|This article is about a/an weapon in B-Fighter Kabuto.|
Geist Axe (ガイストアックス Gaisuto Akkusu?): The Geist Axe is a green axe with a green crystal ball similar to the Astral Saber's in its hilt. Within it is a mechanical stag beetle that becomes the giant Kuwaga Titan. Initially, Descorpion was the wielder of the Geist Axe and the commander of Kuwaga Titan.
After Kabuterios and Kuwaga Titan defeat each other, its hilt turned to stone, returning to normal in episode 41 with Mother Melzard as the new wielder. She lost the Axe in the next episode. Later in the finale, with the New B-Fighters' Insect Commanders merging into it, B-Fighter Kuwager got possession of the weapon and used the power of Kuwaga Titan for good. It disappears after the final battle.
