Here are some quirk ideas I can think of that you can freely use in your fan fictions without credits, and I don't own any rights related to MHA/BNHA content... (It will be much appreciated if you give credits though, and even if not given it is fine. If credits given please message me, I would love to read it...) This are some Quirk ideas I have come up with. I think you will like some of them and you might have suggestions to improve some of them. Feel free to comment about it.

Random quirks that may help in your writing! If anyone does end up using one, I'd like to read it! *Art isn't mine*
