Shrek the Motherfucking Ogrelord

Shrek (sometimes referred to as Shrek the Ogrelord) is a character who appears in The SpongeBob SquarePants Movie series. Viacom was able to secure the rights to Shrek after Dreamworks was destroyed by Comcast; following this, Shrek was placed in the majority of Paramount Animation's movies.

Role
In Battle of the Fireworks!, Shrek is a member of the Illuminati, and recruits Vinesauce Vinny, Jontron, and videogamedunkey to create a SpongeBob episode. The characters crash onto the planet, and the team decides to save the world. In the final battle, Shrek fights AHE, but unsurprisingly does not change form at all.

In The Cloonbob Saga, Shrek (referred to as Swamp Owner #1 in the credits) has bought a swamp on Earth, and is pursued by George Clooney for giving his musical a negative review. George Clooney fights Shrek, and believes he has won as he leaves the swamp; however, Shrek gets back up and tells the audience that "It's never ogre!".

In The Great Regime, Batman, Waluigi and Wario encounter Shrek in his new swamp. They ask him if he wants to join their team; Shrek initially declines, stating that he's a family man now. Wario plays "All-Star" on a boombox, prompting Shrek to let out a mighty ogre roar. He remarks that this is the best he's felt in ages, and joins the team.

Shrek appears in The Squog Show episode "All That Glitters is Squog", where he attempts to teach Squog the power of onions. Squog fails to understand, so Shrek angrily kicks him out of his swamp.
