Dark Star Chaos

Story
Growing up in a rural background, Maria always fantasized about herself becoming a great wrestling champion. But not long after starting her formal training, she realizes that she is not actually that talented in wrestling even compared to her local peers. However, she believes she can compensate with extra effort, and thus trains harder and harder, yet still is unable to break through the ceiling of mediocrity. One day, she picks up a mask and puts it on, which makes her feel like she has become a new person. Suddenly, her wrestling skills explode and she is able to crush every opponent she faces with almost supernatural power, which she credits to her mask transforming her into the wrestler she dreamed of being. She joins WWCA as Dark Star Chaos, with no one knowing her original identity or what she looks like unmasked. From here she quickly becomes the WWCA ace and famous across America as an enigmatic and seemingly unbeatable contender.

When Chaos learns that IWWF World Heavyweight Champion title has fallen into the hands of Beauty Ichigaya of New Japan Women's Pro-Wrestling, she challenges Ichigaya for the title and crushes her as easily as she has crushed any of her previous opponents.

So when Mighty Yukiko challenges her for title, Chaos expects another easy win for herself. But there is something different about Yukiko compared to any other opponent she has faced, so that Chaos ends up losing a match for the first time since she put on her mask, and her brief reign as IWWF World Heavyweight Champion is over.

Later, she and The USA are one of the tag teams invited to the "Strongest Tag League" battle.

Personality
Chaos' mask gives her toughness in defense and strength in offense beyond human capacity. Her Dark Star Hammer literally sends opponents flying.

She keeps her mask on even when not wrestling. She has been seen wearing her mask with casual clothes outdoors.
