Blackthorn

in addition to being a pirate, he is also a doctor for the crew. he has an extensive knowledge of herbs and medicine, and crafts medicine of his own, as well as many kinds of poison. often he tests the effects of his concoctions on small creatures before using them on larger subjects.

he lost his tail in an accident, but was able to replace it with a prosthetic of his own design, complete with a venomous barb.

he is always looking to increase his knowledge of medicine and anatomy, so he frequently seeks and reads medical books. scylla sometimes goes out of her way to get them for him as a gift!

when it comes to combat, he mainly uses his venomous tail or sometimes a poison-laced dagger as a weapon, but he is not as skilled at fighting as the others, and is a bit frail. he uses his wits and agility to come out on top.

has feelings for grimm, but is in denial about it...
