The Mayan god of death and protector of the Sword of Ekchuah, , Ah Puch is even larger than Fourarms (about twice as large) and strong enough to send Fourarms flying with his tongue alone. He appeared in "Ultimate Weapon" He first appeared attacking the Forever Knights as they attempted to steal the sword. He was largely winning against them, but attacked Ben and company when they tried to reach the sword. He was defeated by them, and left in the temple as it collapsed; what became of him is unknown. Though he attacked Ben and the others, he only did so to defend the sword. His image was used for the Mask of Ah Puch , the only thing that could lead one to the sword.
