Last year Philando Castile was murdered by a cop in front of his daughter. Could a version of Blizzard that combines elements of that with the general mood of Mister Freeze's story in BTAS work as sort of the Anti-Riri? Basically a girl's parents are murdered by cops, she seeks revenge using her genius at cryogenics, and Riri has to stop her while nonetheless loathing the men she's seeking vengeance on. Riri can't allow murder, yet at the same time it's disgusting that these men are still on the force and might kill again.
Villains you sympathise with are often the best villains, but I dont like the tiresome habit that - because weve put a person of a different gender in a role - all of the classic characters villains also have to be flipped.
