Alias "Mark Two". Third of the seven. His father, Hayabusa Gundam, is one of the Four Beast Kings that fought alongside Shodai Shogundam. Previously a hunter, he saved Shodai Shogundam in a forest, thus earning the title "Musha" and a place in the Seven Musha. During his training, he gained the eagle guardian beast and learnt the ways of land and air battle. Taught Noomaru nitouryu (2 sword style).
It appears in a battle against Kinkaku and Ginkaku, the monks who protect the "Golden Scroll of Model Secrets". Its name is "Mk-II", but this does not mean "Mk-II Gundam that became a warrior", but "Mk-II of Musha Gundam", and its design is based on the Zeta Gundam, following the Musha Gundam which was based on the Mk-II.
It has a small charger built into its body, and can perform electric attacks from the horns on its head. It also appears in the Hobby Topia arc, but is not seen to play an active role and is destroyed by a collective attack from the SPT (MF) of the Shikitai led by Gostello.
