Benjamin Kirby Tennyson is the main protagonist of the Ben 10 series. He was a normal 10-year-old kid until he came across a watch-like device known as the Omnitrix, which allowed him to turn into 10 different aliens. Though he's immature at times, he has become a famous alien-fighting hero by age 16. His first appearance in the School Daze saga was in the 4th movie "Road to the Omniverse".
Ben is known to be childish, cocky, and arrogant at times. His immaturity often leads him to joke around, regardless of the situation. His teammates often criticized him for his behavior, while unaware that he uses humor to hide his fears. Despite this, he is heroic, caring, and generally good-natured. He is willing to save others at any time. Ben has also shown some good leadership skills, as well as having the ability to adapt his attitude to a situation, becoming serious when needed. During these situations, Ben is more mature, responsible and sensible than how he normally is. However, Ben can get angry and more violent if he were to fail to save someone. Nonetheless, Ben is still a brave soul.
Road to the Omniverse Edit
When he was 10, Ben, along with Gwen, took out Eon using the Omnitrix and Magic. After being defeated, Grandpa Max sends Eon to the Null Void with a Null-Void projector. Before getting sent away, however, Eon states that he will return in 6 years. 6 Years Later, Ben, now 16 years old, was on a road-trip with Gwen, Kevin, and Grandpa Max. They were minding their own business, when suddenly, they ran into Eon, who had escaped from the Null Void. He tries to take the Omnitrix, but to no avail. But he manages to destroy the Null Void Projector before leaving. This forces Max to find some old fellow plumbers to help him take down Eon. During their trip, Kevin decides to take Gwen to a dog show for Valentine's Day, considering that she loves dogs. On the way, Max accidentally rear-ends someone else's car. The owner turns out to be Fredrick Jones, the host of the dog show with his dog Ellie(NOTE: The dog show part takes place around the same time as the Family Guy episode "Boy (Dog) Meets Girl (Dog)"). Once Frederick recognizes Ben Tennyson, he decides to let it slide. He also offers them free access to the dog show. While Max looks for one of the plumbers, Ben and his friends watch the dog show. After Brian won, they were shocked to learn that the breeding was public. Then, Eon returns and turns everyone he touched into Senior-Citizen-like Zombies. Ben, Gwen, and Kevin manage to rescue Stewie and Brian and meet Max at the Rust Bucket. They then learn that Carter is one of the 2 plumbers the team is searching for. They spend the night at his mansion before heading to Massachusetts to find the second plumber, who is Caillou's grandfather Hadley, who was visiting at the time. Hadley sends a note to Tom and Caillou, telling them to meet at his house. Once they arrive, they head to Bellwood and spend a week there. During the week, they go to the movies, Ikea, the Stadium Theatre, a variety of restaurants, and Froyo World. Eventually, Ben and his team head to Eon's hideout and successfully defeat him after a rough battle. Afterwards, they all part ways.
Ben has fair skin, green eyes, and shaggy brown hair. He is quite skinny for his age, though he shows a lot of muscle definition due to being athletic. Ben wears the Omnitrix on his left wrist. He is shown wearing 2 different outfits.
