While many people in this dimension mistake Tessa for a witch, she is actually something even more powerful: a sorcerologist. That is, she employs magic in her everyday studies to discern the properties of the universe. She is as intelligent as she is powerful, and she is constantly on a quest to acquire more knowledge and understanding about the nature of all things. Unfortunately for her, she often finds that in order to gain information from those that she meets, she must typically beat it out of them, but she doesn't mind as she enjoys a good fight, and can employ several of her unique skills on her opponents. As illustrated in her Transformation Combo, she can alter her nature to something more savage and beast-like. In her Arabian Combo, she can tap into the mystical Arabian arts of snake taming and genies in a bottle. Her Circus Combo shows her ability to entertain a crowd by summoning an attack-dolphin from her top hat, and transforming her poor kitty into a rocket which she straps unsuspecting opponents on to before it blasts off. In her Robo Combo, she shrinks down in size and is replaced by a large robotic construct of herself which conducts the fighting for her.
Tessa is seeking out a staff which has magical shapeshifting properties, and she imagines Hsien-Ko knows of its whereabouts.
If you manage to win two rounds perfectly, back to back, a very startled and bedazzled Mai Ling will appear from behind Tessa's back.
