This is
a posable action figure of an item from the Gundam universe.
Bandai's "Kado Senshi" (lit. movable warriors) are smaller versions of their highly-popular "Chogokin" die-cast metal action figures. Previously we had the Zeta Gundam, from the series of the same name. This time we get the Type 100, aka Hyaku-Shiki, the bright gold-colored machine flown by Char. This item comes with great "wepons" (sic) such as the huge "Mega Bazooka Launcher" gun.
