Ben wears a black and green shirt with the number 10 on the top left corner, green cargo shorts, blue boxer shorts, black low profile sneakers along with white tube socks. His eyes are green, and his hair is brown.
Ben is childish and cocky, and likes to have fun. He doesn't like to do lots of cleaning. His reckless behavior sometimes leads to consequences, such as Ben awakening the Hydromanders when splashing on Niagara Falls as Cannonbolt. Besides his childish behavior, Ben is heroic and caring, willing to help and save anyone in need.
Powers and Abilities
The Omnitrix: A powerful device that allows Ben to transform into 10 different aliens with a variety of different skills and powers.
Whenever the Omnitrix times out, Ben is left powerless unless he switches into a new alien form. In addition to gaining the selected alien's powers, he gains its weaknesses. The Omnitrix also mistransforms at times, sometimes choosing an alien not fit for the situation.
