Itís been ages since Iíve actually drawn him. This is just how I see him in the canon of the game based on all the dialogue and whatnot honestlyÖ Also, something I added was that he only has one optic that seems to work properly, which is why one is dimmer and just looks more normal. His working one doesnít even work that well alone and the other one is practically blind, and this is why he also needs to use the glasses. (sort of a reference back to his one optic as a core)
You may wonder whatís the purpose of having such a dysfunctional robot whoís damaged enough to not even walk or even see properly by himself, but I think you just answered your question there. Heís Wheatley. Heís just a crippling core. His whole purpose is to burden you and bring you down. Itís not his intention, but he physically and mentally will infect you down to his level. Like a tumor.
Also, plot twist:
Crippley becomes NB.Oooooooh
Also, it was drawn on paper, but I touched it up way more than I thought I would in photoshop.. derp.
