Okay, so if this is in the wrong place, please tell me. He's not actually from anything, so I guess it'd be OC, but there's no brand selection for that... So the chest and hips are from Marvel Legends Beetle. So are the big arms, which are actually the legs from Beetle. The smaller robot arms/hands and the big hands are from 3A Popbots, which are super cool because the fingers are fully jointed. The neck collar is from the Tomar Re Green Lantern, the head is a 3D print from Shapeways. The large arms are attached on the back using a dremel and gluing in Bionicle joints to connect to the arm joints. The figure's legs are from an Evangelion. Finally, the cape is the bottom part of Keanu's trenchcoat from the Matrix Chateau diorama. Plus lots of paint. This was the first custom I ever started, and I actually put him down for a good long time, until I found the frog head and got inspired.
