Core is a Darkus Stealth Bakugan. He belongs to Baku-Cool in Bakugan: Wind Tamer. Core's Mechtogan is Vaxior, his Mechtogan Titan is Dranzer and his Battle Suit is a Darkus Defendtrix. Core's MechFrame is ScytheD. His full name is Core Reaper Meteora. Core is also the Bakugan tritagonist of the series.
Core can change attributes to Pyrus and Aquos. His defense and attack mode are grounded and solid. He punches the ground to destroy a Gate Card. The blue lens on Core's chest lights up the lines on his body, which runs through his arms to the fists powering them up for massive energy punches that hit the ground and makes rocks float up in the air, then punches them again and uses them as projectiles to smash the enemy. A dimensional hole in his palms absorbs all energy from an attack. Core uses his music to distract an opponent.
Core is extremely laid back and can be considered a "party Bakugan", with him being well-known for his party boy attitude. Core loves to cause massive damage to his opponent during battle. When he is not battling or partying, he is one of the most loyal Bakugan you could ask for.
In The Darkus Tamer, Core is sent from a party club, so he can help Hurricanos. When meeting BC, Core bonds with him rather fast. BC tells his friends that he traded his Lumino Dragonoid for Core during the episode. Later, Core loses a battle against Dark.
