Sakomoto was the original Blue Fighter of the Armored Mobile Task Force. When an evil demon overtook the mind of his partner Yasuda, Sakomoto found that his powers weren't enough to fight off the demon and his brainwashed partner. Initially losing the battle, Sakomoto was able to evolve into a new stronger form, Blue Fighter Alpha. With his new powers he was able to free Yasuda from the mind control and transferred his original powers into his young partner. With Yasuda as "Blue Fighter V2", Sakomoto was able to defeat the demon. Now Kubotchi has two Blue Fighters to defend it.
