Vitamin C

Vitamin C is a Xenomorph biomolecule that originates from Proteus which is used by the XUF turn humans into Xenomorphs.

Vitamin C has been illegal in multiple countries, mostly HEF and EI countries. It has been used by Xenomorphs during multiple wars and conflicts to increase their manpower while decreasing human population. XUF militant groups usually set up large traffick routes where the compounds of Vitamin C are spread and use them to make the chemical and use it on humans. Xenomorphs have also disguised Vitamin C into normal products marketed by secretly Xenomorph-lead organizations to transform humans into Xenomorphs.

The transformation that a human undergoes when he is given Vitamin C is usually very slow. It isn't painful but it takes a few hours after consumption, and if it's a very small dose, it may even take days. When a human takes Vitamin C and transforms into a Xenomorph, the brain's memories are essentially wiped. There's Xenomorph-engineered compounds in the biomolecule that make it so a recently transformed human is fixated on Xenomorph conquest, making them inherently aligned with Xenomorph imperialism.

1960s Vitamin C scandal
When xenomorphs first appeared in Earth, Vitamin C was secretly used by them to transform people. It was never widespread until the 1960s, when the XUF experimented with long-term Vitamin C transformations. This experiment was conducted secretly Xenomorph-owned corporations which sold products that had specific doses of Vitamin C, meant to transform a human into a Xenomorph in about 1 year. This quickly backfired as Vitamin C doses were not fully developed and the people who were affected by it had extreme amounts of pain and brain damage rather than transforming into Xenomorphs, causing multiple governments to deem the dose illegal.

In the 1980s, XUF groups started to create trafficking routes where the compounds of Vitamin C were spread.

Post-Xenomorph reveal
After Xenomorphs were revealed to be real in 2020 by the Xenomorph Conspiracy Group, Vitamin C was spread more than ever. Multiple countries which were under the leadership of secret Xenomorphs started funding the spread of Vitamin C with usage of trafficking routes created in the 1980s, elevating the amount of transformed humans. Vitamin C continued to be used by Xenomorphs as a weapon until World War III, when Xenomorphs were ousted from Earth. Compounds of Vitamin C still existed after World War III but they were destroyed both by Egoist and HEF governments.

Use
Vitamin C is used to transform humans into Xenomorphs. It usually has a slow transformation speed, and past modifications of the molecule have allowed for even slower transformation speeds, although altering the transformation speed usually has side-effects and makes the transformation process fail.

Vitamin C was utilized in the 1960s by secretly Xenomorph-controlled corporations to try to transform the American population into Xenomorphs, although this failed due to changes in the transformation speed, which had been made way slower than usual, causing various side effects and destroying the transformation process.

The transformation process of Vitamin C is very painful and changes the appearance of a human to look like a Xenomorph and gain Xenomorphic attributes (such as shape-shifting). Newly-transformed Xenomorphs have a fixation on imperialistic conquest due to compounds in the biomolecule that affect the brain, the part of the body which is affected by Vitamin C the most.
