Flame Chomp

Flame Chomps, originally Fire Chomps, are enemies that first appear in Super Mario Bros. 3. They resemble Chain Chomps, but differ in several ways. First, they are not restricted by chains, and instead float along with a trail of four fireballs. At any time, they may shoot fireballs from their "tail" at Mario or Luigi. When it runs out of fireballs, the Flame Chomp will explode, damaging the Mario brother if they are within the blast radius. Also, unlike Chain Chomps, they are vulnerable to stomps and fireballs. They live mainly in the skies.

Super Mario Bros. 3
In Super Mario Bros. 3, Fire Chomps only appear in Sky Land and Ice Land. They float along as Mario and Luigi navigate the stage, harrying Mario's progress on the small platform with their fireballs. They are especially prevalent in World 5-9, where the player has a limited amount of platforms they can jump onto, in addition to an automatically scrolling screen. After using up their fireballs, Fire Chomps will continue to follow Mario or Luigi shortly before exploding like Bob-ombs. They can be defeated with stomps, fireballs, hammers, Starmen, and tail whips. In this game, their faces only appear when they shoot their fireballs.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64 and Super Mario 64 DS, while no normal Fire Chomps appear in the game, a derivative known as Keronpa Ball is introduced. They are motionless and shoot a homing fireball when the player approaches. Unlike usual Fire Chomps, they do not self-destruct or run out of fire. These objects originally lacked faces or an explicit connection to Fire Chomps, which were given to them starting with the remake.

New Super Mario Bros.
Flame Chomps return in New Super Mario Bros. as uncommon enemies, appearing only in World 7-1. They retain their previous characteristics and weaknesses from Super Mario Bros 3., with the exception that they now depict 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, it begins 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, the second level of the Mystery Adventures Pack, and the second level of the Impossible Pack, with the same characteristics and weaknesses as in New Super Mario Bros. Wii.

New Super Mario Bros. U
In New Super Mario Bros. U, there is only one Flame Chomp in the entire game, located in a hidden room in Rising Tides of Lava. It can be bounced off of to obtain the stage's third Star Coin, and acts the same as its previous appearances.

New Super Luigi U
Flame Chomps also appear in New Super Luigi U. 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.

The Adventures of Super Mario Bros. 3
Fire Chomps make several appearances in The Adventures of Super Mario Bros. 3, such as in the episode "The Beauty of Kootie", where several Fire Chomps act as crew members on Bowser's Doomship.

In the show, Fire Chomps do not have a fireball tail, and have flexible borders around their eyes (which this time are red) and mouth. Fire Chomps also appeared during the episode "Never Koop a Koopa". They tried to attack Mario inside Castle Koopa, but Toad and Princess Toadstool opened the window and let them fall into the water.

Nintendo Adventure Books
A Fire Chomp appears in Koopa Capers, prowling a cave in the Magma Pits. While Luigi is fleeing from the Hot Feet that also live in the cave, he can choose to either rush blindly ahead, or take his time; if he chooses the latter, he will just narrowly avoid the Fire Chomp, but if he picks the former, he will run into and be scorched by the fireballs of the Fire Chomp, causing a Game Over.

Super Mario Bros. & Friends: When I Grow Up
A single Fire Chomp cameos in Super Mario Bros. & Friends: When I Grow Up on the Homemaker page.

Super Smash Bros. for Nintendo 3DS
Flame Chomps appear in Super Smash Bros. for Nintendo 3DS as enemies in the exclusive Smash Run mode. Like in previous games, they breathe fireballs at the player and explode shortly after losing all of their fireballs. The fire trail can also damage the player if they run into it.

Puzzle & Dragons: Super Mario Bros. Edition
Flame Chomps are enemies who can become allies to the player in Puzzle & Dragons: Super Mario Bros. Edition. A Flame Chomp's attribute is Fire, meaning that it is powerless against Water, yet strong to Wood. Flame Chomps have relatively high HP and they are very efficient in regenerating their team's health points. Instead, their attack point rating is a little poor. The main skill of any Flame Chomp in the game is called Flame Dance, which increases the attack rating of every Fire-type team mate by 1.3 for five turns. Flame Chomps also have a secondary skill, the Skill Boost; when the player enters a course, this skill helps by reducing the number of turns till the main skill can be used.

Other appearances
In the Super Mario Mash-Up Pack in Minecraft, Blazes are replaced by Flame Chomps.
