Ectoplaz as a 750 year-old triangulum. While lacking any special abilities, he is in possesion of a flame sword- a weapon useful for burning enemies .
Ectoplaz is a bitter enemy of Kaos.
Ectoplaz was born into Dimension 816, the dimension of darkness, but he and his family (consisting of his mother, Octoplaz, and James), managed to escape, narrowly avoiding being eaten by Kaos. His father had stayed behind, in an act of self-sacrifice.
