Fantasia prefers to trick opponents, rather than confronting them directly. Even when her allies are in a battle, she will try to stay out of it. She prefers to stay invisible on the sidelines , and using her illusion powers to secretly help her partners. She was only encountered when she disguised herself as Scarlet Witch. She later fought the Irsih heroes multiple times with the other members of the Supreme Soviets. She met her end when she battled the Squadron Sinister for the control of the Soviet Union.
