While an animal/human hybrid is common, a fantasy animal/human is rare. So not many people will get it, but Jayden is one of them.

Jayden is a pretty chill hydra girl, but can get pretty violet when angry. When she transforms, she has one head, but actually has her head chopped off, and unsurprising, three heads pop off and Jayden gives them a name: April, the shy one, and Penny, the trickiest one. Now, she doesn't want any of her head chopped, not only that it painful, but she also knows that more heads will grow in and she's fine with three heads.
