Genetic Jean was discovered in a lab where women were cloned and conditioned for prostitution. PAWN* members rescued her from a liquid filled tube which kept her in stasis during the cloning process. Most of the cloned women were terminated by PAWN, but Jean was allowed to live since she was fully developed and awake at the time of the raid.
Jean is a combination of two clones fused into one. Her genetically enhanced muscles lack the bulk of a body builder but have its strength. Also, her heart and lungs have been increased thirty percent and her bones strengthened to support the enhanced muscles. Yet, despite all these advances, she maintains a womanly physique, providing an illusion of a normal woman, which allows her to surprise her enemy with super speed, strength, and flexibility.
Having the intellectual skills of an eighteen year old, Jean struggles in adapting to the complicated world. Knowing she is naive child and vulnerable to attack, Double Eagle, a employee of PAWN*, teaches her self-defense.
*P.A.W.N. -- Practical Assimilated and Weaponized Nephilims* -- regulates human cloning and DNA altering. The organization's mission is to apprehend mad scientists and their creations determined to be threats to the public. For example, it would seize genetically altered beings in the same way that dangerous animals are illegal to have as pets.
*Nephilims are mentioned in the Holy Bible. They were giants that lived long life spans. The Holy Bible states that Adam, a Nephilim, lived around 900 years
