Gan Gun Hand

The Gupa Handgun Gan Gun Hand (グーパー拳銃ガンガンハンド) is a club-like multiform weapon with a hand-like feature around the muzzle wielded by Kamen Rider Specter. It first appears in episode 5.

The Gan Gun Hand was briefly stolen by Kamen Rider Necrom, using it against Specter and Ghost.

Modes
Similar to Kamen Rider Ghost's Gan Gun Saber, the Gan Gun Hand has two basic modes along with an additional mode it can access by combining with a specific Ghost Gadget. Each mode is compatible with a different Damashii form that Specter assumes.

Standard=
 * Rod Mode (ロッドモード): The default mode, primarily used in Specter Damashii. When used in Edison Damashii, the Gan Gun Hand can elongate to grab the opponent and sends painful electric shocks.
 * Gun Mode (銃モード): To utilize this mode, Specter must slide the weapon's orange tab forward to close its "fingers" into a clenching fist-like shape which reveals a gun barrel. In terms of Specter's forms, Nobunaga Damashii has the most compatibility with this mode.

Finishers
The Gan Gun Hand's many different named Omega Drive finishing attacks are activated when Specter initiates an Eye Contact (アイコンタクト) by scanning the Energy Eye Crest (エナジーアイクレスト) on its hilt with the Ghost Eyecon currently placed in his Ghost Driver. Additionally, after scanning the Energy Eye Crest on the Gan Gun Hand's hilt with the Ghost Eyecon currently placed within his Ghost Driver, Specter pulls and pushes the lever of the Ghost Driver to increase the Gan Gun Hand's finisher. Rod Mode=
 * Omega Smash (オメガスマッシュ): In Rod Mode, Specter creates a large energy projection of the Crash Fingers (クラッシュフィンガーズ) and strikes the targets with it. First seen in Kamen Rider Ghost: Game de Kaigan!!.
 * Omega Fang (オメガファング): In Sickle Mode, Specter creates a large projection of the behind the enemy before striking them with an energized slash from his weapon that knocks said enemy into the projection. Afterwards, he pulls the trigger to cause the Eye of Providence to disintegrate and ultimately destroy the enemy trapped within. Against giant or multiple enemies, Omega Fang can also be utilized simply as an energized slash.
 * In Episode 11, Specter uses this finisher in his normal form to take out Gundari.
 * Omega Spark (オメガスパーク): In Gun Mode, Specter creates two temporary rows of copies of his weapon to target and fire a barrage of shots at the enemy alongside the original, with the copies vanishing after they've all fired off a single shot.
 * When Specter uses this finisher in his Necrom Specter form, he charges green energy from the Gan Gun Hand and fires at the enemy. This finisher was stopped by Necrom when Kanon shielded Ghost to protect him.
