Standard Party Members

Shulk

File name	Speech	Description
ahx.pkb_032	"Reyn!"	These lines were likely intended to have been said by Shulk when the respective character dies. Because of how chaotic battles can get sound-wise, it was probably why these lines were dropped.
ahx.pkb_033	"Fiora! Please, no!"
ahx.pkb_034	"No way! Dunban!"
ahx.pkb_035	"Sharla!"
ahx.pkb_036	"Riki!"
ahx.pkb_037	"Melia!"
ahx.pkb_127	"I just can't get it together."	These two lines are stored just after Shulk's "tension increased" lines, so they were most likely intended to be his low tension and very low tension counterparts, respectively. The fact that the files lack any response lines for these may indicate they were cut pretty early on.
ahx.pkb_128	"Hey... My heart's not in this."
ahx.pkb_131	"EVERYONE! YOU'RE THE BEST!"	Stored after Shulk's "party gauge is two bars full" line, so it's very likely the original "party gauge is full" line. It's unknown why his lines were changed to mention chain attacks instead. This might indicate that originally chain attacks were either not tied to the party gauge or had an additional requirement before they could be used (possibly a fourth bar for the party gauge?).
ahx.pkb_144	"It's 'cause we all make such a great team, Reyn!"	This group is stored after Shulk's "NPC response to party gauge being two bars full" lines, so they're very likely the original "NPC response to party gauge being full" lines. See above line for more notes.
ahx.pkb_145	"I feel exactly the same, Fiora!"
ahx.pkb_146	"Yes sir!"
ahx.pkb_147	"Yeah! It's cool, isn't it Sharla?!"
ahx.pkb_148	"Right behind you, Riki!"
ahx.pkb_149	"Melia, thank you!"
ahx.pkb_164	"Stay with me!"	Stored between Shulk's lines for having his status effect be healed and him being revived by someone, so it could have been meant for him doing either for someone else. Because lines are typically stored in alternating "reaction-response" order and this line is stored between two "response sets", it's more likely to be meant for revival. Why it went unused is unknown.
ahx.pkb_196	"This might not be so good."	These three are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all. The third line is particularly odd in that Sharla's and Melia's lines stored in that spot are used (for responding after the other party members congratulate them for their crit/dodge) but everyone else's aren't.
ahx.pkb_197	"Let's finish this!"
ahx.pkb_199	"I've got a good feeling about this!"
ahx.pkb_210	"Reyn! It's up to you!"	Stored after lines related to giving and receiving aid from other party members (via them healing/buffing Shulk or taking enemy aggro off of him). See below for a potential explanation for this set.
ahx.pkb_211	"Fiora! You got it?"
ahx.pkb_212	"Dunban! That's the one!"
ahx.pkb_213	"Sharla! You're needed here!"
ahx.pkb_214	"Riki! Take the lead!"
ahx.pkb_215	"Melia! That's the one!"
ahx.pkb_216	"Okay, understood!"	Stored between the previous unused set and Shulk's "issuing battle commands" lines. No way to know for sure what exactly these were meant to be for, but since they're stored near the lines that play when the player directs the behavior of the NPC party members, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_217	"I don't think I can manage it!"
ahx.pkb_218	"I'll give it a shot!"
ahx.pkb_221	"Strike hard and fast!"	This pair is stored after Shulk's "issuing battle commands" lines, so these were most likely meant for unimplemented battle commands.
ahx.pkb_222	"Tread carefully!"
ahx.pkb_252	"The light of the Monado is fading!"	Stored in the same spot the other characters have their lines reacting to the Monado failing, which are stored after their respective "responding to Shulk using a Monado Art" lines. This implies that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well, and if so his line here would have played after the player tried to use a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_299	"I must be strong!"	Based on the storage order for every character's Arts lines, this is stored in the spot where Shulk's second Monado Enchant line should be. (In game he only has one line for Enchant, unlike the vast majority of his other Arts as well as every single other main party members' Arts.) However, what he says here doesn't really make sense for that criteria. Likely either meant for a scrapped Art, just used for testing, or was meant to be a placeholder for a second Enchant line that never ended up being made.
ahx.pkb_310	"Use my strength!"	This line is stored where his second Air Slash line should be (see above notes; he also only has one line for Air Slash). Again, his dialogue here doesn't make sense for Air Slash, though, so it's again either meant for testing, an unimplemented Art, or is a placeholder left over.
ahx.pkb_311	"I'll risk it!"	This line is stored where his second Shadow Eye line should be (see above notes; he also only has one line for Shadow Eye). Once again, what he says in the line doesn't make sense for Shadow Eye and therefore is more likely to be a placeholder/test/line for an unused Art. The dialogue does seem to fit Battle Soul, but it would be uniquely out of order storage-wise and he already has two lines for that Art, so it's very unlikely.
ahx.pkb_348	"Agh. This is tricky!"	These three lines are stored between Shulk's gem crafting lines and his lines for jumping. It's possible they were meant for something entirely unique, but considering the fact that every character's lines for starting gem crafting are stored at the end of the "gem crafting set" it's also likely these were going to be last-minute gem crafting additions (potentially affinity-related?) that never got added due to time/budget restraints. Interestingly, though, you can actually fail at gem crafting if you try hard enough (there's even a special animation and graphic for doing so), but this line doesn't play even though it would make sense for the situation. Very odd.
ahx.pkb_349	"Cool!"
ahx.pkb_350	"I like it!"
ahx.pkb_354	"Even if the Monado doesn't effect him, we can still see visions and find another way! Yaah!"	Likely meant to have played during the battle with Metal Face in Colony 9.
ahx.pkb_356	"The Monado doesn't effect this one either, we've gotta hold on somehow!"	Likely intended for the first battle with Xord/Mysterious Face.
ahx.pkb_360	"Not gonna work!"	The fact that this line is Shulk's very last non-cutscene voice line and that every single playable character (even the temporary ones of Mumkhar, Dickson, and Alvis) has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

Reyn

File name	Speech	Description
ahx.pkb_384	"Shulk!"	Likely intended for when another character died. It should be noted that "Old Man" refers to Riki which, despite being potentially confusing or even a spoiler for the player, Reyn does call him similar nicknames in other lines, both used and unused.
ahx.pkb_389	"Fiora!"
ahx.pkb_387	"Dunban!"
ahx.pkb_386	"Sharla!"
ahx.pkb_388	"Old Man!"
ahx.pkb_385	"Melia!"
ahx.pkb_477	"Gah... I can't get warmed up!"	These two were most likely intended to play when Reyn reaches low tension and very low tension, respectively.
ahx.pkb_478	"Nah... I can't get into it!"
ahx.pkb_481	"WE ARE THE GREATEST!"	These are very likely Reyn's original "party gauge is full" lines.
ahx.pkb_494	"That's right! Ain't no stoppin' us!"
ahx.pkb_495	"WOO hoo! Stop it, Fiora! Yer makin' me CRY!"
ahx.pkb_496	"You can count on me, Dunban!"
ahx.pkb_497	"I dunno what you MEAN, Sharla, but III LOVE IT!"
ahx.pkb_498	"Let's show 'em just how heroic we can be!"
ahx.pkb_499	"Yeah, Melia! Let's smash 'em to bits!"
ahx.pkb_514	"We're not losin' you!"	Most likely to be meant for Reyn reviving another party member.
ahx.pkb_545	"This ain't lookin' peachy."	These three are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all.
ahx.pkb_546	"Keep up the pressure, guys!"
ahx.pkb_548	"Hey! We're doin' pretty well!"
ahx.pkb_556	"Fiora, you always were the thoughtful type."	This line is stored among lines related to giving and receiving aid from other party members (via them healing/buffing Reyn or taking enemy aggro off of him). Oddly, Shulk's line thanking Fiora for taking aggro off of him is used, even though this line of Reyn's isn't. Though one of Fiora's unused lines (see her section below) may imply that she was originally meant to have a party-healing or -buffing Art, and if so it's possible Reyn's line here was programmed to be played in response to that rather than her taking aggro.
ahx.pkb_558	"Shulk, it's that one!"	No way to know for sure what exactly these were meant to be for, but since they're stored near Reyn's lines that play when the player directs the behavior of the NPC party members via battle commands, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_559	"Fiora, I'm countin' on ya!"
ahx.pkb_560	"Dunban! It's all yours!"
ahx.pkb_561	"Sharla! Show 'em the business end o' your rifle!"
ahx.pkb_562	"Hit 'em with yer walkin' stick, Riki!"
ahx.pkb_563	"Melia! Get that one!"
ahx.pkb_564	"I'm right on it!"
ahx.pkb_565	"Gah! Can't get 'em from here!"
ahx.pkb_566	"Guess I'll just go for it!"
ahx.pkb_569	"Everyone get in the fray!"	This pair was most likely meant for unimplemented battle commands.
ahx.pkb_570	"Keep yer guard up!"
ahx.pkb_599	"Wha? Is this for real?"	Stored after Reyn's "responding to Shulk using a Monado Art" line, implying that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well. If so, Reyn's line here would've played while the player is controlling him after NPC-party-member Shulk tried using a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_626	"I won't let 'em lay a single finger on you, Sharla!"	Stored among Reyn's post-battle voice lines. The fact that Sharla is mentioned by him as well as her being the only other party member who has an unused line in this section heavily implies this conversation was meant to happen while the two were the only members of the party. However, the only time this is the case (which is on the Fallen Arm) it is impossible to encounter enemies, therefore these lines cannot be triggered.
ahx.pkb_696	"Aw man, this is a pain!"	These three lines could possibly have been meant for something entirely unique but, due being stored after Reyn's gem crafting lines, it's likely these were going to be played under last-minute gem crafting criteria that never got implemented because of time/budget restraints.
ahx.pkb_697	"Yeah, I like it!"
ahx.pkb_698	"Heheh, lookin' good!"
ahx.pkb_704	"Rock-solid!"	The fact that this line is Reyn's very last non-cutscene voice line and that every single playable character has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

Fiora

File name	Speech	Description
ahx.pkb_728	"No, Shulk! You can't die!"	Likely intended for when a character died.
ahx.pkb_729	"Reyn! No!"
ahx.pkb_730	"No! Dunban! No!"
ahx.pkb_731	"Sharla! Don't die!"
ahx.pkb_732	"Riki! Talk to me, please!"
ahx.pkb_733	"No way! Melia!"
ahx.pkb_746	"Dickson!"	This line is stored at the end of Fiora's "another party just dodged/landed a crit" lines, likely indicating what it was meant for. Its existence is odd not only because the two are never in a party together, not only because Fiora strangely lacks a matching "Dickson's attack missed/got blocked" line, but also because Dickson doesn't even have a single voice line where he refers to Fiora. It's possible this indicates just how early in development whatever battle that had the two in the party together was cut.
ahx.pkb_820	"Ahh... I don't feel so good."	These two were most likely intended to play when Fiora reaches low tension and very low tension, respectively.
ahx.pkb_821	"My arms and legs feel so heavy."
ahx.pkb_824	"Fighting alongside you all is the BEST!"	These are very likely Fiora's original "party gauge is full" lines.
ahx.pkb_837	"I'm... happy! Thank you, Shulk!"
ahx.pkb_838	"I feel the same way, Reyn!"
ahx.pkb_839	"Yes sir! ...Like that, right?"
ahx.pkb_840	"Let's not lose this vibe, Sharla!"
ahx.pkb_841	"Heeheehee! Right behind you, mighty Riki!"
ahx.pkb_842	"Aw, thank you, Melia!"
ahx.pkb_857	"Please... Open your eyes."	Most likely to be meant for Fiora reviving another party member.
ahx.pkb_887	"Ohhh... This is bad."	These three are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all.
ahx.pkb_888	"Okay. We can do it!"
ahx.pkb_889	"Hey! Not bad!"
ahx.pkb_896	"Here. Dunban. For you!"	This line is stored among lines related to giving and receiving aid from other party members (via them healing/buffing Fiora or taking enemy aggro off of her). The wording of the line wouldn't make sense for her to say while taking aggro away from Dunban, so the only other criteria left is her healing or buffing him. However, she lacks any Arts that can heal or buff other party members (both as Homs!Fiora and as Mecha-Fiora) in the final release.
ahx.pkb_900	"Shulk, please!"	No way to know for sure what exactly these were meant to be for, but since they're stored near Fiora's lines that play when the player directs the behavior of the NPC party members via battle commands, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_901	"Reyn, pay attention!"
ahx.pkb_902	"Dunban, I need you!"
ahx.pkb_903	"Sharla! We need action, fast."
ahx.pkb_904	"Riki! Can you do it?"
ahx.pkb_905	"Melia. Over there!"
ahx.pkb_906	"I'll deal with 'em."
ahx.pkb_907	"I can't really help, I'm afraid."
ahx.pkb_908	"Well... Here goes."
ahx.pkb_911	"Let's go all out!"	This pair was most likely meant for unimplemented battle commands.
ahx.pkb_912	"We need to keep our guard up!"
ahx.pkb_940	"But how?"	Stored after Fiora's "responding to Shulk using a Monado Art" line, implying that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well. If so, Fiora's line here would've played while the player is controlling her after NPC-party-member Shulk tried using a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_1037	"Don't blame me if it goes wrong."	These three lines could possibly have been meant for something entirely unique but, due being stored after Fiora's gem crafting lines, it's likely these were going to be played under last-minute gem crafting criteria that never got implemented because of time/budget restraints.
ahx.pkb_1038	"This is really nice!"
ahx.pkb_1039	"Yeah, I like it!"
ahx.pkb_1042	"Stopped you!"	The fact that this line is Fiora's very last non-cutscene voice line and that every single playable character has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

Dunban

File name	Speech	Description
ahx.pkb_1066	"Shulk! No!"	Likely intended for when another character in the party dies.
ahx.pkb_1067	"Reyn! I told you not to lose focus."
ahx.pkb_1068	"It... can't be. Fiora!"
ahx.pkb_1069	"No! Sharla!"
ahx.pkb_1070	"Riki!"
ahx.pkb_1071	"Melia! I'm sorry!"
ahx.pkb_1072	"Dickson!"	This pair of lines are stored just before part of Dunban's chain attack callout lines, meaning this is likely what these lines were meant for. This is supported by the fact that Dunban's audio files contain unused lines (see "Cutscene Audio") that imply the tutorial was meant to be more substantial, potentially to the point that chain attacks would have been introduced to the player. However, if this is true it was likely changed very early on in development, as even though it's possible to have Dickson participate in a chain attack with Dunban in game during the Freight Road battle, the first voice line seems to lack programming to ever be played.
ahx.pkb_1073	"Mumkhar!"
ahx.pkb_1161	"I'm having a lapse of concentration!"	These two were most likely intended to play when Dunban reaches low tension and very low tension, respectively.
ahx.pkb_1162	"I just cannot focus!"
ahx.pkb_1165	"Channel our unity... into strength!"	These are very likely Dunban's original "party gauge is full" lines.
ahx.pkb_1178	"Ahh, THIS is how we USED to fight!"
ahx.pkb_1179	"And let's keep it that way, Reyn!"
ahx.pkb_1180	"We're not done here yet, Fiora!"
ahx.pkb_1181	"Focus that energy, and let us finish this! Sharla!"
ahx.pkb_1182	"We shall follow your lead, Riki!"
ahx.pkb_1183	"Melia! Your kind words spur me on!"
ahx.pkb_1198	"Do you want to let it end like this?"	Most likely to be meant for Dunban reviving another party member.
ahx.pkb_1229	"This isn't good!"	These three are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all.
ahx.pkb_1230	"Cut the enemy down!"
ahx.pkb_1232	"Hmm! Not bad!"
ahx.pkb_1237	"Shulk... Go!"	No way to know for sure what exactly these were meant to be for, but since they're stored near Dunban's lines that play when the player directs the behavior of the NPC party members via battle commands, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_1238	"Reyn! There!"
ahx.pkb_1239	"Fiora! It's down to you!"
ahx.pkb_1240	"Sharla, I'm counting on you!"
ahx.pkb_1241	"Riki! Attack!"
ahx.pkb_1242	"Melia! Over there!"
ahx.pkb_1243	"Right! Here I go!"
ahx.pkb_1244	"I cannot reach from here!"
ahx.pkb_1245	"Are we ready?!"
ahx.pkb_1248	"Full-on assault!"	This pair was most likely meant for unimplemented battle commands.
ahx.pkb_1249	"Focus on defence!"
ahx.pkb_1278	"What?! How is this possible?!"	Stored after Dunban's "responding to Shulk using a Monado Art" line, implying that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well. If so, Dunban's line here would've played while the player is controlling him after NPC-party-member Shulk tried using a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_1327	"One!"	Located amongst the lines for Dunban's arts. Judging from the way these are structured, as well as the fact that they're located just before his finalized Talent Art lines, these were placeholders for Dunban's Blossom Dance.
ahx.pkb_1328	"Two!"
ahx.pkb_1329	"Three!"
ahx.pkb_1330	"You're finished!"
ahx.pkb_1368	"This really isn't my speciality!"	These three lines could possibly have been meant for something entirely unique but, due being stored after Dunban's gem crafting lines, it's likely these were going to be played under last-minute gem crafting criteria that never got implemented because of time/budget restraints.
ahx.pkb_1369	"Hmm, I'm warming to it!"
ahx.pkb_1370	"I like it!"
ahx.pkb_1373	"Mumkhar, you're lagging behind!"	Likely intended for some time in the first battle. It should be noted, however, that Mumkhar does not spawn within the barrier that Dunban and Dickson are spawned inside of during the beginning of the battle and takes a few seconds before arriving inside.
ahx.pkb_1374	"Start with those in front of you!"	Again, likely intended for the first battle.
ahx.pkb_1375	"Not likely!"	The fact that this line is Dunban's very last non-cutscene voice line and that every single playable character has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

(Source: Iggy [death lines, Mumkhar callout's audio file, Blossom Dance placeholders' audio files and most of its notes, "Mumkhar, you're lagging behind!", "Start with those in front of you!", Monado failing line's audio file, final line's audio file], Kadoodles [everything else])

Sharla

File name	Speech	Description
ahx.pkb_1399	"Shulk! Get up, please!"	Likely intended for when the respective character dies.
ahx.pkb_1400	"No, Reyn! Reyn!"
ahx.pkb_1401	"Fiora! Don't die!"
ahx.pkb_1402	"That's not possible! Dunban!"
ahx.pkb_1403	"Riki? Riki! Riki!"
ahx.pkb_1404	"Melia, I'm so sorry!"
ahx.pkb_1492	"I just can't keep focused!"	These two were most likely intended to play when Sharla reaches low tension and very low tension, respectively.
ahx.pkb_1493	"I don't see how we can win!"
ahx.pkb_1496	"All of our hearts and minds as one!"	These are very likely Sharla's original "party gauge is full" lines.
ahx.pkb_1509	"You too, Shulk!"
ahx.pkb_1510	"We already KNOW that, Reyn!"
ahx.pkb_1511	"Heehee, calm down, Fiora! We're not going anywhere!"
ahx.pkb_1512	"Okay, Dunban!"
ahx.pkb_1513	"But YOU'RE the one falling behind!"
ahx.pkb_1514	"We're counting on you, Melia!"
ahx.pkb_1592	"I don't want to lose anyone else!"	Most likely to be meant for Sharla reviving another party member.
ahx.pkb_1560	"I'm not liking this."	These two are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all. Of note, one line stored in this area is used for Sharla and Melia, while its equivalent goes unused for everyone else.
ahx.pkb_1561	"Let's keep this up, guys!"
ahx.pkb_1569	"That one, Shulk!"	No way to know for sure what exactly these were meant to be for, but since they're stored near Sharla's lines that play when the player directs the behavior of the NPC party members via battle commands, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_1570	"Reyn, do your thing!"
ahx.pkb_1571	"Fiora! I need you!"
ahx.pkb_1572	"Dunban, strike hard 'n' fast!"
ahx.pkb_1573	"Riki! Get 'em!"
ahx.pkb_1574	"Melia! Over there!"
ahx.pkb_1575	"Here goes!"
ahx.pkb_1576	"I can't get a clear shot!"
ahx.pkb_1577	"Ready?"
ahx.pkb_1580	"Let's go all out!"	This pair was most likely meant for unimplemented battle commands.
ahx.pkb_1581	"Concentrate on defence!"
ahx.pkb_1610	"What? No way, the Monado!"	Stored after Sharla's "responding to Shulk using a Monado Art" line, implying that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well. If so, Sharla's line here would've played while the player is controlling her after NPC-party-member Shulk tried using a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_1631	"Thank you... Reyn."	Stored among Sharla's post-battle voice lines. The fact that Reyn is mentioned by her as well as his being the only other party member who has an unused line in this section heavily implies this conversation was meant to happen while the two were the only members of the party. However, the only time this is the case (which is on the Fallen Arm) it is impossible to encounter enemies, therefore these lines cannot be triggered.
ahx.pkb_1694	"I hope we can do it."	These three lines could possibly have been meant for something entirely unique but, due being stored after Sharla's gem crafting lines, it's likely these were going to be played under last-minute gem crafting criteria that never got implemented because of time/budget restraints.
ahx.pkb_1695	"Hmm! Looking good!"
ahx.pkb_1696	"Yeah! Really suits me!"
ahx.pkb_1699	"Not a chance!"	The fact that this line is Sharla's very last non-cutscene voice line and that every single playable character has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

Riki

File name	Speech	Description
ahx.pkb_1723	"Ooh. Shulk, what wrong?"	Guess what.
ahx.pkb_1724	"Reyn no fall down."
ahx.pkb_1725	"Fiora is sleepy?"
ahx.pkb_1726	"Dundun is hungry?"
ahx.pkb_1727	"Sharla, why you no move?"
ahx.pkb_1728	"Melly, please move!"
ahx.pkb_1814	"Phew! Riki tired now."	These two were most likely intended to play when Riki reaches low tension and very low tension, respectively.
ahx.pkb_1815	"Riki want to go home."
ahx.pkb_1818	"All follow Riki!"	These are very likely Riki's original "party gauge is full" lines.
ahx.pkb_1831	"Riki and friends the best!"
ahx.pkb_1832	"But Riki more greatest than Reyn!"
ahx.pkb_1833	"Riki so happy FIORA so happy!"
ahx.pkb_1834	"Heropon here to save dayyy!"
ahx.pkb_1835	"And tummies and paws as one!"
ahx.pkb_1836	"Melly fight hard, Riki COPY Melly!"
ahx.pkb_1851	"Time for din-dins! ...Yeaaah!"	Most likely to be meant for Riki reviving another party member.
ahx.pkb_1881	"Hmm. Riki not happy."	These three are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all.
ahx.pkb_1882	"Yeah! Go go go!"
ahx.pkb_1884	"GO, Riki and friends!"
ahx.pkb_1888	"Reyn got the stupids!"	This pair is stored in a location where other party members have their lines related to giving and receiving aid from other party members (via them healing/buffing them or taking enemy aggro off of them). This storage spot, plus the fact that Riki is responding to something Reyn said in both lines, combined with him calling Reyn "greedy" in the second one near-certainly implies when these were meant to be heard. The first would play at some point after Reyn's "received a heal/buff from Sharla" line, and the second would play at some point after his "witnessed someone else get a heal/buff from Sharla" line (where she calls him "greedy"), respectively. It's unknown, however, whether these were meant to be responses to Sharla's replies to Reyn, or alternative responses directly to Reyn that had a chance to play instead of Sharla's.
ahx.pkb_1889	"Reyn, no be greedy!"
ahx.pkb_1890	"Shulk! Go-go!"	No way to know for sure what exactly these were meant to be for, but since they're stored near Riki's lines that play when the player directs the behavior of the NPC party members via battle commands, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_1891	"Reyn! Listen to Riki!"
ahx.pkb_1892	"Bash that one, Fiora!"
ahx.pkb_1893	"Riki leave that one for Dundun!"
ahx.pkb_1894	"Sharla, shoot that one!"
ahx.pkb_1895	"Melly! Ka-pow zing!"
ahx.pkb_1896	"Heropon to rescue!"
ahx.pkb_1897	"Riki no can do!"
ahx.pkb_1898	"Riki go now."
ahx.pkb_1901	"Super-duper attack!"	This pair was most likely meant for unimplemented battle commands.
ahx.pkb_1902	"Hmph! Defend, defend!"
ahx.pkb_1930	"Monado! What wrong?"	Stored after Riki's "responding to Shulk using a Monado Art" line, implying that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well. If so, Riki's line here would've played while the player is controlling him after NPC-party-member Shulk tried using a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_2020	"Riki bored."	These three lines could possibly have been meant for something entirely unique but, due being stored after Riki's gem crafting lines, it's likely these were going to be played under last-minute gem crafting criteria that never got implemented because of time/budget restraints.
ahx.pkb_2021	"This cool!"
ahx.pkb_1696	"This Riki favourite!"
ahx.pkb_2035	"Riki stop you!"	The fact that this line is Riki's very last non-cutscene voice line and that every single playable character has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

Melia

File name	Speech	Description
ahx.pkb_2059	"Shulk! It can't be!"	Likely intended for when the respective character dies.
ahx.pkb_2060	"By the Bionis, Reyn!"
ahx.pkb_2061	"Fiora! No!"
ahx.pkb_2062	"That one such as Dunban could fall so easily..."
ahx.pkb_2063	"Sharla, stay with us!"
ahx.pkb_2064	"Riki! Get up, please!"
ahx.pkb_2150	"My concentration wanes."	These two were most likely intended to play when Melia reaches low tension and very low tension, respectively.
ahx.pkb_2151	"My composure has left me."
ahx.pkb_2154	"I shall honour everyone's trust in me!"	These are very likely Melia's original "party gauge is full" lines.
ahx.pkb_2167	"I have been blessed with good friends! Thank you, Shulk."
ahx.pkb_2168	"Reyn! ...Consign the enemy to oblivion!"
ahx.pkb_2169	"That sent shivers down my spine, Fiora!"
ahx.pkb_2170	"Understood, Dunban!"
ahx.pkb_2171	"This sensation... It is truly amazing, Sharla!"
ahx.pkb_2172	"I am with you, Riki!"
ahx.pkb_2187	"You still have much to do."	Most likely to be meant for Melia reviving another party member.
ahx.pkb_2217	"I don't like this feeling."	These two are stored among lines that have very specific and niche criteria to be heard. Not sure what they could have been meant for, or if they're even unused at all. Of note, one line stored in this area is used for Melia and Sharla, while its equivalent goes unused for everyone else.
ahx.pkb_2218	"Drive the enemy back!"
ahx.pkb_2224	"Shulk! I'll leave that one to you!"	No way to know for sure what exactly these were meant to be for, but since they're stored near Melia's lines that play when the player directs the behavior of the NPC party members via battle commands, it's possible some kind of auto-battle system was going to be implemented and these lines were meant to play when initiating it.
ahx.pkb_2225	"Forward, Reyn!"
ahx.pkb_2226	"Fiora! Can you help?!"
ahx.pkb_2227	"It is up to you, Dunban!"
ahx.pkb_2228	"Sharla! Is your line of fire clear?"
ahx.pkb_2229	"Let us witness the might of the Heropon!"
ahx.pkb_2230	"Proceeding!"
ahx.pkb_2231	"I cannot target it."
ahx.pkb_2232	"If there is no other option."
ahx.pkb_2235	"Strike with all your might!"	This pair was most likely meant for unimplemented battle commands.
ahx.pkb_2236	"Defence is the best policy!"
ahx.pkb_2264	"The Monado has abandoned us."	Stored after Melia's "responding to Shulk using a Monado Art" line, implying that it's possible the Apocrypha was originally going to affect Shulk's ability to use the Monado during gameplay as well. If so, Melia's line here would've played while the player is controlling her after NPC-party-member Shulk tried using a Monado Art in battle but got unlucky and couldn't.
ahx.pkb_2314	"Go!"	This line is stored in the spot where her Talent Art line should be, and sure enough one of her used Talent Art lines follows this one. This means it's very likely this line was a placeholder used to test Elemental Discharge.
ahx.pkb_2332	"Elemental Burst!"	Melia calling the name of her Talent Art. Because of the way her Elemental Burst talent art works, it would make no sense for this line to be used, and therefore it's likely this was just used to test her Talent Art and/or her Elemental Burst state's activation.
ahx.pkb_2333	"Elemental Shoot!"	Another testing placeholder used to test Melia firing her elementals.
ahx.pkb_2334	"Dark Element!"	This line could imply that Melia was meant to have an additional elemental type, but because this line is stored among the bulk of her Talent Art lines rather than her summoning Arts lines, it's more likely this was yet another placeholder.
ahx.pkb_1694	"Can't say I'm enthusiastic about this."	These three lines could possibly have been meant for something entirely unique but, due being stored after Melia's gem crafting lines, it's likely these were going to be played under last-minute gem crafting criteria that never got implemented because of time/budget restraints.
ahx.pkb_1695	"I think this is rather fetching!"
ahx.pkb_1696	"This pleases me."
ahx.pkb_2361	"Halt!"	The fact that this line is Melia's very last non-cutscene voice line and that every single playable character has a matching line here means its criteria is a complete and total mystery and, likely, a last-minute addition that the devs didn't end up having time to implement.

Temporary Party Members

Dickson

File name	Speech	Description
ahx.pkb_2368	"Mumkhar!"	Dickson calling out Mumkhar's name. Similar to the name callouts used for both chain attacks and burst affinity. During the time both Mumkhar and Dickson are in the same party, there are no burst affinity opportunities and the party gauge is disabled.
ahx.pkb_2381	"Riki!"	Dickson calling out Riki and Melia's name. Dickson never rejoins the party at any point after Melia and Riki join. Interestingly, these two lines don't exist in the Japanese version!
ahx.pkb_2382	"Melia!"
ahx.pkb_2390	"My bad luck, ends here and all..."	Likely intended have said this upon death. Dickson cannot die in the final game due to his unbeatable gem.

Mumkhar

File name	Speech	Description
ahx.pkb_2457	"Dunban!"	Mumkhar calling out Dunban and Dickson's names. During the Battle of Sword Valley there are no burst affinity opportunities and the party gauge is disabled.
ahx.pkb_2458	"Dickson!"
ahx.pkb_2459	"Yeah! Bring it on!"	Intended to have been used when starting a battle.
ahx.pkb_2460	"Ugh. Why me?"	Intended to have been used when starting a battle.
ahx.pkb_2461	"Hey! Hey! You outta your mind!?"	Likely intended to have been used when encountering high-levelled enemies. No such enemies appear in the time you have Mumkhar in the party.
ahx.pkb_2465	"This ain't funny..."	Possibly intended to have been used when Mumkhar dies. Similar to Dickson, his unbeatable gem prevents him from dying in the final.
ahx.pkb_2468	"Stay still!"	Intended for use when Mumkhar misses and triggers a burst affinity.
ahx.pkb_2469	"You're havin' a laugh!"
ahx.pkb_2470	"What are you playing at?"	Lines likely intended when Mumkhar revives or helps a party member with a status condition. No characters can die during the time Mumkhar is in the party and no-one can be cured of status conditions either.
ahx.pkb_2471	"C'mon, get with it!"
ahx.pkb_2472	"You're slowing us down, mate!"
ahx.pkb_2479	"Way too slow!"	Likely meant to be used when Mumkhar's dodge triggers a burst affinity.
ahx.pkb_2474	"[laughs]"	Mumkhar laughing. Intended use unknown.
ahx.pkb_2477	"Ha ha! I could have done that!"	Likely meant to be lines for Mumkhar commenting on another team member's successful dodge through burst affinity.
ahx.pkb_2480	"Ha! Guess that won't stop you!"
ahx.pkb_2481	"Nice moves!"
ahx.pkb_2482	"I could've dodged that!"
ahx.pkb_2501	"Hell Dive Claw! Yeah, suffer!"	An alternate line intended for Mumkhar's Hell Dive Claw art.
ahx.pkb_2503	"I'll draw 'em to me. Dunban, you do that... blue business you do!"	Likely meant to have been spoken when starting the battle and filling the talent gauge respectively.
ahx.pkb_2504	"Hey! Enchant us already!"
ahx.pkb_2502	"I'll tear you limb from limb! [laughs]"	Unknown. The tone indicates this was likely meant to be used when starting a battle.

Alvis

File name	Speech	Description
ahx.pkb_2526	"This is... unexpected..."	The tone of the voice clip indicates Alvis would say this when he died. He can't die in the Telethia battle, the only time this would be used.
ahx.pkb_2589	"We should keep our guard up."	These lines were likely intended after finishing a battle with Alvis in the party. However, during the only battle he is available, it's impossible to start it without triggering all the opposing Telethia.
ahx.pkb_2590	"Do you want to rest?"
ahx.pkb_2591	"Let's tend to our injuries."
ahx.pkb_2592	"This area seems safe enough."
ahx.pkb_2593	"Right. Let us move on."
