Don't talk to me until I've had my coffee

Roar steampunk style. You know, more than he already was.  He's addicted to caffeine and smokes a caffeine pipe almost constantly because he hates sleep. He usually stays up 3-5 days at a time, if he gets enough caffeine, if he doesn't he passes out right away
And he's probably the angriest person in existance
I also aged him up 10 years in this AU (to 24) since a 14 year old mechanic thats living on his own and is addicted to caffeine would make no sense in this universe
btw i miiiight do a comic on this au in this style so. Like this was literally a tester for a new style since im looking for one that would work for a comic pff.
