The Beard is the titular antagonist of the popular parody game known as Castle Crashing: The Beard and is based loosely on Tom Fulp, who promised not to shave his beard in real life until he completed Castle Crashing - thus in this comical world Tom's beard has gained a life of its own and become a destructive monster intent on destroying pretty much everything in its path.

Manifesting as a gigantic Tom Fulp head with an impossibly large beard the monstrous Beard attacks with an array of powerful assaults as it battles the player across multiple worlds, the game being in essence one giant boss fight against the seemingly unstoppable Beard.
