The ending credits vary depending on how many Chaos Emeralds you collected throughout the game:
- If you collected all 7 Emeralds, Sonic transforms into Super Sonic and flies and poses, while Dr Robotnik will be seen standing angrily.
- If you didn't collect them all, Sonic jumps off the "Sonic F" plane and poses, while Robotnik will be happily juggling the Emeralds you missed.
Sonic is seen running back and forth rapidly to form the Sega logo.
