The Getter Navalon Cannon is a defense weapon installed on the Saotome Institute.
Appearance and Functions Edit
The Getter Navalon Cannon is a large two-pronged cannon attached to an elevating rod. The cannon's firepower is enough to take out a Mechasaurus in one blast if the attack connects. It also uses special gun shells created by Bunji Daiko for dealing with multiple enemies.
The Navalon Cannon was used during the second half of the anime to defend the Institute from threats should the Getter Robo not be enough. Strangely enough, the weapon never made an appearance in the finale or subsequent series.
