Kenny 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, 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.
Ken's cameo in Omniverse.
Kenny bears a striking resemblance to his father when he was his age. His clothes are modeled after his fathers 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. But his skin tone is slightly tanned which he inherited from Kai.

According to the pop-up edition of Ben 10, Ben 10,000 used his smartest aliens to create Ken's Omnitrix.
