>>7030229>>7030265That's a battroid VF-1J from the Absolute Chogokin (aka Chogokin Katamari) line! It's basically just a hunk of diecast, no poseability of features whatsoever, but it's a neat desk rider. The 1J was a convention exclusive but it's still fairly cheap to throw into a larger Mandarake order or something.
