Shed 10 is Ben's new dog. His name describes him. He sheds alot. So after a while Ben got tired of having to clean up his mess. So he sold him to someone else. That someone else was Zedo! Zedo used the DNA of Ben that was on him to take over Ben's body but Shed 10 got mad and ripped Zedo's lair apart. Then it exploded. Zedo was very injured after that, but he didn't die.
