Vance is a werewolf, dose not help with his anger issues and he can be very mean.
Bruce yamada is a kitsune, like the ones from teenwolf, he's calm witch works perfectly.
Griffin is a shapeshifter, he can change his appearance and body at will.
Billy is a poltergeist, he goes out to mess with people with his dog who is also a zombie.
Robin is a vampire, he and his family lived through a lot and he does drink blood on the occasion.
Finney is a normal human.. no he's not he's a witch he can see the dead and raise the dead, his powers has to do with the dead.
Gwen just like her brother is a witch, she can see the future and there's a sidetracke her dreams some times don't make sense.
The grabber is a Hunter, the only reason he got the boys is because he uses there weaknesses against them but he didn't know Finn was a witch.
Finn when he found out the boys died because of the grabber he decided to use his power to raise them back from the dead, but billy and Robin were kinda just stuck in a place they couldn't get out of but they still talked to Finney because there soul was kicked out of there body.
And boy was it a surprise for the grabber and the boys when Finn the human was not so much a normal human.
So the story goes the same but all the boys survive and the grabber gets killed by Finn.
Lets just say the boys are pretty much protective of Finn now, Vance and Robin more than the others.
Robins is whipped for Finney, well he was before the kidnapping but after god he's so down bad.
He is so glad he doesn't have to keep secrets from him like tears of relief glad.
Extra: Donna is a siren and I rest my case
