Battle Crusher is a Bakugan Battle Gear. It is a mega-cannon blaster with an auto target lock feature that will fire as many shots as needed. It fires flashes of energy beams that can tear into an opponent. It operates a directional defense system to protect itself. Battle Crusher has the ability to upgrade itself on command.
In The Visitor it was used by Fabia to battle Drago but they were both defeated.
It reappears to battle against Plitheon but lost due to the bug in the field. Battle Crusher was to battle Phosphos but failed, though they managed to defeat Lythirus and Plitheon later on. It was used to battle Lumagrowl but failed.
Battle Crusher Duke (Combat Pressure Mode/Battle Crusher Mode/Battle Crusher Doom): Adds 500 Gs to Battle Crusher and halves the effects of all abilities the opponent uses afterwards. (Happens on all rounds) (Level 1 class ability)
Battle Crusher Demise (Battle Crusher Extreme/Battle Crasher De-Light): Subtracts 600 Gs from each opponent. (Level 2 class ability)

It was released along with Lansor, Terrorcrest, and Barias Gear. An 80 G Copper version comes with the Target exclusive Bakugan Combat Set with Haos Aranaut. Another Copper one comes in Brawler Game Packs with 100 Gs. A normally-packaged Copper version has 100 Gs. A Silver variation has 80 Gs. Battle Crusher's cannon can be angled forward.
Haos Effect: You get +50 G-Power for each Gate Card in your enemy's used pile if your enemy has more Gate Cards in his used pile than you.
Darkus Effect: If your opponent has a Gear or Trap at the battle you get +50 G-Power.
When closed it appears very similar to a GN Drive from Mobile Suit Gundam 00.
Its original name was Battle Crasher in the anime.
Barias Gear often comes in game packs with Battle Crusher probably because they're both Haos Battle Gear.
In a deleted scene from Dream Escape it was revealed that a point-blank range attack from Battle Crusher can easily kill a Bakugan, and Rubanoid only survived thanks to his "Solid Body", however, he was still badly injured and had to be treated in a special tank.
