Ben is the wielder of the Omnitrix and also the Society's heavy hitter for intense battle
Benjamin Kirby Tennyson was an average ten-year-old kid, until he found the Omnitrix, an exceedingly strong and powerful watch-like device that allowed him to turn into ten different alien species. Though initially immature and clumsy, he grew as a true hero, who, by the time he was sixteen, had become famous in not only his hometown of Bellwood, but on Earth and beyond, as well as a member of the Plumbers.
Ben's physical appearance has evolved throughout the series from a ten-year-old to a fifteen and sixteen-year-old teenager. However, he retains some recurring characteristics. He has short brown hair, green eyes, pale skin, and he's quite skinny for his age (though his various future selves are portrayed as quite muscular), though he shows a lot of muscle definition due to being athletic. In the original series, his usual clothes consisted of a black-striped, white T-shirt with short sleeves, deep green cargo pants, and black and white sneakers. Starting with Alien Force, he starts wearing a black T-shirt, blue skinny jeans and a white-stripped green jacket with the number 10 on it, clothes he retains in Ben 10: Ultimate Alien. Ben wears the Omnitrix and Ultimatrix on his left wrist in a watch-like manner. Like all the other main characters, his physical appearance hasn't changed much.
