Ben Tennyson

Verified Timeline

Lore & Background

The story begins when ten-year-old Ben finds the Omnitrix in a crashed pod in the woods during a summer vacation. 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. He often used the Omnitrix improperly to benefit himself instead of actually helping others, and it was implied that, on some level, he helped people for rewards and the thrill of being a hero, rather than because it was the right thing to do. Despite this, Ben was heroic, caring, and generally good-natured, always willing to save others at any time even at the risk of himself. Over the years, Ben has displayed good leadership skills, as well as the ability to adapt his attitude to a situation, becoming serious when it's called for. He became more mature, responsible, and sensible, continuing to be kind-hearted and willing to lay down his own life for others. Professor Paradox has praised Ben's good nature, going so far as to say he had the gift to make the right choices at the right moments, and even Azmuth states that Ben ultimately always does the right thing. However, even as a teen, Ben still displays some of his negative childish traits at times, which usually comes to light when Ben gets too caught up with fame much to the annoyance of Gwen and Kevin. Ben also has a violent, aggressive side: when Ben fails to save someone, is worried about the well-being of his loved ones, or if people get hurt because of his failure, he becomes angry and lashes out, even at people he cares about. Ben confessed to Max that he felt guilty for letting fame get into his head and claimed that he was trying to act more mature for once.

In Their Own Story

The Omnitrix dial clicks into place on Ben's wrist as the alien creature looms overhead. Dust swirls in the humid air of the swamp, masking the approach of danger. With a deep breath, he slams his hand down, the green light engulfing his small frame until only the silhouette of a new form remains ready to strike.
