HELLCAT
whenever I see her, I can't help but see Buffy the Vampire Slayer. she just seems like a Whedon character; her bubbly personality and relationship with some supernatural villain. so, if I were to revamp it, I would just start there. Her mother would still make the seemingly fictional accounting of her life into a popular teen novel. but all of it would be her real high school experience. Daimon, Buzz, Hedy would all be present and accounted for. and their entire town would be the focal point of strangeness; alien invasions, demonic possessions, mad science, etc. I would try to work the Salem Seven into it somehow, as well. and a lot of the stories would be told in the past; to allow Hellcat to do other standard crimefighting stuff in the present. she'd still be have her gymnastics background and magical warning system. but I'd also make her physically stronger/more durable to allow her to better defend the town's population. I might also have Kyle Richmond be the regular dude in her circle of friends who longingly wants to be a costumed superhero/be part of that world (which he, eventually, will be).
CLOAK AND DAGGER - never liked the characters but I want to. they have cool code names. anyways, a lot of this will be informed by Netflix Iron Fist. i liked the angle they gave to Colleen Wing. so I'd have Ty and Tandy be students at a martial arts dojo (pick one of Marvel's martial artists). they'd still be runaways; the dojo would be home to a number of "lost" individuals. but there'd be a similar element to whatever organization set up the dojo. Ty and Tandy would be some of the only ones to survive the ceremony that gave them powers. I might make a connection between the two and Martin Li/Mr.Negative; to set up the later stuff. I'd get rid of Ty's stutter. he'd still have been bullied. Tandy would still enjoy dancing. they'd still see protecting runaways as one of their main goals. they'd also tackle the drug trade in the area. the sect that gave them their powers would also be in the narcotics trafficking business.
