Weapon Hex

After gaining the power of the Infinity Stones, Gamora sealed the souls of the universe within the Soul Gem. In order to incapacitate its inhabitants, she additionally folded the universe in half, merging every soul with another. This course of action accidentally resulted in the creation of Warp World, a pocket dimension where history was rewritten and adapted to the fused beings. Inside Warp World, X-23 and Scarlet Witch were merged together into Weapon Hex.

Eighteen years prior in this world, the twenty-second attempt of the occult/scientific sect known as the Evolutionaries to create a vessel for the demonic Mephicthton had failed. Co-lead scientist Sarah Kinney posed the theory she and her lover Herbert Wyndham needed to stop trying to create a perfect speciment, but instead make something flawed. To this end, Sarah herself decided to conceive their next subject. Combining their best enchantments and enhancements, Sarah was impregnated and gave birth to a mutant girl, whom Sarah named Laura. Much to Herbert's chagrin, Sarah cared for Laura instead of treating her like an object. Sarah additionally nurtured Laura's humanity and empathy, whereas Wyndham tried to convince her that she was a weapon who had evolved past such values.

The following years, Laura was trained in combat by Hellhound to become a perfect assassin, Weapon Hex.
