Fireball (Donkey Kong)
Fire (also known as a Fireball and a "trouble bug"[1]) was the first generic enemy in a Mario game. Despite their last of three names, they are not insects, but living embodiments of fire similar to the Podoboos from Super Mario Bros.
Fire appears in three of the four stages in Donkey Kong. In the ramp and conveyor belt stages, Fire emerges from the oil drums. They chase Mario and one touch would cause him to lose a life. They could be destroyed with a Hammer. In the rivet stage, they are replaced by Firefoxes.
They also appear in Mario vs. Donkey Kong 2: March of the Minis in the final boss fight with Donkey Kong, on the roof and the basement levels. Fire also appears in Super Smash Bros. Brawl on the 75m stage. On that stage, Fire can damage the fighters by touching them. Each hit does 10% damage and moderate knockback.
