Ground Fire (グランドファイア Gurando Faia?) is Mega Man X's weapon from defeating Mattrex in Mega Man X5. In normal fire, X shoots a swirling fireball on the ground that shoots three embers in random directions. The embers cannot go through walls and can only be shot out in the direction in which it has not placed itself on (i.e., if the Ground Fire sticks to a ceiling and a wall, the embers will not be fired to in the direction of the ceiling and the wall). Up to two Ground Fires can be on the screen at a time. When charged up, X shoots out two fiery blasts on both sides of him. Unlike previous fire-based weapons such as Fire Wave and Speed Burner, Ground Fire can even be used underwater, such as Duff McWhalen's stage.
