar design, although literally flipped upside down. Its third leg was namely turned into a spiked tail, its legs were made slimmer, and its face was moved to where its single eye was located. Is assigned a brown palette, much like Hitmonlee and Hitmonchan, as opposed to a faded purple one.
213	--	--				--	--	--	プディ Pudi From プチ puchi (petit), poodle, and ガーディ Gaadi (Growlithe).		Fire	Scrapped Growlithe pre-evolution. Essentially a tiny pooch with a swirly tail and straight black ears. Evolves into Growlithe starting at Level 13.
214	187	Hoppip							ハネコ Haneko From 葉 ha (leaf) and 猫 neko (cat).	ハネッコ Hanekko	Grass/Flying	Has slightly thicker leaves, a more stereotypical cat face, a longer tail, and no feet. Its body is also solid black, due to palette limitation.
215	188	Skiploom							ポポネコ Poponeko From タンポポ tanpopo (dandelion) and 猫 neko (cat).	ポポッコ Popokko	Grass/Flying	Has more cat-like features, no feet, and a slightly different flower design. Its body is also solid yellow, due to palette limitation.
216	189	Jumpluff							ワタネコ Wataneko From 綿 wata (cotton) and 猫 neko (cat).	ワタッコ Watakko	Grass/Flying	Once again has more cat-like features, no feet, and no arms. Its head cotton tuft also has a more hot-air balloon-like design, instead of just balloon-like. Is assigned a pink palette instead of a blue one.
217	--	--				--	--	--	バリリーナ Baririina From barrier and ballerina.		Normal	Scrapped Mr. Mime pre-evolution which reuses the name originally assigned to it. Essentially an egg-shaped little dancing jester. Its egg-like design was perhaps inspired by the concept of "egg registery". Evolves into Mr. Mime starting at Level 15. Mr. Mime would later receive a pre-evolution, Mime Jr., in Generation IV, with it even having a similar pose to the one seen here.
218	238	Smoochum							リップ Rippu Lip	ムチュール Muchuuru	Ice	Has a design more akin to Jynx, complete with a long dress, a tidy hairstyle, and a black face.
219	239	Elekid							エレべビー Erebebii Elebaby	エレキッド Elekid	Electric	Has a more baby-like design, with a cuter face, no arms, no lightning chest pattern, and a different horn design.
220	240	Magby							Identical	ブビィ Bubii	Fire	Has a spikier head, a different facial expression, and a stomach pattern more akin to Magmar's.
221	182	Bellossom							Identical	キレイハナ Kireihana	Grass/Poison	Is larger overall, is surrounded by scent particles much like Gloom, and has more elaborate head flowers. Interestingly, its skin is also dark, much like the rest of the Oddish line, something which was changed quite late in development.
222	--	--				--	--	--	ツボミット Tsubomitto From 蕾 tsubomi (bud) and mitt.		Grass/Poison	Scrapped Weepinbell branched evolution, meant to be a parallel to Bellossom. The "mitt" from its name may hint at a baseball theme, with this Pokémon somewhat resembling a pitcher, which would make sense given how the Bellsprout line is based on pitcher plants.
223	241	Miltank							Identical	ミルタンク Miltank	Normal	A rounder, more imposing Miltank, complete with a very slightly different head design and perkier nipples. Is assigned a brown palette instead of a pink one.
224	--	--				--	--	--	ボムシカー Bomushikaa From bomb, アシカ ashika (sea lion), and seeker.		Water/Fire	A scrapped dual Water/Fire Pokémon resembling a circus seal balancing a magma ball on its nose. The Water/Fire typing would remain unutilized until the introduction of Volcanion in Generation VI, and the idea of a circus seal Pokémon then revisited in Generation VII with Popplio, though without the fire theme.
225	225	Delibird							ギフト Gifuto Gift	デリバード Delibird	Water/Ice	Has no eyebrows, a Santa "hat" on its head, and heart-shaped stomach spot.
226	--	--				--	--	--	コトラ Kotora From 子 ko child and トラ tora (tiger).		Electric	Scrapped tiger Pokémon which was originally created for Generation I. Essentially an adorable round feline which appears to be based on tiger-shaped clay bells, with the crack from which the bell can be heard becoming the thunder symbol on its belly. Evolves into Raitora starting at Level 35.
227	--	--				--	--	--	ライトラ Raitora From 雷 rai (thunder) and トラ tora (tiger).		Electric	Kotora's evolution, which was also originally created for Generation I, and retains the clay bell basis.
228	--	--				--	--	--	マダーム Madaamu	マダム Madame	Normal/Flying	Scrapped Farfetch'd evolution. Essentially an elegnt swan/goose holding a wild onion. Given its elegant name, appearance, and pose, it may have been based on masquerade dancers. Evolves from Farfetch'd starting at Level 24. Farfetch'd would only receive an evolution, Sirfetch'd, in Generation VIII, though this evolution has been confirmed as being unrelated to this design.
229	--	--				--	--	--	ノロワラ Norowara From 呪われる norowareru (to be cursed) and 藁人形 wara ningyō (straw doll).		Ghost	A scrapped Pokémon based on both a voodoo doll and a bear. Was designed after its signature move, Nail Down, a predecessor to Curse. Evolves into Kyonpan starting at Level 1.
230	--	--				--	--	--	キョンパン Kyonpan From キョンシー kyonshii and panda.		Ghost	A scrapped Pokémon based on both a jiangshi (a vampire-like mythological creature from Chinese mythology) and a panda. Given how Norowara resembles a teddy bear, then perhaps Kyonpan was based on a plushie, which would be supported by a cut item pairing related to sewing. If that's the case, then this line may have inspired the Shuppet line from Generation III, which is also based on haunted toys.
231	198	Murkrow							Identical	ヤミカラス Yamikarasu	Dark/Flying	Front sprite is very similar to the final, albeit with a longer tail, different eyes, a much witchier crest, and one less toe on each foot.
232	242	Blissey							ハッピー Happii Happy	ハピナス Happiness	Normal	Has a more Chansey-like design, though now with two egg pouches, fleshier hair, and a heart "hat".
233	212	Scizor							シザース Shizaasu Scissors	ハッサム Hassamu	Bug/Flying	Alongside the change to a Bug/Steel typing, this Pokémon would go on to be made more robotic, losing its mouth, detailing on its pincers, and becoming bright red instead green.
234	--	--				--	--	--	プラックス Purakkusu Plucks		Bug	Scrapped Pinsir evolution. Essentially a larger, fiercer-looking Pinsir with a face more akin to a mask. Evolves from Pinsir starting at Level 42. May have inspired Heracross, given the similar arm shape and the fact that there exists an early Heracross sprite whose face is similar to Pinsir's.
235	228	Houndour							デビル Debiru Devil	デルビル Derubiru	Fire	Front sprite had its pose tweaked and redrawn, while the back sprite was completely remade. The pattern on its back originally resembled a spinal column, matching with the rib cage and skull plate still featured in the final design.
236	229	Houndoom							Identical	へルガー Herugaa	Fire	Front sprite had its facial expression tweaked, while the back sprite was completely remade.
237	--	--				--	--	--	ウルフマン Urufuman Wolfman		Ice	A scraped Pokémon based on a mimic wearing a wolf pelt, making it look like a wolf itself, with its eyes poking out of its mouth and its hands emerging out of the fur. Evolves into Warwolf starting at Level 35. The concept of a Pokémon disguising itself would later be revisited in Generation VII with Mimikyu.
238	--	--				--	--	--	ワーウルフ Waaurufu Warwolf		Ice	Wolfman's evolution, with it now larger, its arms more defined and ending with claws. The concept of a Pokémon disguising itself would later be revisited in Generation VII with Mimikyu.
239	233	Porygon2							Identical	ポリゴン2 Porygon2	Normal	Has a more lion-like design, as opposed to a smoother interpretation of Porygon's design. Coincidentally shares a striking resemblance to Pon de Lion, the Mister Donut mascot, which didn't exist until 2003. Much like Manboo1, this Pokémon follows the placeholder naming scheme, though this name was ultimately kept, perhaps due to it evoking the idea of a V2 Porygon.
240	--	--				--	--	--	ナメール Nameeru From 舐める nameru (to lick).		Normal	Scrapped Lickitung evolution. Essentially a large Lickitung seemingly styled after snake charmers. With a turban of sorts, a curly mustache, and using its tongue like both a flute and a snake. Evolves from Lickitung starting at Level 32. Lickitung would later receive an evolution, Lickilicky, in Generation IV.
241	208	Steelix							Identical	ハガネール Haganeeru	Steel/Ground	Front sprite is nearly identical to the final with minor shading differences, whereas the back sprite exactly matches the final.
242	230	Kingdra				*			Identical	キングドラ Kingdra	Dragon/Water	Was made less dragon-like, and more akin to a leafy seadragon.
243	243	Raikou							ライ Rai From 雷 rai (thunder).	ライコウ Raikou	Electric	Has a radically different design, with it depicting Raikou not as a tiger, but as a moody canine with spiky thunder-like hair. The battle scar-like body markings likely went on to inspire the final design's stripes.
244	244	Entei							エン En From炎 en (fire).	エンテイ Entei	Fire	Has a radically different design, with it depicting Entei not as a lion, but as a cocky canine with fiery fur.
245	245	Suicune							スイ Sui From 水 sui (water).	スイクン Suicune	Water	Has a radically different design, with it depicting Suicune not as a leopard, but as a moppy canine with messy hair and a tail tied together with a gem, not unlike Zoroark's ponytail. Already has spots, and the wavy pattern on its legs likely went on to inspire the final design's flowing ribbons.
246	215	Sneasel							Identical	ニューラ Nyuura	Dark	Originally looked more like classical depictions of the Kamaitachi. The final games completely overhauled the design, but kept the brown palette. The sprites were then touched-up once again in the localized versions, before being "finalized" in Crystal.
247	250	Ho-Oh				*			Identical	ホウオウ Ho-Oh	Flying	Originally lacked a counterpart, making it more akin to Mewtwo when it comes to its singular legendary status. Front sprite was completely redrawn, whereas the back sprite only had its shading tweaked.
248	175	Togepi							Identical	トゲピー Togepi	Normal	Dex placement indicates a late addition. Is quite larger than its final counterpart. Has no evolution.
249	209	Snubbull							Identical	ブルー Buruu	Psychic	Dex placement indicates a late addition. Sprites were redrawn for the final; poses are the same. Uses a brown palette as opposed to a pink one. Has no evolution.
250	190	Aipom							テイル Teiru Tail	エイパム Aipom	Normal	Dex placement indicates a late addition. Originally looked more like a standard monkey. Has defined hands which are cream- instead of fur-colored, much like its ears. Its tail is also smaller, less stylized, and has four fingers instead of three. Uses a brown palette as opposed to a purple one.
251	--	--				--	--	--	リーフィ Riifi Leafy		Grass	Dex placement indicates a late addition. Scrapped Grass-type Eeveelution obtained after exposing an Eevee to a Leaf Stone. Was later reworked into Leafeon, a Generation IV Pokémon which even reused the name "Riifi" early in development.

Base Stats

Data Structure

The data structure is 31 bytes long, compared to Generation I's 28 bytes, and the final Generation II games' 32 bytes. The base stats data table is in Pokédex order (starting with Bulbasaur), and begins at address 0x50f10. The demo lacking the egg groups byte reveals that while breeding had already conceived, it had yet to be actually implemented.

Other than that, the data structure is essentially the same as the final Gold and Silver one, with the only remaining difference is that the final table lacks the address of the front and back Pokémon sprites for the Pokémon, unlike Generation I and this demo. Interestingly enough, however, the final table does have a zero-filled four-byte section where these addresses were.

Original 151

Of the 151 returning Pokémon, 95 of them received changes to their Special Attack or Special Defense between the demo and the final version. In general, Pokémon have higher Special Attack and lower Special Defense in the final version. The Bellsprout, Magnemite, and Tangela evolutionary lines received the most drastic changes.

The Pokémon's demo stat is listed first, and its final stat is listed second.

Demo 152-251

All of the new Pokémon have a placeholder catch rate of 255, along with a base experience of either 100 or 64, and many of them use 50s as a placeholder. They virtually all share a Medium Slow growth rate, with the only exceptions being Crobat, Slowking, and Elekid, which have a Medium Fast rate. The entirety of the new roster is assigned the same TM flag data, with them being able to learn TMs 1, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 22, 24, 25, 29, 30, 31, 32, 33, 34, 35, 36, 38, 40, 44, 45, 46, 49, 50, 54, and 55.

Interestingly, some stats appear to have been cloned from Gen 1 Pokémon during development, with the SpD dummied out.

• Slowking and Politoed's stats were cloned from Slowbro and Poliwrath respectively.
• Rai and En's stats were cloned from Zapdos and Moltres.
• Sui appears to use a previous revision of Articuno's stats, with the Special Attack still being 125 from before it was swapped.

Gender Ratios

Despite gender having been implemented, it is still in a visibly early state. Namely, only the 50/50, purely Male, purely Female, and Gender Unknown ratios have been implemented, and even there differences are abound. Unless specified, the Pokémon mentioned below use the default 50/50 ratio:

• The starter, Eevee, Kabuto, Omanyte, Aerodactyl, and Snorlax lines were ultimately given the 87.5 Male/12.5 Female ratio.
• The Growlithe, Abra, Machop, and Magby lines, as well as Electabuzz, were ultimately given the 75 Male/25 Female ratio.
• The Cleffa, Vulpix, Wigglytuff, and Igglybuff lines were ultimately given the 25 Male/75 Female ratio.
• The Tauros line, as well as Tyrogue and Hitmontop, were ultimately given the Male Only ratio.
• The Chansey, Smoochum, and Miltank lines were ultimately given the Female Only ratio.
• The Staryu, legendary birds, Mewtwo, Mew, Unown, Porygon2, legendary beasts, and Ho-Oh lines were ultimately given the Gender Unknown ratio.
• Elekid is Male Only and Snubbull is Female Only, while in the final games they were ultimately given the 75 Male/25 Female and 25 Male/75 Female ratios respectively.
• Interestingly enough, the scrapped Pokémon Rinrin is Female Only, but its evolution, Berurun, has a 50/50 ratio.

Evolutionary Requirements

The various ways in which Pokémon which did make it into the final games can evolve in this prototype. Evolutionary stones work as intended, except for the newly introduced Heart and Poison Stones. Happiness-related evolutions don't yet exist at this point of development, whereas all items necessary for a trade evolution are functional.

Interestingly, the demo uses a rather odd, possibly placeholder evolution method for Tyrogue, where it evolves into Hitmonlee upon reaching level 15, then immediately proceeds to evolve into Hitmonchan, and then Hitmontop right after. The evolution can be stopped at any point, thus letting you choose which Pokémon you want, albeit in a somewhat clumsy fashion. If left untouched, you will end up with a Hitmontop, though all three Hitmons will be recorded in the Pokédex. Meanwhile, Eevee evolving via a Leaf Stone was ultimately implemented into Generation VIII as the way to obtain Leafeon, due to the lack of a Moss Stone in those games.

It's also worth noting that here, Quagsire, Marill, Sunflora, Togepi, and Snubbull are all single-stage Pokémon. This is due to Wooper, Azumarill, Sunkern, Togetic, and Granbull being missing from this build of the games.

Cries

While all Generation I Pokémon make a return with their proper cries, the newly introduced Pokémon mainly use placeholder cries, though a few unique ones do exist.

Shinies

Shiny Pokémon already exist in this build, albeit in a rather rudimentary form. Unlike in the final games, the DV requirement for shininess is simply to have 10 or higher in each non-HP stat, yielding an appearance rate of 81/4096 or ~1.977% (considerably higher than the final's rate of 1/8192). Upon encountering one in the wild, no special animation will play out; the proper send-out animation used for shiny Pokémon in the final games is actually implemented, but for some reason it is only assigned to non-shiny Pikachu and Sunflora.

Due to this build being for the Super Game Boy as opposed to the Game Boy Color, the array of colors available is incredibly limited. As such, in addition to the 10 Pokémon palettes returning from Red and Green, another 10 were added as their shiny equivalents. Thus, all Pokémon of a given palette also share the same shiny coloration.

Oddly enough, the shiny palette applied to pink Pokémon has the lighter pink turned to a baby blue, while the darker pink becomes the same shade as the lighter one. This improper palette causes the sprites to which it is assigned to look messed up, and so it's likely that this second shade was instead supposed to be a darker shade of blue, as seen below:
