Nocturnus Clan

They are a rival clan of echindas who used to be from Sonic's world 4,000 years ago but in their moment of triumph, a dark force wrenched them from their home and into the Twilight Cage. The technology they use to do battle with is very advanced. So advanced they even have Gizoids, which they created anyways. When they attack, they can usually take some of your HP away from you.
