Manga: is there a special name for the manga characters that can attack with their hair? Gonna try to make this a TTRPG class or at least a variant for witches.

Hmm. I have seen those kinds of attacks. I think its certain type of Youaki. Perhaps Spider Yokai hair attack. But doing a google, here is this:

Harionago

Thanks!

Are there any other weird ways of attacking or defending in mangas?

Tillie : power from chainsaw man uses blood, forms it into different objects

I love this idea so much

I have seen JRPGs that have one of the support characters be some kind of chef and use cooking related attacks and buffs. But the manga/anime trope of "pretty/popular/powerful girl whose cooking is so bad it's scary" would be a weird twist on that.

Been rewatching That Time I Got Reincarnated as a Slime, and characters that manage to not die from Shion's cooking gain poison resistance when they finally recover.

Cook sounds good.
