The Parabola Gun (パラボラ砲) is an old gun that is part of Nino Island's defense system. During Glyde's attack to the island, Roll Caskett repaired the Parabola Gun while Mega Man Volnutt protected her from the attack of Glyde's King Glydon airship. When Roll finished, she used the Parabola Gun in the airship, making Glyde and the Birdbots confuse to the point they exploded their own airship.
