Most of the original characters and concepts in Knuckles Chaotix would stay in limbo until the release of Sonic Heroes in 2003.

Sega has been hesitant to re-release Knuckles Chaotix, as the only time it’s happened was on Game Tap in the mid-2000s.

Knuckles Chaotix famously features as a Sonic game without Sonic or Tails, but some of the characters like Mighty the Armadillo actually premiered in a previous game SegaSonic the Hedgehog.
