A member of a mysterious alien species, Hydra has never known her parents, family, or any others of her kind. Her age is unknowm.
She works as an assistant to Lithium in his laboratory.
She appears to present as female or at least feminine, and she uses she/her pronouns. Due to the lack of information available about her species, her sex is unknown.
Her entire body is made up of tentacles that can fuse and unfuse in various configurations. She seems to maintain a biped body plan due to ease of use and for others' comfort. Flesh texture is squishy, like a mollusc's.
Often seen wearing scrubs, medical gowns, gloves and/or medical masks.
Perhaps due to how biologically different she is from the patients she encounters, she expresses no squeamishness about assisting Lithium in his unethical procedures and experiments. However, she often takes pity on their test subjects after the fact and helps to nurse them back to health, assuming there is anything left over to nurse.
She appears to obey and respect Lithium's wishes nearly unconditionally. She has been known to offer herself to him as a test subject. The true nature of their relationship is unclear.
Quiet, introspective, and calculating, she has an incredible capacity to absorb and retain new information.
Her biped form is a maintained one, meaning that any facial expressions or body language she displays are deliberate and for the purpose of communication with others. She rarely smiles or expresses any emotion outwardly.
She is neat and tidy to an obsessive degree, often cleaning up after Lithium's messes.
During her off hours she enjoys reading literature, cooking, drinking tea, and working out.
