At the end of The SpongeBob Movie: Sponge Out of Water, he was immortalized as an artist's rendition, which is known as "Painty the Pirate."
His evil plot in the movie was to steal the Krabby Patty Secret Formula so he can add it to the Magic Book that he possesses. In the magic, every evil plan he writes down comes true and the secret recipe completes the book in order for this to happen. SpongeBob and his friends traveled to the surface to stop him and rewrite the story.
Though his actions motivated by greed and appeared not as notorious as Plankton in the first film, Burger Beard is arguably the most dangerous (if not cataclysmic) and toughest antagonist of all SpongeBob SquarePants villains, as he easily let Bikini Bottom descent into post-apocalypse state by stealing the Krabby Patty recipe through his magic book, have no qualms of Bikini Bottomites' fate, and it took all superpowered main casts alongside superpowered Plankton to finally defeat him.
