Plot
Five years after the destruction of Jamahl, Earth has returned to peace again. The Earth Academia has become the , a scientific research and military organization, where Takuya Kai works with Sage Guru on a new generation of Insect Armor in the event of another threat to the Earth.

This threat is realized when a Cosmo Academia exploration submarine comes across a fissure in the ocean floor, out of which rises a huge flying fortress of the ancient tribe Melzard. This clan has been resting for millennia and seeks to destroy mankind. Matriarch Mother Melzard sends her oldest sons Raija and Dezzle to lead the attack with Raija's Elebamamoth. By then, Guru has infused the Neo Insect Armor with Insect Power, creating the three Command Voicers to link three humans with the armor. Kengo Tachibana and Ran Ayukawa, who have been selected to wear the new armor, ready themselves and become B-Fighter Kuwagar and B-Fighter Tentou. But the person to become B-Fighter Kabuto had not been chosen when the remaining Command Voicer flies out the window. Ran and Kengo follow it to meet Kouhei Toba, a star athlete at his school who is losing badly to Elebammoth who froze the boy's sister as the last Command Voicer flies into his hand. Kengo and Ran are shocked that this high school student is to be B-Fighter Kabuto, but they go to him and teach him how to transform. He changes into Kabuto and the three of them attack Elebammoth and several henchmen, with Kabuto killing Elebammoth.

Refusing to accept defeat, Mother Melzard continues her attacks, with Raija and Dezzle working against each other in their attacks on the B-Fighters.

After the battle in which Kabuterios and Kuwaga Titan defeat each other, Mother Melzard fell asleep, gaining an eye on her left breast upon waking up and taking control of Kuwaga Titan. After a battle on the moon with Kabuterios, the Geist Axe was lost. Mother Melzard then proceeded to use a rain to implant bombs in all humans in a scheme to wipe out the entire population. When the B-Fighters entered her fortress, she fought them personally before activating the bombs, leaving only Kabuto unaffected. Severing her connection to the Melzardos, the New B-Fighters destroyed the detonator as the Melzardos crashes.

Dord placed Dezzle's head on a tank. Dezzle was later revived by Mother Melzard in a new, mysterious form. His new form, giving him new power from the darkness of the deep sea, had a small torso, a black cape, and a white mask which hid his face. Dezzle later found the B-Fighters' base of operations, assuming Professor Osanai's form to activate the BF Base's self-destruct along with a virus to spread to the other branches. He overpowered Kuwagar and Tentou as Kabuto arrived. They took the fight outside while Professor Osanai deleted the virus. He almost killed Kabuto until he was hit by the Input Rifle.

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.
