King Bill

King Bill appeared in 2009 video game called New Super Mario Bros. Wii. King Bills are a variant of Bullet Bill that first appears in New Super Mario Bros. Wii. They are gray, with a "goofy" grin as opposed to the Banzai Bill's menacing grin, and are the largest known Bullet Bills in the Mario franchise, dwarfing the second largest Bullet Bills, Banzai Bills, where they take up nearly the entire screen. Unlike the rest of the varieties of Bullet Bills, King Bills do not have their respective blaster shown onscreen, meaning that they are always fired from offscreen areas. When the King Bill spawns, players can see the King Bill's eyes following their character's movements.
