Ben will find himself facing his toughest challenge yet, when Vilgax sends out three alien bounty hunters: the crustacean-like Kraab, the mechanical assassin Sixsix, and the mysterious Tetrax (credited as Hoverboard) - to recover the Omnitrix. He soon learns that there's more than one way to defeat an enemy, and that things are not always what they seem.
