He is a Cactus Guard who is sworn by an oath to protect the Desert Villagers, He is the pedigree lower than an iron golem.

BATTLE CACTUS!!!

*For the Contest: He was once a normal, Boring cactus who was just sat there in the desert all day. However this all changed when he was exposed to Mega Xp orbs when a normal player was walking by who had half a heart left and completely drained hunger, and had come into contact with the "Ordinary Cactus." The Player dropped a whopping 9001 Xp when it died, which caused the Cactus to mutate and Become a super powerful, Living, breathing and Blocky Cactus. Which Ends the story of How this cactus Became it's super powerful self.
