Pretty much what the title says. The muse wanted scribbly drawing, and it wanted Wheeljack, so, yeah. Has some 'Jack.
Copypasta from dA:
So. Kick in the Head!Wheeljack, to finally exorcise him out. His alt-mode is a Voisin Concept car, which I know nothing about except for the fact that it's gorgeous, and that it probably doesn't exist beyond concept sketches.
'Jack's a spindly little thing, with explosion-proof armor on his chest and arms, and little armor anywhere else. Once upon a time, he had an articulate face, somewhat like Ironhide's, but he blew that off. He's ridiculously flexible, and can wedge himself into the weirdest places to build or repair. He's actually got something in the number of 30 fingers on each hand, and a lot of those are a specialized tool of some sort. His Autobot symbol is on the back of his head.
Wheeljack is an engineer by day, and a dancer/performer by night. His default mood is laid-back cheerfulness, and he genuinely wants to make people happy. Even Ironhide, the only mech who really tests his temper and gets him riled up (he made Ironhide's cannons, based on that worthy mech's designs). He's quite the snarky bastard when he's in a mood. As far as battle goes, he tries to avoid it (that lack of armor thing) but when necessary, he can join his fingers into wicked-sharp claws, and he has what effectively amounts to a sticky-bomb launcher.
Not 100% certain I'm satisfied with him (his chest armor bugs me, among other things) but he looks pretty damn close to the mental image I have. Said mental image apparently being Defiance!Prowl, Jazz and Frenzy making a baby.
(his human version'd be about 5'6 or 7, little wiry Italian guy with too-long hair, a metric butt-ton of piercings and scars, and a lot of body fuzz :> )
