Fire Breath

Fire Breath (クッパブレス, Koopa Breath) is 's standard special move in Super Smash Flash 2. The attack consists of Bowser releasing a slow moving, hard hitting fireball from his mouth, which has high startup and ending lag.

Origin
Fire breathing has been Bowser's signature attack since his debut in Super Mario Bros.. In said game, Bowser (and also his minions disguised as him) releases fireballs from his mouth at different heights and intervals in an attempt to stop Mario or Luigi. In subsequent games in the series, Bowser is also able to release a constant stream of fire and opposed to simply fireballs.

Trivia

 * The move was initially meant to be similar to how it works in the Super Smash Bros. series where Bowser would release instead a stream of fire and, as the time passed, the stream would reduce in size, damage and knockback. This was changed for balancing purposes.
