Hero World Green Lantern; you spin a dial on his back and his staff-holding hand rotates to spin his weapon. The best part though is that Atrocitus has a unique weapon with his Red Lantern symbol branded on it - it isn't just a re-color of the GL staff, which would have been an easy way for Fisher-Price to save a couple pennies and few kids would have noticed anyways. In a world of toy parts re-use, that's a nice touch as well.
On the packaging his shoulder pads are colored red, but here they are black. I don't know if that's a mistake or if they will all be released like this, but it's a minor issue and would not have dissuaded me from buying him either way.
