Poorly.

Well, it’s not all bad. What is initially a confusing and jarring mass of meaningless information to Megatron quickly becomes actual sensory information, and by the end of the month he spends kickin’ back in Spike’s brain they’ve figured out how to work together. I mean, it’s not like they have a choice otherwise.

Fortunately, Megatron mostly gets to sit back and kind of just…observe, but the experience is still a shaking one for him (and while he and Spike still absolutely hate each other afterwards they do understand each other a lot better).

Food? Food is horrible and humans are bad at digesting things. Megatron, of course, can also like…eat and digest stuff like rocks and mineral deposits but Spike’s need for food and tendency to eat, well, like a teenager? He isn’t a fan. He does enjoy the experience a bit more after a while because he is experiencing it through Spike’s body- and humans usually enjoy eating. His worst experience with food is either when he endures Spike eating cheese pizza despite being lactose intolerant (”IT’S WORTH IT” “WE ARE IN SO MUCH PAIN YOU FOOL”) or when he’s in control of Spike’s body and in a desperate bid for “fuel” as Spike is growing exhausted he drinks most of a pot of coffee.

(And subsequently burns down a MECH warehouse it’s fine don’t worry about it)

Spike’s dysphoria is a source of great discomfort and curiosity to him in turn, and part of their mutual….not really respect but their mutually assuring boundaries between each other is that when Megatron complains about being in Spike’s body? Spike complains right back. Megatron might not understand sex/gender fully by any means, but bodily dysphoria isn’t unheard of among Cybertronians, and if nothing else Megatron’s insistence that one’s body is absolutely meant to be shaped to the form that makes it’s holder most comfortable is very reassuring to Spike.

And Spike’s social life?

Megatron’s pretty sure they’re being attacked or having some manner of heart failure when they see another student Spike has a crush on and his heartrate s o a r s. THERe’S a lOt of ADREnalINE GOING ON WhaT IS HapPENING?!
