This is an injection-plastic kit of a science-fiction/anime item.
Introduced in the "Super Robot Wars OG: Original Generations" PS2 game, Rein Weissritter is a mutated form of Excellen Browning's Weissritter after the mecha and its pilot were captured by enemy forces. This sharply detailed snap-fit plastic kit of the biomechanical Personal Trooper comes molded in color, with its face and wing parts prepainted. Upon completion, the mecha will stand 15.5cm tall and feature ball-jointed articulation, including in its flexible wings. It comes packed with its signature Howling Launcher that has a "tail" made of bendable material. (The stand shown in the second and third photos below is not included.)
