★Rock Cannon

The ★rock Cannon is the name of the very large gun used by Black★Rock Shooter. There's also a similar weapon used by White Rock Shooter in her other form (as seen in her intro.).

Appearance
It is obvious that ★rock Cannon is a very large gun when Black★Rock Shooter wields it. Also, it can be guessed that the trigger and handle to shoot is inside the gun because of the way Black★Rock Shooter attacks with it. Unlike Black★Rock Shooter's wielding style, White Rock Shooter seems to be holding it differently, pretty much how she holds her scythe in battle. Also, it's length and size are undefined, because sometimes it's shown larger and longer and also sometimes, it's shown shorter.

Background
Not much is known about ★rock Cannon, only that Black★Rock Shooter obtained it somehow after the fight between her and Black★Gold Saw. She is seen walking around the Otherworld with it in her hand and fighting Dead Master with a giant blade that she was able to transform ★rock Cannon into. In the Game, she obtains it after being awakened in her stasis tube along with the Black Blade. The weapons might be an invention of Prof. Gibson.

Abilities
★rock Cannon's abilities are seen in the Black Rock Shooter Pilot and OVA. When Black★Rock Shooter loses her katana in a fight between her and Black★Gold Saw, she is seen walking around with her new weapon, ★rock Cannon.

★rock Cannon's attacks several different ways so far:
 * Capable to shoot 20 rocks per second
 * Can be transformed into a giant blade
 * Strong enough to be used as a shield against attacks
 * Can not only shoot rocks/bullets, but also blast orbs (similar to a cannon-ball).
 * Can charge certain amounts of energy to unleash a devastating blast (in the Game).
 * Can transform into a multitude of weapons.
 * WRS can transform her Rock Cannon along with her wings to form the cannon that fires her Grateful Sunray.
 * It can be turned into a Gatling gun
