Tim Dean

From Ben10versepedia

Tim Dean, from the episode "Super Alien Hero Buddy Adventures", is the writer of a show-within-a-show of the same name, a cartoony parody of Ben's alien forms. Ben, angry at the writer for ripping off his aliens, initially believes Dean is the one causing all the weird things that were happening at the theme park, Planetary Studios. Ben later discovers it's Kane North, the twin brother of Abel North causing the trouble, who wanted revenge because Dean stole his show idea from Kane.
