Wheatley
I'm Wheatley! Ya know, the lovable British robot core, Wheatley! You can see I'm a robot from all this metal. And wires, those too, wires. I... don't have any limbs, let's get that out of the way, I know you're thinking it. I'm just this sphere with a blue eye, that's it, really. I can still roll, though! Since I'm a ball. And, ya know, rolling's pretty fun, innit? Some people say I'm a moron, but trust me, I am NOT a moron.
