G.E.M., short for Gokai Excellent Model, is one of MegaHouse's core premium figure lines, a pre-painted PVC series that ranges widely across anime but is especially known for giving shonen and male characters the polished scale treatment. Naruto, Demon Slayer, Spy x Family and many others fill the roster.

The line has spun off several formats, from the palm-size Tenohira pieces to the effects-heavy Remix entries, around a core of standard premium figures.
