Musha Psycho Gundam

Musha Psycho Gundam (武者斎胡頑駄無) is a member of the Musha Shichinin Shuu characterized by the largest physique and greatest physical strength within the Gundam Army. Based on the MRX-009 Psycho Gundam, the design features a heavy armored silhouette with a head unit that uniquely incorporates the English text PSYCO on the forehead. Its primary equipment includes a large metal club (Kanabo) that can be mounted on its backpack, a large cannon, and a hidden katana concealed within the handle of the club.

The mecha is accompanied by a support animal named Bison, which can combine with its armor and weaponry to form Musha Bison. In its initial appearance, it was controlled by a Brainwashing Mask (洗脳マスク) that gave it a more menacing appearance with a red visor. It can further power up by equipping the Mountain Armor (山の鎧) to become Kyozan no Saiko (巨山の斎胡), significantly increasing its defensive bulk and adding elaborate gold-plated horn ornamentation to its helmet.
