More information will come as the story progresses.
Benjamin "Ben" Kirby Tennyson is a 10-year-old kid who found a mysterious watch-like device called the Omnitrix.
Ben is a Caucasian 10-year-old boy with light brown messy hair and green eyes. He is short for his age but is fit. Ben often wears a white top with a big green stripe and a small black stripe across it. He wears black shorts with pockets and green converse-style sneakers with black squares on the tongue. He has white socks under his shoes. Ben wears the Omnitrix on his left wrist.
Ben is cocky and childish. He often messes around and makes constant jokes. To most villains his jokes are an annoyance but Ben uses humour to hide the fear of fighting criminals and aliens, he is only 10. When Ben is in trouble he relies on his alien forms and often misuses the Omnitrix because of this reason. Despite all this Ben wants to help people. That is his true goal.
Ben is also quite intelligent but often decides that using brute force or being stupid will be the more fun way to do things so he chooses that. If Ben did need to outsmart someone he is capable. He also often gets caught up the situation he is in and ignores what is going on outside. In battles he often destroys property to stop the bad guy and doesn't think what is is doing outside the fight, other than protecting civilians, which he might miss unless he looks directly at them. Ben's attention span can be short when he is board.
Ben likes to play sports. He has played soccer, baseball and mixed martial arts. He regularly goes for swims in the local swimming pool as well. Ben plays video games often, his favourite being Sumo Slammers, which he collects the TCG game for and plays. He is also an avid viewer of movies with his favourite being action and spy. His favourite food is chili fries and likes to drink smoothies.
Ben has huge fear of clowns.
Ben does not have any super powers, although though he does have a photographic memory. He is also naturally talented at skateboarding and anything alike.
When the Omnitrix times out, Ben is left powerless and doesn't have the skill to dodge a superpowered enemy's attack. Ben only has a very limited amount of knowledge on the Omnitrix, so he constantly doesn't know how to use it properly and often gets a wrong transformation. He often doesn't know some aliens' powers. Some weaknesses are included in the Personality Section.
