Mag Fly (マグフライ) is an enemy native to Magnet Man's stage, and in Mega Man 3 only appear in the first section of the stage. They pull Mega Man up and carry him with the large magnet they possess. This can be dangerous if the player is trying to cross a pit. In Mega Man 3, Mag Flies are immune to Search Snakes, Spark Shocks (and Magnet Missiles, only though the use of an external cheating device), but can be destroyed in one hit from any other weapon.

In Super Adventure Rockman. Mag Flies appear in Episode 3, where they throw spiked metal balls.
