This is a posable action figure from the Revoltech series.
Here's GR-2, nemesis of our hero Giant Robo! This Revoltech version of GR-2 is based on the 1992-98 OVA series, and was sculpted by the talented Katsuhisa Yamaguchi. As with all Revoltech figures, GR-2 comes with tons of "revolver-joints" that make possible plenty of poses and playability. GR-2 comes with a rocket bazooka, rocket bazooka support arm, option hands, and a display stand to help you show off the astonishing posability of this bad 'bot.
