Fryguy

Fryguy (also spelled Fry Guy ) is the boss of World 4 in Super Mario Bros. 2. He is a living ball of fire created by Wart in Subcon. Fryguy first appeared in Yume Kōjō: Doki Doki Panic.

Super Mario Bros. 2
During the events of Super Mario Bros. 2, Fryguy is stationed in a tall fortress at the end of World 4, since their conquest is almost complete. Despite Fryguy's being a living flame, World 4 is a land of snow, ice, and arctic oceans of Subcon. When confronted by Mario and his friends, Fryguy becomes enraged and spits fireballs to attack the heroes. Since Fryguy is made of fire, the heroes take damage if they happen to touch the living embodiment of flame. To defeat Fryguy, Mushroom Blocks must be thrown at the fire monster. After three hits, Fryguy splits into four Small Fry Guys, which must also be extinguished. He was voiced by Charles Martinet in the Advance version, owing to that version including voice acting for the various boss characters.

BS Super Mario USA
Fryguy appears once again as a boss in the pseudo-sequel, BS Super Mario USA. He helps Wart and the other 8 bits attack Subcon once more, but is eventually defeated by Mario and the other heroes once again. Like the predecessor, he is found in the snowy lands of Subcon and he is fought in a very similar way to that of Super Mario Bros. 2.

The Super Mario Bros. Super Show!
Fryguy was a character in The Super Mario Bros. Super Show!. Like many enemies on the show, the fire monster worked for King Koopa, as opposed to Wart (as in the video games). Fryguy did not appear as much as other Super Mario Bros. 2 enemies on the show.

Nintendo Comics System
Fryguy also appeared in the Nintendo Comics System's Mario comics. In the comics, there was not one Fryguy, but multiple Fryguys. Also, these Fryguys were not magically created living fireballs; these Fryguys were created when a Toad becomes engulfed in fire or lava. In one comic story, Duh Stoopid Bomb!, a sole Snifit becomes a super-genius after being exposed to one of Bowser's inventions. This Snifit than performs a coup and takes over Bowser's Castle. After the coup, Bowser is expelled to "Fryguy Kindergarten".

Nintendo Adventure Books
Fryguy and some of his GLOM-spawned clones try to attack Mario as he is exploring the Mushroom Kingdom in Double Trouble, but he avoids them.

Super Mario-Kun
Mario, Luigi, and Yoshi encounter Fryguy in volume 8 of Super Mario-Kun. The Fryguy and his minions attempt to cook them in a soup, but Toad and Birdo arrive by breaking through the sky, riding on a whale. The whale then flattens Fryguy and his minions.

Miscellaneous
In the Super Mario Bros. film, the flamethrowers used by Koopa and his minions are referred to as "Fryguy Flamethrowers."

In Super Mario Bros. & Friends: When I Grow Up, the backstory of the Firefighter career page reveals that Fryguy has started a fire.

A Sammer Guy in Super Paper Mario is called Guy Who Fry.
