Portal 2's Wheatley doesn't really have a body. He's the robotic equivalent of a floating head in a jar. Which makes it easy for him to whizz about the game's levels, but makes it hard to craft a decent action figure out of the guy.
So custom toy builder KodyKoala went and built him one. Using a Wheatley key chain as a base, he took parts from other figures and constructed a glowing, Portal-gun-equipped torso and limbs, rounding out the figure with his own Companion Cube.
