| This article is about Gwen Tennyson's brother. For the son of Ben 10,000, see Ken Tennyson (Future). |
Kenneth "Ken" Tennyson is the older cousin of Ben, Gwen's older brother, and son of Frank and Natalie Tennyson. Both Ben and Gwen looked up to him. Ken Tennyson was never mentioned or even alluded to during the run of the original series.
Appearance
Ken is a tall young adult with green eyes and red hair, resembling his sister, Gwen. He wears a blue jacket and a white shirt underneath, he also has brown pants and white shoes with black accents.
History
In his first appearance he was abducted by DNAliens after they sabotaged his ride, the "Awesomobile" in order to flush Max Tennyson out of hiding, as he was slowing down their operations on Earth.
Ken's failure to regularly contact his parents led to his disappearance coming to the attention of his younger sister, Gwen, and cousin, Ben Tennyson. After being traced to his last known location, Ken's trail was first followed by his Grandpa Max, who tracked him down to an DNAlien Hatchery. Ken, having previously known nothing about his grandfather's former life as a Plumber, was questioned by a DNAlien for any information, but Ken knowing nothing, the DNAlien, having already known that Ken knew nothing, placed a Xenocyte on Ken's face, which began to convert him into a DNAlien.
When Max infiltrates the Hatchery to free Ken, Ken was already partially converted into a DNAlien and attacked his own grandfather for the Highbreed. When Ben, Gwen, and Kevin infiltrated the Hatchery having followed Max's trail, they're ambushed by a swarm of DNAliens, Ken among them. When Gwen sees her brother almost completely changed into a DNAlien, she restrains him and prevents him from being attacked by Ben and Kevin--they having not recognized him yet.
At Ben's confirmation, Ben and the Omnitrix together restored Ken to his human form. Along side the others, Ken aids them in rescuing Max, who reveals that he'd been keeping up-to-date with all of their experiences since his disappearance. While Max goes to shut down the Hatchery, Ken helps the others destroy the DNAliens shipment of Xenocyte eggs.
When Max Tennyson seemingly sacrificed himself to bring down the Highbreed in charge of the operation with a makeshift Null Void grenade, Ken Tennyson was present at his grandfather's apparent death.
