Banzai Bill (マグナムキラー, Magnum Killer) is a character/weapon that is part of the Mario universe. They are larger versions of Bullet Bills but without white arms and hands, while having a mouth with a shark-like smile.
Banzai Bills first appeared in Super Mario World. Unlike the smaller Bullet Bills they are not shot from Bill Blasters, and just appear in some places, moving slowly horizontally. In later games, however, they are shot from large cannons. Like their smaller versions, they can be defeated by jumping on them.
As an assist
In SSB, Banzai Bills are gold and are found as missiles that are fired from Master Hand when he uses his Finger Bullet move. He fires one set of two Banzai Bills when above 100 HP and three sets if below. Each bullet does 5% damage.
As a stage hazard
In the stage Princess Peach's Castle, Banzai Bills appear from the sky and will start flying towards the castle. The Banzai Bill will then burrow into a random wall of the castle. It will then start to flash, indicating that it is about to explode. When a Banzai Bill explodes, any character in the blast radius will take heavy damage and extreme knockback. Banzai Bill's explosion involves numerous small hits before finally resulting in one final blow that causes a one-hit KO, though it is possible to DI out of the explosion before the final, fatal blow. Any character who makes contact with a Banzai Bill before it explodes will take light damage and knockback.
In early versions of Melee, the Banzai Bill trophy is named "Bullet Bill", and says "all Bullet Bills (in Melee) are extra large" instead of naming Banzai Bills at all; in reality, Bullet Bills are similar-looking but different enemies.
Like in Melee, 2D Banzai Bills appear in the background of Yoshi's Island.
Like in Melee and Brawl, 2D Banzai Bills appear in the background of Yoshi's Island.
Banzai Bills appear as enemies in Smash Run. Most of them chase the player, rotating to follow them, though some of them simply fly horizontally. After a while, homing Banzai Bills speed up and fly in a in single direction. They do 6% damage on contact, and can get stuck into the ground: if they are not destroyed in time they will explode, causing heavy damage and knockback to a nearby player.
Banzai Bills appear as part of the Mario-themed Vs. Enemy Team final battle.
In Smash Tour
A Banzai Bill can appear as a random event in Smash Tour. A warning appears at the beginning of the turn, and at the end a Banzai Bill hits the board and explodes, dropping numerous stat boosts and launching any Miis caught in the blast.
The Banzai Bill trophy appears in both versions of the game.
A giant bullet-like menace from the Mario series. In Smash Run, they want nothing more than to blow up on you. If you trick them into crashing, they'll get stuck and blow up soon after. Beware that lethal blast radius! Beat one before it blows up to get a banzai bonanza of stats. Tricky, but well worth the effort!
A giant bullety menace from the Mario series. In Smash Run, they want nothing more than to blow up on you. If you trick them into crashing, they'll get stuck and blow up soon after. Their blast radius is lethal, so keep well back! Beat one before it blows up to get a banzai bonanza of stat boosts. Not easy, but well worth it!
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.
As a stage element
Banzai Bills reappear in Super Smash Bros. Ultimate as stage hazards on the returning Princess Peach's Castle stage. While their behavior appears to be unchanged from Melee, their appearance has been changed to match more recent Mario games.
