Gurabura is the final boss of the Mars stage route of Aero Fighters 3/Sonic Wings 3 and the minor boss of the Mexico stage of Sonic Wings Special. It is a large UFO used by the aliens who wanted to invade Earth and destroy mankind, now remaining stationed at Mars. This boss is extremely fast, which makes the battle very hard, plus the fact that the battle is time like all other final bosses in the series. If the player fails to defeat him, a bad ending will play where Gurabura tears the planet Earth apart.
