Cobra Keitai

The Cobra Keitai (コブラケータイ) is the sole Ghost Gadget that aids Specter in fighting the Gamma and Ghost. This particular Ghost Gadget can switch between Gadget Mode and Animal Mode. When Specter assumes Tutankhamun Damashii, the Cobra Keitai combines with his Gan Gun Hand to form the latter's Sickle Mode (鎌モード) by transforming partially into its Keitai Mode, with half of its Master Mobiler (マスターモバイラー) opening up in half to form the Scythe Edge Tail (サイスエッジテイル), with the back of the Serpent Display (サーペントディスプレイ) connecting to the Gan Gun Hand.
 * The DX Cobra Keitai toy is able to combine with the Gan Gun Saber to form an unofficial Scythe Mode, complete with a different Omega Drive announcement.

The Cobra Keitai was evidently created as a compliment for Tutankhamun Damashii to counter the Gammaizer Time.
