Hammer Mario

Hammer Mario is a form of Mario or Luigi only seen in Super Mario Bros. 3 and its remakes, gained when he wears a Hammer Suit.

Super Mario Bros. 3 / Super Mario Advance 4: Super Mario Bros. 3
In this form, Mario and Luigi resemble a Hammer Bro and, like one, are able to throw an infinite supply of hammers in a short upward arc (which can be lengthened by pressing forward on the ). Hammers can defeat most enemies, even those that cannot be defeated with fireballs, such as the Angry Sun, Buzzy Beetles, Boos, Bullet Bills, Chain Chomps, Dry Bones, Firesnakes, Hot Foots, Podoboos, Para-Beetles, Stretches, and Thwomps; they can also defeat Boom Boom and Bowser. As such, this form can be considered a stronger version of the Fire form. As with fireballs, only two hammers can be thrown at a time, but hammers can fly through ceilings, walls, and floors. Mario and Luigi can also block enemies' fireballs in this form by crouching, but they cannot Slope Slide.

Despite the official artwork depicting Hammer Mario with his normal complexion and outfit colors underneath, his NES sprite depicts him with tan skin in levels, a white shirt, white shoes, and black overalls, while his 16-bit sprites depict him with a brown shirt and gray overalls.

Super Mario Advance 4 adds a new utility to this form: its hammers can break Gray Brick Blocks.

This form is not to be confused with Mario or Luigi wielding a hammer, with the difference being the infinite disposable supply of hammers and the black shell armor.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
In Super Mario Maker, Super Mario Maker for Nintendo 3DS and Super Mario Maker 2, knocking on a Warp Door in the Super Mario Bros. 3 theme may cause Weird Mario to appear in this form. In the latter game, Builder Mario's hammer can break hard blocks, similar to the Gray Brick Blocks in Super Mario Advance 4.

WarioWare: Twisted!
Hammer Mario appears in the second Super Mario Bros. 3 microgame from WarioWare: Twisted!, where it is one of the power-up forms that can be selected.

Trivia

 * In Super Mario Odyssey, despite the lack of power-ups (due to Mario gaining the Capture ability), Mario can capture an actual Hammer Bro in the game using Cappy and throw hammers to attack.
