I know there are several but I'm looking for a definitive list of all the genres that end in -core. Love 'em or hate 'em, they're here to stay. I'm asking here because r/metal and other metal forums aren't female or -core fan friendly.
There are really an infinite number of genres, you can create one yourself, imo. Some other recognizable -cores are electronicore, mathcore, prog metalcore, although they are arguably subgenres of metalcore. You will find a lot of punk-metalcore crossovers to make new core subgenres. r/metalcore might be a good place for you.
I'd say this is a fairly definitive list, plus some extras: List of hardcore punk subgenres.
However, new subgenres are always being created. Hope this helps!
