BB Senshi #284 Tekki Musha Saiko

BB Warrior No.284 Iron Machine Warrior Saiko (Saiko) (Saiko / Musha Buffalo: Musha Bison / Musha Fortress: Psycho Gundam (MA form) / Musha Cruiser: Gun Cruiser Mk-I (MA form))

Saiko is an Iron Machine Warrior created by Davidsota. He was slashed and destroyed by Taketan, who had disguised himself as Maaku. Based on the context of this work, including before the remake, it is believed that Davidsota discovered the main system of the "excavated weapon" and fused it with a body he made himself, resulting in its current form. Taketan, mentioned later, then combined it with another "excavated weapon" (body) to restore it to its original form.

Within the series, Saiko was modified for its original purpose as a control device called "Sotai Zero" (for more details, see the section on Rekka Team's Saizo). Later, Saiko was separated from the Iron Machine Manual and resurrected by being installed in the original body, the "excavated weapon." Saiko can transform into various forms, including Musha Bison, Musha Fortress, Musha Cruiser, Ground Assault Dragon Cannon, and Airborne Bomber. Each part can also be used as equipment for the Seven Luminaries of Light.

In "Zero," because the Iron Machine Manual was incomplete, Saiko had self-awareness but could not move in combat without Davidsota's command.

Weapons include a rotary cannon, Saiko Gun, Destructive Mace, Eye Bullets, and the Crushing Sword Muramasa.
