Dr. Gwen was the senior xeno-entomologist working for the bio-weapons division at Weyland-Yutani. Her division was working on a special pheromone extracted from a queen's royal jelly, that would theoretically allow a human to control a xenomorph through simple instinct. Numerous failures and budget-cuts later, Dr. Gwen's project was dismissed and labeled a complete failure.

As a last ditch effort to save her career, she spliced the altered pheromone with human DNA and injected herself with it, causing her to fall unconscious. Upon waking, she found herself in the arms of xenomorph, the same one she imprisoned and experimented on herself. With a newfound awareness, Gwen and the alien escaped the laboratory and vanished.

Endowed with incredible power and control over the vicious aliens, she forced her alien to grow into a queen, then commanded the queen to lay eggs. With her unstoppable alien horde, she continues to ravage the planet on which the laboratory was based, killing any and every lifeform foolish enough to get her way. Evading Weyland-Yutani's armies sent to capture her and even the legendary Yautja tribes how seek honor and trophies, she continues on her path of violence with an unknown purpose.....

Also she changed her name to Gwen SerpentChild because, you know, it seemed fitting.

I made this custom with Hope Summers: the cotume is hand-sewed and her weapons and mask are made from fodder. Her alternate hands are from Hit-Girl and Scarlet Witch.
