Insane Cannon Lance

Insane Cannon Lance is Insane Black★Rock Shooter's signature weapon. It is a vastly modified version of her normal ★rock Cannon.

Appearance
The Cannon Lance is a longer, spiked version of the ★rock Cannon. It has a large blade at its end instead of a recognizable barrel for a gun, hence the name "Insane Cannon Lance". Instead of a single barrel the Lance has a battery of vulcan turrets scattered around its blade, as well as a single backward-firing turret on the underside. The turrets retreat into the casing when not in use. Cannon Lance has a trigger and handle on one end, with a chain attached to it which allows Insane Black★Rock Shooter to control it from a long distance.

Abilities
The Cannon Lance, unlike the ★rock Cannon, has only one fixed form and cannot switch between charged-fire and rapid-fire incarnations, firing only rapid-fire blasts from its multiple turrets. The long spike at the end enables it to be used as a throwing and stabbing weapon; the turrets on the casing can be controlled by Insane Black★Rock Shooter even when it is in mid-air, allowing it to shower the battlefield with blasts from almost any angle. The Cannon Lance also has a rear-firing turret on the underside which can hit enemies if the front end of the weapon is pointed away from the enemy. Despite having a lower rate of fire, it was powerful enough to shoot the enemy's (namely Black Gold Saw's) arm off.

History
The Insane Cannon Lance was first seen in action in Episode 6 of the anime, used by Insane Black Rock Shooter against Black Gold Saw. Despite BGS drawing first blood in their duel, I.BRS quickly gained the upper hand with her weapon's rapid-fire ability and strong melee attack. She also used the "remote control" feature, controlling the weapon in mid-air with chains, to her advantage.

The Lance Cannon was later used in the same episode to battle Strength. Despite the Lance's fierce abilities, it was overwhelmed by the immense brute force of Strength's Ogre Arms, and Insane Black Rock Shooter appears to have lost the fight.

In the next episode, it is used against Strength after Insane Black★Rock Shooter manages to recover and regain the upper hand. It is powerful enough to defeat Strength's machine and gatling guns. However, when Strength turns out to be the real Yuu Koutari, she takes the Cannon Lance from Insane Black★Rock Shooter and activates all its vulcans at once to hurt yourself. After another shoot-out between the two, Strength covers the world in fire. Insane Black★Rock Shooter uses the Cannon Lance to propel herself over the flames, but Yuu manages to beat her by deploying four Ogre Arms at once and throws the Cannon Lance away.

In Episode 8, Insane Black★Rock Shooter uses the chain attached to the Cannon Lance to pull it back and attempts to finish Yuu with it. However, Mato stops her and the two are transported to Black★Rock Shooter's world, with Mato in the normal Black★Rock Shooter's body. Insane Black★Rock Shooter initially abandons the Cannon Lance and uses her fists to pummel Mato, but when Mato summons the ★rock Cannon in gatling gun form, Insane Black★Rock Shooter uses the Cannon Lance to fight her. During the ensuing shoot-out, the ★rock Cannon and the Cannon Lance's vulcans are evenly matched due to the ★rock Cannon having heavy firepower in gatling gun mode. Eventualy, Mato summons a giant ★rock Cannon with help from the "other selves" and both Insane Black★Rock Shooter and her Insane Cannon Lance are annihilated.
