Shadow the Hedgehog will return, but not in Sonic Superstars.
Sonic Team’s Takashi Iizuka was asked about Shadow’s appearance in Sega’s upcoming multiplayer platformer during a Shacknews interview this week. The “classic” characters are the focus of this 3D entry.
“Unfortunately Shadow’s not in the game – sorry all you Shadow fans, this is a classic series game, so do understand Shadow is not a part of the classic series.”
Iizuka said Sonic Team wants to make a Shadow game for fans in the future, even though it doesn’t sound good. Shadow also appears in Sonic Prime on Netflix.
