[@olcharlieboi] I'd say a quirk that clashes with the quirks of other students would be interesting. Eventually being forced to work around the conflicting nature of the quirks. And personality clashes are just as good, because BNHA wouldn't have been the same without Bakugo, and he clashes with basically everyone. Also if you need a quick recap of what's happened so far send me a DM. I'd be happy to help you out.
