Bull's-Eye Bill

Bull's-Eye Bill appeared in 1988 video game called Super Mario Bros. 3. Bull's-Eye Bills, formerly known as Missile Bills, are heat-seeking variants of Bullet Bills typically fired from Bull's-Eye Blasters. They attack by homing in on the player. Prior to New Super Mario Bros. Wii 's introduction of the current Search Killer (サーチキラー), which eventually became known in English as Bull's-Eye Bill, earlier games gave the homing abilities to normal Bullet Bills or their behavioral or color variations, as various sources treat them as. Following the introduction of their modern iteration, whenever Bullet Bills do not home in on Mario, Bull's-Eye Bills usually appear along them for that purpose.
