Berserk react to y/n as lain from serial experiments or nikaido from dorohedoro or another idea black dragons from Tokyo revengers react to yandere simulator or slashers react to American horror stories or fyp ?
hmmm, maybe transformers? Like serials (prime, animated and etc) or films… Oh! Steven Aus or others universe au, smt like that. Films like Cloverfield or some other horrors Marvel and DC in this case very big (deadpool, venom), maybe manhva(?) and comics(?) Like bro, this depends on you, what you watched and known very well 👌 Will be wait whether this will bring lol 🎉🎉🎉
I uh don't know if you know Undertale, the game. If you don't then oh well, you don't have to keep reading this. But if you do, just reacting to all the monsters or even some animations[Like Funny Bones and such], who knows even some comic dubs. Or maybe even Undertale reacting to other AUs, but I don't have any other ideas than this. Sorry if you don't know, or just don't feel up for it. Peace✌
