Details

Benjamin Kirby "Ben" Tennyson was a normal ten-year-old kid until he found the Omnitrix, a powerful watch-like device that allowed him to turn into ten different aliens. Though initially immature and clumsy, Ben grew to be a true hero. By the time he was sixteen, he had become famous in not only his hometown of Bellwood but on Earth and beyond. Ben has also been deputized by the Plumbers and gained more aliens as time progressed.

Appearance

Ben's physical appearance has changed throughout the series from a ten-year-old to a sixteen-year-old. However, he retains some recurring characteristics. He has shaggy brown hair, green eyes, pale skin, and he's quite skinny for his age, though he shows a lot of muscle definition due to being athletic.

In Galactic Adventures, he wears his Alien Force and Ultimate Alien attire.

Personality

Initially cocky, childish, and arrogant, Ben's immaturity and attention-seeking behavior often led him to joke around, regardless of the situation. His allies often criticized his attitude, unaware of the fact that he used humor to mask his fears. Despite some childish attitude, he was heroic, caring and generally good-natured, always willing to save others at any time.

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. He's kind-hearted, willing to sacrifice even his own life for others. His idealistic views and unwillingness to compromise his values – aspects condemned by Azmuth, yet commended by others – sometimes drive him to act against reason, such as helping his enemies if they need it (most remarkably Vilgax). 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.

Though often stated to be silly or unintelligent because of his immaturity, Ben is cunning and resourceful when needed, quickly adapting when the Omnitrix doesn't provide him with the alien he wanted.

Later on, Ben starts thinking of himself as more of a superhero than a Plumber, often remarking that he's not a cop, but a superhero. Although he once again became cocky, he retained his selfless and heroic nature.

However, after witnessing the creation of a new universe and realising just how small part of the huge multiverse he is, Ben decides to leave his fame behind and go for an interstellar journey. That realisation causes him to take things seriously. Inspite of his newfound maturity and seriousness he still likes to joke around and tease people, especially Gwen, Kevin, Rook and Kai.

Events of Galactic Adventures

After witnessing the creation of a new universe by the Contumelia, Ben is inspired to go on a journey to explore his own universe. Ben tags along Kevin and Rook for his journey. Gwen who has been awarded a holiday from her University due to her excellent achievements also joins them on this epic journey. However, Rook gets a call from his father who wants him back for the harvest. Rook bids the group farewell but promises to join them later. The group tell him that they'll pick him up from Revonnah.
