Amphysist is a tall humanoid alien. He's a purple creature with one eye. He have very thin legs and very long arms which nearly touch the ground in the rest. He have 4 long fingers. He wears a suit similar to Two-Face.

He has the ability to become intangibility and invisibility. He doesn't speak much, he prefers a quick attack with his sharp talons. He's a very loyal servant to Animo and follows every order without questioning. He can also create lesser clones of himself which he can use against his enemies.


He was one of the first living creatures created by The Engineer. All the earlier creations were liveless things. He was trained to become an assassin and sent to steal the Dracosian Dimensional Engine. He was responsible for the death of most of the Dracosian scientists. When confronted by Ben, He cloned himself and attacked them. His clones have the others the chance to escape.
