Flame Chomp also known as Fire Chomp, or Keronpa as they are known in Japan, are chainless Chain Chomps similar to Amps.They first appeared in Super Mario Bros. 3 and have appeared in every game of the New Super Mario Bros. series.
In Super Mario Bros. 3, these enemies have four fireballs each, and when they've fired every one, they will explode, damaging everyone in the blast radius. In this game, Flame Chomps have greyish-white bodies and only show their faces in "attack mode", with their "dormant mode" sprite showing them as faceless balls. Mario can defeat the Flame Chomp by way of using a Starman or the Raccoon Suit's tail whip up against their body.
Super Mario 64 DS
In Super Mario 64 DS, Flame Chomps replace Kuromame from Super Mario 64, and serve the same purpose. They remain motionless and have the same effect as them, shooting a flame at the player when they approach; they can be eaten by Yoshi, allowing him to breathe fire. Due to the nature of their roles, it is their first, and so far, the only appearance where they do not self-destruct or run out of fire.
Flame Chomps return in New Super Mario Bros. as uncommon enemies, since they only appeared in World 7-1. They retain their previous characteristics and weaknesses from Super Mario Bros 3., with the exception that they now show their faces at all times.
New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Flame Chomps are a bit more common, appearing in World 2-6, World 8-3, and World 9-6. Flame Chomps have a minor addition to their attack pattern; once out of fireballs, they begin chasing Mario much faster before exploding. They can be defeated with a stomp or fireballs, and can also be frozen with Ice Balls.
New Super Mario Bros. 2
In New Super Mario Bros. 2, Flame Chomps exclusively appear in World 6-B, with the same characteristics and weaknesses as in New Super Mario Bros. Wii.
New Super Mario Bros. U
In New Super Mario Bros. U, Flame Chomps make their only appearance in a hidden room in Peach's Castle-3: Rising Tides of Lava. The enemy must be bounced off to obtain the stage's third Star Coin, and acts the same as their previous appearances.
New Super Luigi U
Flame Chomps also appear in New Super Luigi U, the first game where they are referred to by their current name. They also have a new attack, which involves shooting all the fireballs in their "tail" at once, creating a larger fireball. Many of them appear in Flame Chomp Ferris Wheel which is also their only appearance in the game.
