This is a posable action figure of a character from science-fiction/anime.
The "Actic Gear" series from Takara consists of great little 1/48 machines and their weapons -- sort of a competitive series for Bandai's HCM Pro, maybe. This set includes Fatty, Catapult Launcher, spare hands, Fatty information card, and a display nameplate. Though it stands only 8 cm tall, Fatty can transform completely into "down form." Lots of palm-sized fun, and at a reasonable price!
