King Boo is a minor antagonist in The Super Mario Bros. Movie seen having a cameo during the wedding scene.

Biography[]

He is the monarch of the Boos, and is seen in the background of the wedding between Bowser and Peach. He presumably flees upon King Bob-omb's fuse being lit.

Triva[]

• Interestingly, he is the only attendant of the wedding who didn't attack Peach after she froze Bowser (with the exception of King Bomb-Omb, as he didn't attack Peach because he was sleeping). If there'll be a movie based on he game "Luigi's Mansion", it might be foreshadowing of his possible betrayal of Bowser.
