Darkness Generals B-Crushers (闇の四鎧将ビークラッシャー, Yami no Shigaishō Bī Kurasshā) are the Melzard's primary fighters against the B-Fighters. Raija and Dezzle gathered 4 of the 8 Insect Medals (first obtaining the Centipede Insect Medal, then the Bee, Mantis and the Scorpion Insect Medal afterwards) for Mother Melzard using energy gathered by Dezzle. She had four of her larval offspring merge into suits of armor powered by the medals. In their debut, the B-Crushers lured the B-Fighters into the open and sprang a trap. The B-Crushers overpower them until Mac Windy comes to aid as B-Fighter Yanma. Descorpion ordered a fall back as they proved their superiority. But in the second match, Kabuto defeated them. After B-Fighter Kabuto activated Kabuterios, the B-Crushers were injured and had to be cocooned until their wounds had healed. Afterwards, they gained possession of the Geist Axe. They also came to be at odds with Raija, Dezzle and their crew.
