He was an ordinary 10-year-old boy until he found the Omnitrix, a powerful watch-like device that allowed him to turn into 10 different aliens. Though initially immature and clumsy, Ben grew to be a true hero. He has unkempt brown hair, green eyes, fair skin, and he is quite skinny for his age, though he shows a lot of muscle definition due to being athletic. Ben's usual clothes consisted of a black-striped, white shirt with short sleeves, military green cargo pants with side pockets with a black belt hidden under his shirt, and black and white sneakers with black stripes. Ben wore the original Omnitrix on his left wrist. Initially cocky, childish, and selfish, Ben's immaturity and attention-seeking behavior often led him to joke around, regardless of the situation, which landed him in trouble with adults. When he was 10 years old, he often used the Omnitrix improperly in order to benefit himself instead of actually helping others, such as using Grey Matter to search cereal boxes for a gold Sumo Slammer card. His allies often criticized his attitude, unaware of the fact that he used humor to mask his fears. It was also implied that, on some level, Ben helped people to get rewards and for the thrill of being a hero, rather than because it was the right thing to do. Despite some childish attitude, Ben was heroic, caring and generally good-natured, always willing to save others at any time even at the risk of himself. In spite of this good nature, heroism, and his moments of maturity, Ben could occasionally get carried away when it came to fame and recognition.This led him to act rather arrogantly and recklessly, and occasionally made dire mistakes and alienated his loved ones. However, he was quick to realize his mistakes and is quick to take responsibility and knew not to take things too far. Originally, Ben was a 10-year-old boy who grew up in Bellwood. He was unpopular to his classmates and was often bullied by two boys named Cash and JT However, his life changed when he went on summer vacation with his grandfather, Max and his cousin, Gwen. That evening, they stopped to camp in the woods. Ben witnessed the crash of a strange capsule from space, which happened to contain the Omnitrix, a powerful watch-like device. As soon as Ben found the device, it firmly affixed itself onto Ben's left wrist, and Ben was unable to remove it. At first scared, Ben soon discovered that using the Omnitrix, he was now able to transform into ten super-powered alien creatures and began to use the device to become a superhero. Though he occasionally arrested ordinary criminals, he was quickly led to also fight super-villains, starting with Dr. Animo, Kevin 11, and ultimately, Vilgax, a vicious and evil alien warlord who would stop at nothing to get the Omnitrix for himself. Despite being very immature and occasionally using the Omnitrix for minor selfish purposes, Ben proved to be a valuable wearer for the Omnitrix, defeating Vilgax and saving people several times.
