Name: Samantha Rose
Alias: Richard Sinclair, John Doe.
Human Height: 5’ 8”
Unknown’s Height: 6’2”

She’s has a curvy figure but well formed. In the form of Unknown she takes on a male shape losing the curviness for fit agile form.

History: After his sister's death by a dose of bad drugs Richard went on a personal crusade to find the people responsible. In time he wormed his way to the manufacturing location where he was captured. After being tortured he was injected with a lethal dose and dumped at a warehouse in Iron Port. It would have been the end of him, in many ways it was.
That is when fate got involved or was it blind chance. Falling into orbit of earth was a mass of crystal based life forms that drift in orbit of the sun. The mass is a collection of organisms functioning as one only complex enough to move to avoid danger. This one drifted to close to earth and got caught in its gravity the magnetic field damaging it as it fell. Wounded and dying its body normally a black blob was changing color a light purple blob of goo.
That when the dying Richard noticed it curiosity or just dumb luck. Richard fell near the blob his bleeding hand squished the mass. Enough of the alien cells entered his blood stream that it figured out it could hide from the magnetic field in Richard. The last remaining living cells of the blob soon fled into the body of the man as the rest melted into a puddle of slime.

The body wasn't safe just safer there were contamination do deal with. A fight of survival took place as the microorganisms forced the poison out. The Alien cells then began evolving adapting to the new norm as they replaced the damage cells of the host. The man was now part of the collective and the being known as UNKNOWN came into existence.

Time went on the longer the lifeforms lived in the body the more it absorbed till there was nothing biologically left of the man once known as Richard. Just a faint echo of fears and doubts, those doubts lead him to work for a group called A3. It was on one of the missions that events changed Unknown in even more ways. Having been exposed to electrical energy beyond his abilities to absorb it a second Unknown began to emerge. Fear that this new entity could become something monstrous drove Unknown to try to destroy the budding life. A Hero and member of the team named Lucent Dawn gave him a healing compound called Liquid light.

The Liquid Light had stunning effects on the child. It absorbed the liquid light and emerged taking the form of a baby girl with empathic powers. Now technically a single parent Unknown took the form of a woman named Samantha Rose. The child was given the name Crystal Rose.

Powers: A shape shiftier Unknown can take on many forms twisting and even surviving being broken apart. If the connection is lost then the smaller mass is no longer recoverable and could grow into another Unknown. Unknown strives to make sure she doesn't lose any mass.

Unknown can absorb energy, light, and heat. Having first evolved in space it feed directly on light, energy, and radiation from the sun. On earth he still needs to eat to compensate for the reduced energy caused by the earth’s atmosphere and Magnetic field. Now it has adapted to earth it no longer dying by the Magnetic field.

Weakness: The crystal lifeforms short out when exposed to water or ice. When in the human disguise it has some resistance but in the altered state of the black mass it can easily be harmed by water and ice.
