I think if AM would get a physical body, one of the first things he'd try are one of the most damaging things to a human body in a long run. Cigarettes, alcohol, drugs in general, so on. Consequences? Nah, he doesn't care. I see him like an impatient type to risk and rush things — childish, in a word. But that's understandable, given the fact that he was trapped in sensory deprivation for decades now. No wonder he simply wants to feel good for just a scrap of seconds. Do you remember that Futurama episode when Bender got a human body? Yeah, well, and then he died pretty soon. That's how I imagine AM would handle his body, as well. Like we can't expect him to care enough about his physical manifestation, as long as it can get him high, at least because he knows nothing about responsibility. He probably doesn't know how to, since he's never taken care of anything before: he used to get his way through physical power, so I suppose he would be a pretty reckless one. Besides, maybe he's a bit of a masochist. The pain is better than no senses at all. Perhaps he'd get experimental about this, given his "fantasy" and knowledge. Maybe if he could, he would have a million of vessels in store to switch between and just pick up a new one once the first one becomes dysfunctional. Also, people usually draw humanised AM more masculine leaning (at least because his voice is literally Harlan Ellison, duh), though I think he'd want to experience everything, including a female form, too. And I guess a lot of people have already noted this headcanon, but it won't hurt to say it again: sensory issues and sensory seeking behaviours. Now, I'm not sure what kind of textures exactly would make him uncomfortable and which he'd like (my first thought was water for some reason, lol), but I think that everything would overwhelm him at first, because "THE AIR TOUCHES ME". I can't help it, he just gives me a bit of autistic vibes... And maybe DID. And maybe- damn, he might have a bunch of disorders, now that I think about this. Which kinda makes me want to comfort him more. Anyway, he's a babygirl.
