Team Dark in Robot Carnival.
8 to 12 waves of Dr. Eggman's robots.
The difficulty depends on the Team selected. If the player plays the stage with Team Dark, Eggman "reveals" to Shadow that he has no past to remember, assuming he is a Shadow Android. Team Sonic, Team Dark and Team Chaotix fight twelve waves of robots while Team Rose fight an easier eight waves.
This boss is notably easier for Team Chaotix, due to their Team Blast, Chaotix Recital, which adds Rings for every enemy destroyed on the field. The rings allow the move to be performed again. The same applies for Robot Storm.
- After defeating this boss, Eggman says "Don't get too excited, boys", even if the team has female characters.
- Also, in the subtitles, Eggman says "Don't get so excited, boys", instead of too.
