Speed Burner

Speed Burner, also known as Rushing Burner (ラッシングバーナー) in Japan, is the weapon that X obtains from Flame Stag in Mega Man X2. When uncharged, this weapon shoots a pair of intertwined fireballs in the direction X is facing. When used underwater, only two non-flaming drones are shot and do little damage. A fully-charged Speed Burner causes X to air dash forward at high speed while surrounded by flames, damaging anything in his path. Morph Moth is particularly susceptible to this weapon in both of his forms. This weapon is also Zero's weakness, if the player fights him.
