Morgun

Morgun (モーガン) is an enemy in Mega Man X2 that looks like a flying squirrel with its tail on fire. It shoots fireballs and if it lands near a gas pipe, will set the gas on fire for a while. It appears only in Flame Stag's stage.

Trivia

 * Hidden in the data for Mega Man 9 are graphics for a similar enemy that was cut from the game.  Much like Morgun, it was also a squirrel that glided with a flaming tail, although orange in color due to emulating the color limitations of the NES and Famicom.
