Wheatley

Wheatley is a plucky, lovably idiotic Personality Construct, pulled straight from Aperture Laboratories to satisfy the whims of the DarkRealm.

Skills and Weaknesses
Wheatley can plug himself into various sockets. Which only really helps in the Aperture Labs seeing as the walls were designed to move whenever required to. He is also so stupid that he cannot comprehend the idea of paradoxes; therefore he cannot malfunction from one being input into his system.

HOWEVER, he's also incredibly stupid, as the previous paragraphs would suggest. His idea of infiltrating a computer system is rather... physical, for example, 'hacking into a door' by ramming himself into it as fast as possible. If there are no rails to latch himself onto, he cannot move unless someone carries him.

Appearance
Wheatley resembles a medium-size battered silver cauldron, only with a blue glowing eye and a bunch of faulty programming in its core. He speaks quickly and eagerly, and has a British accent. That's all that needs to be said, really.

Personality
His 'mind' full to the brim with ideas, Wheatley usually only wants to help you. Shame his ideas are so bad they'll more often than not endanger the both of you. He's an awkward little AI with quite a bit of anxiety over certain events and people, but if he's not plugged into GLaDOS' body, all chances are he means well. However: it is shown that he considers himself above humans; speaking of which, he lets his feelings slip easily. He apologizes far more often than he needs to, and is very talkative. Oh, but by no circumstances call him a moron. He doesn't take to the idea so well.

History
CONTAINS PORTAL 2 SPOILERS.

Wheatley was part of the great plot of Portal 2. He was responsible for waking Chell (supposedly the only test subject remaining alive) up, and took over the facility after GLaDOS was accidentally restarted. Unfortunately, he couldn't quite handle the power, and thanks to the faulty programming in GLaDOS' body, he went power-mad and nearly destroyed the Aperture Science Facility - till he was exiled to the moon - but recaptured by one Doug Rattmann after he escaped the labs himself. The two were then dragged into the DarkRealm and forced to read My Immortal that one time, and both will attend further MST events.
