Figure: Agent Helix
Head, Bracers, Greaves: Marvel Universe X-23
Painting over that yellow has proven far more difficult than I expected. I cannot get it to stay on the shoulders/elbows.
Laura Kinney has no memory of her past. She was given her code name first, and her civilian name as almost an after-thought. A deadly assassin on her own, but given small blades and up close work? She's a whirlwind of flashing steel and blood. She has been genetically enhanced to a point where her sense of smell is close to that of a bear, and her reflexes are akin to a Mongoose. Able to get in quick, deal damage, and dart away before a counter strike even begins.
Whatever compunction she has about killing a target is washed away if said target is some how dosed with a "trigger scent". Known as "Trigger 42", this scent is not found in the natural world, and is only used when her handlers feel like she needs motivation, or to cause a scene. Once under its influence, she is a berserker. Killing any and all in her path towards her target.
