First Appearance The More Things Change Part 1(LEGION)

Ben 10 is a hero in BEN 10:LEGION. He first appeared in The More Things Change Part 1(LEGION). He is a Human from the planet Earth.


He is tall with bright green eyes and deep brown hair.

He is seen wearing an Green Jacket,brown Parka pants and black'n'white shoes.


Over the years, Ben has displayed good leadership skills, as well as the ability to adapt his attitude to a situation, becoming serious when it's called for. He became more mature, responsible and sensible. He's kind-hearted, willing to sacrifice even his own life for others. His idealistic views and unwillingness to compromise his values – aspects condemned by Azmuth, yet commended by others – sometimes drive him to act against reason, such as helping his enemies if they need it (most remarkably Vilgax). Professor Paradox has praised Ben's good nature, going so far as to say he had the gift to make the right choices at the right moments.

However, when Ben fails to save someone, or if someone gets hurt because of his failures, he becomes angry and much more violent. Perhaps the most notable of these instances is when Kevin willingly mutated himself to succeed where Ben had failed and stop Aggregor, Ben was set on killing Kevin, even fighting Gwen when she refused to help him. He also threatened to hunt down and destroy the Forever Knights once making Driscoll promise to cease the hunting of aliens.

Though often stated to be silly or unintelligent because of his immaturity, Ben is cunning and resourceful when needed, quickly adapting when the Omnitrix doesn't provide him with the alien he wanted.

Later on, Ben starts thinking of himself as more of a superhero than a Plumber, often remarking that he's not a cop, but a superhero.[5] Although he once again became cocky, he retained his selfless and heroic nature.

Powers and Abilities

He has good qualities as a Leader,he has good intuition,agility,Hand-to-Hand Combat and has a very high IQ.


He can sometimes be arrogant and not do the right thing,his fear of clowns and squids makes him vulnerable at saving his loved ones.

He can't fight anymore if his family/friends are in danger.

His love for Smoothies and Chili Fries can make him fight to death with someone who messes with them.

If someone angers he well enough he'll soon be trying to kill the person as a result,like in The Ultimate Enemy where he almost killed Vilgax in Ultimate Alien.
