Canonpatibility? Oh boy...Let me start off by saying no one would get along? We have an emo with childhood trauma and self-destructive habits, yandere wolf lady, pomeranian, and human sonic with daddy issues, a bulb-headed alien supergenius with a goatee, skeleton catgirl, then like.....a plauge doctor hellbent on curing humanity on a disease he can't even explain. Yeah, OK buddy.
-049's and/or the catgirl killing everyone within the first five minutes, but assuming they don't Katsuki Bakugo and Scout are at each other's *throats*, and it's a continuous combination of insults and threats. The first time Bakugo is *f l y i n g* at Scout, though, he's finding some place to hide and you're only getting him out with a kiss or a BONK!
Despite the chaos of it all [and other things I won't name to keep this shorter than this would be otherwise], very hurtful things would be said, and when one of them(Scout) is crying, they'd all try and take it easy. A lot of my kins pretend not to care, but they do. A lot.
