O-Legion (オーレギオン Ōregion?) is Ban Yamano's fifth LBX introduced in the Danball Senki W series. It later became one of Mizel's LBXs.


Season 2


Mizel took control of O-Legion

O-Legion was developed to defeat the Vectors and Mizel, using the Eternal Cycler technology along with the body frame of AX-000, the strongest frame ever made. It first appeared in episode 51, given to Ban by Prof. Junichirou Yamano. It was used by Ban to fight against an army of Vector that were attacking Tiny Orbit. It used Stinger MissileJet Striker and Gao Cannon against the Vectors and easily beat them. Later, Mizel, who had hacked into network right as O-Legion was being completed, took control of O-Legion and used Gungnir to blow up a wall to come in and take O-Legion away.

Afterwards, O-Legion was used by Mizel all around the world and destroyed many facilities as a test run of its powers. There were several missiles that were fired on it, but none had so much as scratched it. Professor Yamano believed that O-Legion was the most powerful LBX ever, and the only thing that could oppose O-Legion, was another O-Legion, which was impossible to make due to not having the materials to make another one.

However, it was after Kirito stated that Professor Yamano could simply make another LBX in a customization that would enable them to counter O-Legion, without relying on another O-Legion. This enabled the production of another LBX that could counter O-Legion.

When Mizel used O-Legion to face Ban and Hiro, O-Legion damaged Ikaros Force heavily, easily defeating Hiro. However, before it could face Ban's Ikaros Zero, Achilles D9 arrived, and was synced with Ban's CCM. Mizel had O-Legion fight Achilles D9, believing that the new LBX couldn't stand a chance against O-Legion. However, after Stinger Missile was countered by Sword Bit, Achilles D9 struck a blow on O-Legion and damaged it, forcing Mizel to retreat.

Afterwards, to strengthen O-Legion before utilizing his final plans, Mizel left his android body to merge with O-Legion, transforming it and becoming Mizel O-Legion.
