Character: king bob-omb
King Bob-omb (formerly known as the Big Bob-omb) is the king of the Bob-ombs who debuted in Super Mario 64, being the first boss fought in that game and its remake. Guarding the Power Star, which Bowser entrusted him with, he does not give it up without fighting the player. After his debut, King Bob-omb became a recurring boss in later games, specifically spinoff games such as Mario Party 9 and Mario & Luigi: Paper Jam. King Bob-omb, like other certain bosses, takes pride in his royal status.
