i'm w, and i'm new. bringing in two three characters from the jump.
first up is marvel's betsy braddock a.k.a. psylocke. not to be confused with the new psylocke, who is kwannon. betsy is mostly from the comics, 616 universe, but please see her app info to note the little au twist.
then we have a younger version of molly weasley prewett. she is pulled from around november 1967, meaning her 7th and final year at hogwarts, before all hell breaks loose with the first wizarding war. you'll have to excuse me, i'm a bit rusty from my harry potter hey days. it's been ages since i've read the books or watched the movies and i'm afraid i haven't kept up as closely with the pottermore and beyond content due to all the usual jkr disappointment reasons.
eta: annnnd because i am easily enabled, i also bring in peggy carter of the mcu!
i'm also only a bit familiar with the doctor who/torchwood fandoms. i watched the show back in college so i know of mostly the ninth-twelfth doctors.
