Yuccana is one of the last of her species, a very durable, and power laden race they were nevertheless destroyed with their race, some say murdered by one of their long time adversarial species in their quadrant.
Yuccana, had basically worked as a mercenary for hire, and merely wants to see the universe burn one planet at a time after the loss of everything. She especially likes the role of superhero killer. And has focused much of her time towards heroes on Earth.
I meant to say their planetary system was destroyed.
