(History of character is being rewritten.)
Xenomorph: Tail with retractable venomous blade, clawed fingers, rough skin texture plus features and killer personality. Speed. Also has Facehugger tongue.
Predator: Tracking skills, knowledge to recognize and make traps, good with inventing, smelting, and building. Has ability to adapt to surroundings fast. Strength.
Human: Body structure and ability to speak English... though broken English.
Her own: Different pair of Xenomorph back spikes, green eyes and 2 stomachs.
In the bottom right corner is her tongue and a front view of the tip of her tongue opening wide. The fangs fold inwards to conceal completely.
Raven does not have a real gender since she does not have any human-like reproductive organs whereas she does have small breasts, but no nipples for example. "It" takes more after a Facehugger. In a way... she has a human female's figure crossed with slight hints of a male so I call her a girl.
