First Appearance Captain Omnitrix

Captain Omnitrix is the main protagonist of Ben 10: Omnitrix Legend. He is covered in mystery and nothing is really know about him.


Captain Omnitrix wears a uniform similar to Eon from Ultimate Alien, except in green. He wears a black mask like many other superheroes do. He wears a green helmet with the Omnitrix symbol on it. He also wears an Omnitrix symbol on his chest. He wears a green cape also.


Captain Omnitrix is very secretive about himself. He is also very tough and serious. He always seems to work alone and rrely talks in public.

and Abilities

Captain Omnitrix is a great hand to hand combat fighter. He appears to be very strong, but not as strong as a Tetramand; just stronger than an average human. He can skillfully wield weapons in either hand and he is a great swords fighter.

He can alter his DNA as he has an Omnitrix symbol on his chest.

He appears to be very intelligent since he seems to know very much about Galvan Prime and Galvan Mark II.

Other than that he has no special abilities since he is human.


Whenever the Omnitrix times out he is left powerless.


  • He built the Omnitrix he created with help from a Galvan.
