Believing himself to be the king of the Machine Empire, Tommy prepares to face Jason in the arena. The other Rangers try to join his side, but are unable to, until they get help from an unlikely source, their old enemies, who are now the enemy of their new enemies. Even if the spell on Tommy can be broken, getting out of the monster-filled arena safely will require the aid of an even more unlikely source, Earth's self-proclaimed "greatest warriors", Bulk & Skull, who join forces with a captive alien warrior seeking revenge on Prince Gasket for conquering his home planet of Horath.
