'''''B-Fighter Kabuto''''' is Toei's 15th entry in its ''Franchise/MetalHeroes'' series, and the second of its ''B-Fighter'' series. Its footage was used to create ''[[Series/{{Beetleborgs}} Beetleborgs Metallix]]''.

Ten years after the Jamahl Empire fell, a new threat, the Melzard tribe, emerges. At the revamped Earth Academia called Cosmo Academia, Takuya Kai and Guru work on a new generation of Insect-Powered PoweredArmor suits. When the Melzard launches their first attack, two of the suits are immediately entrusted to Kengo Tachibana and Ran Ayukawa. The third is soon entrusted to OrdinaryHighSchoolStudent Kouhei Toba. With the new team in place, the Melzard's schemes for Earth have reached a dead end.

* Kouhei Toba/'''B-Fighter Kabuto''': TheHero; an OrdinaryHighSchoolStudent who becomes involved in the fight against evil.
* Kengo Tachibana/'''B-Fighter Kuwaga''': [[TheBigGuy Big]] [[TheLancer Lancer]]; a student inititally bitter with Kouhei for taking the mantle of B-Fighter Kabuto instead of him. However, he does warm up to our hero.
