Kenneth Tennyson

Ken Tennyson is the cousin of Ben Tennyson and Gwen Tennyson's older brother that they look up to. Ben 10,000 may have named his son after his cousin for that reason.In the future, Ken Tenneson is a 10 year old boy. At the Hatchery, Ken almost became a DNAlien. Ben just managed to remove the Xenocyte while he was inside the Omnitrix.

Trivia

 * He is a second generation Human/Anodite hybrid like his little sister, Gwen. It is unknown if he possesses the "Spark" (the ability to sense & control mana), however it is unlikely.


 * He is hardly ever mentioned before or after the episode, Max Out.


 * He appears to be the namesake of Kenny Tennyson, the future son of Ben 10,000.
