Gunner A

The Gunner A (ガンナーA) is a robotic tank that serves as Kamen Rider Accel's support droid. Its AI allows it to operate on its own from Accel. The technology is similar to Kamen Rider Double's HardBoilder and the front unit can also combine with the Gunner A to become the HardGunner.

AccelGunner
Kamen Rider Accel Bike Form can combine with the Gunner A to become the AccelGunner (アクセルガンナー). The Accel Memory links with the Gaia Cannon (ガイアキャノン) to release energy similar to a Maximum Drive called the Gunner Full Break (ガンナーフルブレイク). It is also armed with the Gattling Wheel (ガトリングホイール), Bike Form's back wheel turned into a machine gun.
