Kenny bears a striking resemblance to his father when he was his age. His clothes are modeled after his father's. These include a white T-shirt with black accents and borders at the sleeves, and his trademark baggy green cargo pants. Kenny's eye color is even the same as Ben's. His skin tone is slightly tanned, a trait which he inherited from Kai.
Kenny is very much like his father was when he was 10 years old. One example of this was his immediate friendship with fellow troublemaker Devlin Levin.
Ken was also shown to be slightly more intelligent and resourceful than his father was at the same age, as he used Grey Matter to hack his Omnitrix and unlock the Master Control, something that his father's Galvan form couldn't do or even think of.
In Ken 10, Ken has his 10th birthday party and receives three gifts, from his father an Omnitrix Replica, from his aunt a Stone Dog and from his great-grandfather a hoverboard. Kenny, initially ecstatic about the Omnitrix, is soon disappointed with his selection of aliens, further more even though Kenny is allowed to join his father when he's alien hunting Ben's years of experience and efficiency leaves Kenny with not getting any kicks in.
Going out flying with the Hover board Kenny runs into Devlin, a young street urchin who befriends him and consoles him about his father issues. Later that night while his HQ is being broken into Ben initially decides to allow his son to join in against whatever foe has broken in, until that is he discovers the one responsible to be none other than his old foe Kevin Levin and grounds Ken to his room.
While the two are fighting Ken uses Grey Matter to sneak out of his room, eventually arriving in the empty Null Void Chamber just as Kevin flees. Meeting up with Devlin in the morning he proposes that they try to deduce what is wrong with the Null Void Projector in order to prove themselves to Ben. Having deduced and located the projector Ken and Devlin break in only for Devlin to reveal that he was the one who Ben was fighting.
Furthermore, he releases his father, the real Kevin 11,000, who proceeds to beat on the newly arrived Ben, not caring about his son. Ken is able to use Grey Matter to crack the Omnitrix master control and aid his father alongside Devlin to fight Kevin. Getting wounded in the crossfire Ken's injury enrages Ben to the point that he beats Kevin into the ground and captures him in a Containment capsule.
With Kevin now in custody once more, Devlin comes to live at the Tennyson Family residence.
