Kyle Rayner from the cover of Green Lantern New Guardians #0. Just call him Torso Boy.
In fairness, I did alter the picture slightly. I removed the background … and the leg that was emerging FROM THE MIDDLE OF KYLE’S CHEST. I wish I was kidding.
I’m guessing the other leg was lost in a tragic art mishap, along with his left arm.
Between this and the Catwoman #0 cover, it’s obvious that Guillem March is in desperate need of some remedial anatomy classes.
