Ken Yamamoto-Tennyson

Kenneth Maxwell Yamamoto-Tennyson is a main protagonist in the series Ben & Ken: The Adventures.

Personality
Ken is very much like his father was when he was 10 years old. Especially when you compare his and Ben's behaviors. One example of this was his immediate friendship with fellow troublemaker Devlin Levin (Like Ben & Kevin). Like Ben, Ken had access to only 10 alien forms in the beginning with his Omnitrix, but he later gained access to more. He was also shown to be slightly more resourceful than his father was by his use of Grey Matter to hack the Omnitrix and unlock the Master Control.

Appearance
Ken has a slight appearance to his father but keeps his mother's hair colour. He wears a green top that show the number '10' at the back, referring to his ten aliens. He also has UAF Ben's jeans and the shape of his legs.
