―Finisher announcement[src]

The Birth Buster (バースバスター Bāsu Basutā) is Kamen Rider Birth's personal firearm weapon, created by Doctor Maki as part of the Kougami Foundation's Medal System. It first appears in Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core, and then made its TV debut in episode 16.

In Normal Mode (ノーマルモード Nōmaru Mōdo), it is a gun that uses Cell Medals as ammunitions, firing medal-shaped energy bullets. Birth can reload the Birth Buster with Cell Medals by using the Cell Bullet Pod (セルバレットポッド Seru Baretto Poddo), which can also be mounted on the forend to act as an auxiliary grip. In Cell Burst Mode (セルバーストモード Seru Bāsuto Mōdo), the Cell Bullet Pod is attached onto the Birth Buster's muzzle, making it capable of releasing an explosive ball of energy so long as it has at least one Cell Medal.

As shown in episode 18, it can be used untransformed but the recoil of the gun is very powerful, as evidenced by Shintaro Goto was thrown flying backwards after firing just one shot, when he fired the gun for the first time. Date later allows him to use and keep it, as so to prepare Goto in becoming Birth once Date achieves his goal of acquiring one hundred million yen. After giving Goto the original Birth Buster, Date obtains a replacement from Maki.[1]

When Satonaka becomes Goto's assistant, she also wields a Birth Buster.


The Birth Buster is also among the various Rider Weapons used by Ganbarider in Kamen Rider Battle: Ganbarizing.

Behind the scenes


The voice of the Birth Buster, as well as the Birth Driver, is provided by Jōji Nakata (中田 譲治 Nakata Jōji), who is also the narrator of OOO.
