SegaSonic the Hedgehog was Sonic the Hedgehog, Mighty the Armadillo, and Ray the Flying Squirrel's only game together until the release of Sonic Mania Plus in 2018.
Early versions of the characters on the title screen, without the shine on the eyes and the nose missing/unfinished. While Sonic was seen in the prototype, Ray and Mighty were nowhere to be seen outside of the graphics data.
Player Character Graphics
Some sprites of the characters flexing their muscles, which possibly would have been used when continuing the game. The code to have these animations display in-game still exists, but doesn't appear to be used anywhere.
Sonic had his face mercifully redrawn to look less like roadkill, while Ray got his patagia enlarged.
Sonic got his arms reanimated, Ray had his proportions slightly corrected, and Mighty's face was redrawn.
Dr. Eggman Sprites
It seems that Eggman was supposed to use some gadgets and thingamajigs himself to prevent players from reaching him. Probably meant to show up in other stages in Eggman Island more than waiting for the main character(s) to meet him at the computer room in the final level.
Unused Localization Version
Although the international releases were, for whatever reason, not localized or translated, there are many remnants of plans to do so.
A largely complete set of sprites of Robotnik as he looked on ABC's Sonic the Hedgehog cartoon (generally nicknamed SatAM) and in Archie's Sonic comics. The only sprites that appear to be missing are for him riding around behind the title screen and the intro where he traps the main character(s) while riding on an Eggman-face tank.
Even the little details were accounted for to complete the Robotnik experience.
A complete set of English dialogue bubbles. Interestingly, one of the bubbles has an "Eggman" variant.
These might have been used when setting to multiple coins per one credit, but they don't appear no matter what dipswitch settings are used.
A sprite viewer menu of sorts.
