He had the same plot just like in the movie until SpongeBob and his friends traveled to the surface to stop him and foiled his plans.
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 descend into a 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, unlike in The SpongeBob SquarePants Movie, where it took only SpongeBob and Patrick to defeat Plankton.
The following people voiced Burger-Beard in the non-English versions.
