Leech (X-Men: Evolution)

Dorian lived with his mother, Mrs Leech. After mutants were revealed to the world, he was quickly identified as a mutant for his unusual appearance, although his mother protested that he was normal. He would occasionally get headaches. When a group of humans (led by Duncan Matthews) clashed with several mutants (including Spyke and the X-Men), Dorian was present at the scene. After suffering a severe headache, his mutant powers activated for the first time, and he completely nullified all the energy in the area: the humans' weapons and the mutants' powers. His mother was angry that he had been revealed as a mutant, and demanded how he could live a normal life. Spyke, then living with the Morlocks, sadly replied that he could not.

Rogue later absorbed Dorian's powers during the attack against Apocalypse, using them to shut down his Eye of Ages and trap him inside.
