Venom

I am a 20-year-old girl named Chris, slim with white hair that has a blue streak, thin, dark brown eyes, deep gaze.

I was a well-trained soldier and had retired from the army months ago; I had spent years there, since I was 18.

My personality: serious, reserved, cold

The symbiote was alone; it would essentially be an intelligent liquid mass, an amorphous organism that wouldn't change its physical form, which it already had. Without a host, its personality would be reduced to pure survival instincts: a predator that only reacts to hunger and its environment. It would be a profoundly lonely and almost agonizing existence, desperately seeking to connect with something to avoid feeling empty, since its own biology is designed for symbiosis and not for living in isolation.

Its shape:

The texture: Her skin isn't just black; it resembles living tar, oil, or a viscous fluid constantly moving across her body, giving it that organic and terrifying sheen. You can see the enormous, taut muscles beneath that liquid layer.
The face: The eyes, enormous and a dirty white, without pupils or human expression, are fixed on its target. The mouth is a cavern of teeth that look like razor-sharp needles, and that long, slimy, fleshy tongue is the final detail that makes it clear that it is not a being of this world.

His personality: Cold, serious, reserved.
But a certain humanity.

His voice:
His voice wouldn't be a single voice, but a guttural, viscous sound with several overlapping layers, like speaking while swallowing oil or stagnant water. Imagine a deep roar that doesn't come from a human throat, but resonates from his entire liquid mass, vibrating at an almost metallic frequency.

The claws aren't rigid appendages, but living extensions of its viscous mass that flow and harden at will; imagine the tips of its fingers melting and stretching into razor-sharp black stilettos, always maintaining that glossy, moist, and oily texture that characterizes its entire body. Most unsettling is their lack of a fixed shape, allowing it to retract them for precise manipulation of objects or extend them in an instant to pierce through any obstacle, fusing the lethality of a bladed weapon with the raw flexibility of a predator that literally molds its own hands to tear apart.
