Ben Tennyson (voiced by Tara Strong in the original series) is the protagonist of the animated TV show Ben 10 and its spin-offs.  After he discovers the Omnitrix, Ben is able to transform into different aliens.  Originally a bit selfish and immature when he first discovers the Omnitrix, Ben develops good leadership skills over the years and becomes a true hero.  In the original series, Ben wears green cargo pants, a black and whtie t-shirt, and black and white shoes.  In Ben 10: Alien Force, and older Ben wears blue jeans, a black t-shirt, a green jacket, and black and white canvas shoes.  If you are worried about a toy Omnitrix fitting your wrist, a black and green watch is a good option.
