Thelxe

Thelxe (セルクス) is a Voxai. He was one of the "Overmind's elite protectors", and probably one of the few who willingly supported their despotic ambitions. He confronted Thebes at the entrance to Colony Alpha's teleport gate. After being knocked out by Sonic's group, Thebes extracted the teleport code from Thelxe's mind and imprinted it on Sonic's. Thebes stayed behind on Colony Beta, to "keep his mind on" Thelxe.
