(I'm running with the assumption it's okay for me to join, here's a brief synopsis of my characters and then I'll jump in.
Henry Jekyll/Edward Hyde: I made an adaptation of them and rolled with it. They use they/them pronouns and identify as genderfluid. They are basically gifted child burnout personified and are severely depressed, using substances as a coping mechanism for their problems. It is unclear whether they are one person in two bodies or Hyde being an extension of Jekyll, but they prefer to be treated as their own things when they get the chance as Hyde is incredibly mentally removed from basically everything Jekyll is. Hyde cannot science, but tries. Jekyll can science, but doesn't. They are currently stuck as Hyde, and can sometimes transform at will, but not as of the present. Jekyll is extremely tall, Hyde is unusually short.
Coralynn: A messed up science project that lead only to shame and misery. She is, effectively, a corpse. Except brought back to life through complicated reanimation stuff. She has few memories of who her body once was and doesn't want to know. Mom friend, but wine mom. Holds a grudge against her creator for making her a miserable monster, like all the others Victoria (creator) had made.
Hope that's good)
Edward Hyde, or… who were they? They were the short one, yes, still the short one. And where were they? Somewhere they shouldn't be, they reckoned, the place looked too fancy for them. How smashed were they? Enough to black out, at least. And find themself in a nice, nice house nothing like anything they'd seen before. Why not look around? They stood up, and immediately fell over. It looked like a kitchen, to them, and they were sitting in the back of the pantry.
Coralynn woke up in a bed that was not hers, in a room she had never seen before. She got up and began to look around, finding the door and shambling out into the common area. When she found others, she hid, not wanting them to see her monstrous form. Not wanting them to react like all the others had, with fear and violence.
