Kaeden is the primary antagonist of Daxter. He was a very large metal bug (a subspecies of metal head) capable of transforming into a human, and was tasked with going into Haven City and commanding the invasion of Metal Bug forces. As such, one of his primary objectives as a human was to shut down metal bug extermination shops, such as Osmo's Kridder Ridder extermination company, making him a very antagonistic figure towards Osmo and Daxter. He ultimately served as the game's final boss.
