Looking similar to the RX-78-2 Gundam, the Musha Gundam differs from the original due to its Samurai Motif. The mobile suit is armed also with powerful weapons including the Sankoumaru Jumonji Yari, a powerful spear that could pierce through tough mobile armor. It also has its default weapon, the Nichirinmaru Katana and two Denkoumaru Naginata. Aside from its default close combat weaponry, the Musha Gundam is also equipped with the Tanegashima gun for long ranged combat.
Since in the SD Gundam series, the Musha Gundam is a living mobile suit and somehow is like a real warrior, this is the reason why the unit has no pilot of its own.
Musha Gundam first appeared in "Plamo Kyoshiro". In the story it is an original Gundam created by Shiro Kyoda for the showdown with Shigeru. The original design of the SD form Musha Gundam is credited to Koichi Yamato and Craft dan representative, Yasui Hisashi. With a growing fanbase and raging popularity, Musha Gundam products like the 1987 SD Gundam Gashapon MK13 and in 1988 BB Senshi No.17 were created. The products were extremely popular with school children, and thus Musha Gundam graduated from SD Gundam to a stand-alone genre.
