Grandpa Max and Ben Tennyson in “Unfinished Business”

The Mask of Ah Puch is the guide to the sword of Ekchuah. A Plumber's searched for it for decades without any luck.

Ekchuah? What kind of alien is that?

Not alien. Mayan. Echtua was the Mayan god of war. His sword was rumored to have leveled cities with just one swipe.

Ha! Sounds like just the kind o' thing the world's most powerful ten-year-old boy should have.

This is no toy, Benjamin. Whoever controls the sword controls the destiny of Mankind, and I will not let it fall into the wrong hands.
