Art by Calikat, this is Topaz Everett as an X-Kat. Wearing the uniforms seen in X-3, her powers for the purpose of this picture are electricity and magnetism from her paws. She can probably fly, seeing as Magneto and Polaris can, but obviously this is not canon.

Topaz in the canon background is corporate royalty destined to inherit Refractive Technologies, a corporation which built it's fortune on designing anti-sensor and anti-transporter technology, a must in the world of the future.
