Banzai Bill

Banzai Bills are recurring enemies in the Mario series. They are an extremely large variety of Bullet Bills that first appeared in Super Mario World. Although they seem difficult to defeat, they can be defeated simply by jumping on it.

In Super Smash Flash 2
Banzai Bill is an hazard in Peach's Castle. It may come flying toward the castle from the any side of the stage, inflicting damage on contact. Once it reaches its destinations, it plunges onto the castle, creating a large explosion. If a character gets caught in the explosion, massive damage will be inflicted on him/her and he/she will be KO'ed without a way to recover. However, Banzai Bills can be easily avoided.
