Banzai Bill (マグナムキラー, Magunamu Kirā, Magnum Killer in Japanese versions) is a character/weapon that is part of the Mushroom Kingdom.
Banzai Bills appear as golden missiles which are fired by Master Hand. Each Banzai Bill does 5% damage. Master Hand will fire one set of two Bills if above 100 HP and three sets if below.
In the stage Princess Peach's Castle, Banzai Bill appears from the sky and starts flying towards the castle. Banzai Bill will then land into the castle. The location where Banzai Bill lands is random. Banzai Bill will then start to flash which indicates that he is about to explode. When Banzai Bill explodes, any character in the blast radius will take heavy damage, and be suffer extreme knock-back. Banzai Bill's explosion usually results in a One-hit KO. Any character who makes contact with Banzai Bill before he explodes will take damage.
Banzai Bills also appear occasionally in the background of the stage Yoshi's Island with their original 2D appearance.
The Banzai Bill trophy erroneously refers to it as a Bullet Bill (Bullet Bills would only appear properly in Brawl). The Japanese version, however, correctly labels it "Magnum Killer" (regular Bullet Bills are known only as "Killer" in Japan).
- Bullet Bills are shot out of cannons and fly on straight paths. In great numbers they're a nightmare; while Mario can stop most with a single jump, the giant one, Banzai Bill, is much tougher to avoid. In Super Smash Bros. Melee, only Banzai Bills can be seen. They burrow into Princess Peach's castle and then detonate with immense power.
- Super Mario World [8/91]
Banzai Bill appears in the background of Yoshi's Island, like in Super Smash Bros. Melee.
Banzai Bills appear as enemies in Smash Run most of them chase the characters in an attempt to make physical contact with them after a while they will speed and fly in a single direction and can get stuck in the ground if not defeated in time they will explode dealing heavy damage and knockback.
They also appear as enemies in Smash Tour.
This giant bullety menace from the Mario series might look tough, but one jump is typically all it takes to deal with it! In Smash Tour, a Banzai Bill will sometimes charge into a space and explode, destroying any items there. Players caught in the blast will be launched to another space.
