It's the goobers! (also, all elves can be qualified as weird cats because I said so)
To add some headcanons-
Dakota Cole:
100% has undiagnosed ADHD. The Cole Serum made his hyperactivity SO, SO MUCH WORSE (bro cannot sit still and think otherwise he will go fucking feral)
Short version as to why his powers fuck him up: His powers straight up turned off the limiter in his brain that prevents humans from using 100% of their strength, and Dakota, having normal human bone and muscle density, is not physiologically able to take that sort of punishment, and it causes his strength to tear his body apart
He actively has to put conscious effort into not using his full strength, if he's startled or angered, that can cause him to lose that concentration and break whatever he's holding.
Post-surgery, he has to kind of adapt to not having to do that anymore and sometimes will be overly gentle with handling stuff without thinking about it.
He develops demon traits when feral/chaos style mode
William Wisp:
Bro has no body heat
He doesn't feel pain anymore, and when he yelps, it's often out of shock or horror because having a bone coming out of your skin is very bad.
His eyes, when not illuminated from the side or front, tend to resemble the glazed over eyes of a corpse.
He has a fear of bugs after... a certain incident in Deadwood. He also avoids churches half the time because of that.
He doesn't sleep anymore.
He often has to stretch every hour or so when he's sitting still for long periods due to his muscles being very susceptible to getting stiff (read: Rigor Mortis), when he forgets (which is often) his body locks up a bit and he has to make more of an effort to force his muscles to move.
Post-Surgery, he has a slow heartbeat (3 beats per minute)
Vyncent Sol:
Fauna's elves evolved to fill a similar niche to humans, but unlike humans, Elves are Facultative carnivores (carnivores that can eat and process plants) and primarily eat meat.
Immune to most poisons. Unfortunately this carries over to sedatives and medicines used by earth's organisms
He had his first taste of alcohol at around 10, and is quite comfortable around it (and may partake if asked, tends not to because of US-style drinking laws- aka 21+)
Can hear the same frequencies dogs can. Do not use a dog whistle around him he will stab it.
DO NOT use a laser pointer around him. Last time they messed with one, Vyncent left multiple gouges in the floor from stabbing at the laser dot.
