The original for Sonic the Hedgehog (1991) was limited by the SEGA Genesis’s color palette (61 colors on screen). Sonic was designed to be a simple, fat, round hedgehog. By Sonic 3 & Knuckles (1994), the sheets had evolved dramatically. Sprites became taller, slimmer, and more detailed, introducing "Super Sonic" with bright yellow-gold hues and flowing quills.
Sonic CD introduced the "Peel Out" (a wind-up dash). Consequently, the for CD includes unique wind-up frames not found in the Genesis trilogy. The sprites are slightly more rounded, matching the anime-inspired cutscenes.

His sheet is massive because his tails have to follow physics independent of his body. In the running sheet, you see a beautiful "caterpillar" wave—tails 1, 2, and 3 moving in sequential arcs.

: Because the sheet was incomplete, many of Super Sonic's animations in that game are simply the base Sonic sprites recolored gold rather than unique drawings.
One of the most fascinating aspects of retro Sonic sprite sheets is color management. The Sega Genesis had a limited color palette (64 colors on-screen total). Sprite sheets often use a specific "key color" (usually a shade of bright pink or neon green) for the background. This color tells the game engine, "Do not render this pixel," creating transparency. The sprites are slightly more rounded, matching the
