The Corn Colossus is the guardian of the Temple of Juatchadoon and the secondary antagonist of the Phineas and Ferb episode, "Phineas and Ferb and the Temple of Juatchadoon", second only to Doofenshmirtz from 1914.
The Corn Colossus was first seen when Ohio Flynn, Rhode Island Fletcher, Candace from 1914 and Isabella from 1914 arrived at his throne room at the deepest inside of the temple. They were soon captured by Doofenshmirtz from 1914, soon freeing Isabella due to a deal they made.
Some more explanation and another trap later, Doofenshmirtz obtained the amulet and with it, he activated the colossus just before Perry from 1914 arrived. The colossus still managed to wake up and started to follow the team and the recently saved Isabella and New Hampshire.
Once they were at the top, the colossus was shown to still be going after them despite being on fire from one of the traps from earlier. Then Perry's hat arrived with the amulet, and the team used it to make the colossus explode, killing him in the process.
The Corn Colossus is a giant yellow maya statue-like creature. He might also have been made of corn itself, since he exploded into popcorn with the amulet.
