As a former Ditzweld scientist marked for death by her own former allies, Tatjana is a very logical thinker. Rather than using magic like many people in the world, she mobilizes her technological abilities by having them all in battle. She strongly believes in scientific superiority and scorns the Deimos scum for their magic dependency, and she even did cruel experiments on some of the Deimos, including Camellia. She is somewhat reformed and rational now.

She can use Sigma Storm to bring upon a barrage of light attacks onto her enemies, or the Sign of Silence or Hypnotize to status out her opponents, or even heal her wounds using Medical Machine. Her diverse skillset and the powerful Sigma Storm allow her to be competitive in Heavy, where she took a win before retiring to her studies.
