Kabuto Kunai Gun

The Kabuto Kunai Gun (カブトクナイガン Kabuto Kunai Gan) is Kabuto's personal sidearm that has three modes to use the weapon in various forms.
 * Gun Mode (ガンモード Gan Mōdo), the default mode, fires high-intensity ion beam blasts and is equipped with tri-laser targeting called DAT Sight (ダットサイト Datto Saito). Its finishing attack is an ionic energy blast called the Avalanche Shoot (アバランチシュート Abaranchi Shūto).
 * Axe Mode (アックスモード Akkusu Mōdo) becomes active when the gun barrel is held, and is wielded by using the bladed butt of the weapon like a tomahawk. Its finishing attack is the Avalanche Break (アバランチブレイク Abaranchi Bureiku).
 * Kunai Mode (クナイモード Kunai Mōdo) activates when the gun barrel is detached, unsheathing a short-dagger weapon good for its swift and easy handling; this is favored most when Kabuto switches to Rider Form. This mode's finishing attack is the Avalanche Slash (アパランチスラッシュAbaranchi Surasshu).
