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. In this form, he resembles a Hammer Bro and, like one, is able to throw an infinite supply of hammers in a short upward arc (which can be lengthened by pressing forward on the ), which 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, Fire Snakes, Hot Feet, Lava Bubbles, Para-Beetles, Stretches, and Thwomps; they can also defeat Boom Boom and Bowser. As such, Hammer Mario can be considered a stronger version of Fire Mario. As with fireballs, two hammers can be thrown at a time, but hammers can fly through ceilings, walls, and floors. Mario can also block enemies' fireballs by crouching, but he cannot Slope Slide. Despite his official artwork depicting Hammer Mario with his normal colors underneath, his NES sprite depicts him with a white shirt and black overalls, while his SNES sprite depicts him with a yellow shirt and gray overalls.

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

In Super Mario Maker and Super Mario Maker for Nintendo 3DS, knocking on a Warp Door in the Super Mario Bros. 3 theme may cause Weird Mario to appear in this form.

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, as a reference to this form.

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.
