I've been thinking role reversal Togachaco(yes it's with a C, fight me) and I just really like the implications with it, Ochaco could a broken villain in a similar vain to Himiko but I'm thinking more she was struck with trajady which could trap her in villain I also imagine she'd be a theif with dreams of luxury, Himiko as a hero could be interesting I imagine she'd be fostered by the hpsc like Hawks but because of her quirk they'd keep her on a tight leash, managing and limiting how much blood she gets and such, she'd only stay with because saving people is nice and it's easier with them than at middle school, and they both of them are so much closer to neutral territory as opposed to in canon as neither have would likely have any close friends or allies to keep them tethered to this life making it easier to bring them to neutral territory that and regardless Himiko will always have she destructive tendencies and Ochaco will always have her heroic tendencies, it is what it is and al lot if this came from over analyzing the one fan fiction I read on this, I may be back for more...
