out of the villains: muscular for sure (even if mac joined post kamino but before overhaul arc). hanabata is also on their ick list, as well as skeptic. lady nagant is on it too. but afo! mac hates afo!!

heroes: being biased towards dabi, endeavor is a given but they aren't vocal on it. star and stripe is fair game since they are american ("this is Captain America erasure. he is AMERICA'S ASS!"). hawks is on thin ice due to their trust issues (and stealing all the kfc, which is another gripe they have).

can't really say anything about the students other than they think ua using kids in the war(s) is scummy. they feel awful about dabi's siblings too, especially shoto. he's just a baby.

Dabi: Mac hates to admit it, but dabi does have rizz and is very attractive. Yet his smarmy smirk and general asshole behavior tested Mac very day. Dabi irritated them, yet mac was falling for him more and more.

Compress: Mac met Compress at one of his magic shows prior to the start of the series (at least, before the league formed. I have lore that he probably did heists and all that and still was an entertainer... anyway). They were neutral, found him amusing. Then he calls them up on stage and they're suddenly so shy, yet out of nervousness does play off of him really well. They had a fun time at the show.

But that was the entertainer.

After they escape the shie hassaikai and found sanctuary with the league, Mac did recognize him (the mask, top hat, and bolo were giveaways). He was just as charming as he was at his show, but this was as close as they got to the real him. And they were smitten.

i hate saying it, but twice. not that twice isn't nice at all! twice was-- and will always be-- a total sweetheart. he's just a lot for mac to handle at first. his constant habit of contradicting himself confused them at first, especially with their bad brain and being neurodivergent themselves (not understanding social cues and all that). mac is also a very reserved individual and doesn't like being open about anything ever. it takes a while for them to understand twice. mac misses him dearly too because he didn't hesitate for a second to consider them a friend and that meant a lot.

there's also shigaraki but that's more him being a whiny little gamer rat man (affectionate) and not yet a proper leader, especially in the wake of afo getting arrested (which is when mac joined). but i like to think, since shigaraki is an aries and mac is leo, things do even out. if spinner and shigaraki get along, so can mac.

toga would be one too, but mac does have a nephew around the same age as toga so they can handle her. while mac is no replacement for big sis magne (miss her too), they do try to be that sibling/auncle role model for toga so she can gush about her crushes. if compress is "dad" of the lov... then mac can try to follow in his footsteps.

had mac joined earlier, muscular or moonfish would be a top contenders of people they wouldn't like being around. especially muscular. i don't need to say why.

if i had to pick anyone, probably spinner.

they know the strife of being from a backwater town, and being a couple of country folk. while mac is american (and their town is actually a college town despite being small in their eyes), they can relate to how spinner grew up. both were ostracized albeit for different yet similar reasons. mac was an alt kid growing up, and living in a conservative, rather religious town in the southern united states is never easy. they were called cruel names, including "mutant" despite not looking like a traditional heteromorph. mac, for most of their twenties, was also a recluse until they managed to break free and go to japan. and there is a common interest in video games but mac had very obscure ones that no one gravitated towards.

before her death, mange was also growing close to mac too. trans siblings and all.
