Sigma

SIgma is a character from the Iczer Series and is a major antagonist around the end of Knights of the Multiverse Season 1. She was created by Dr. Neos of the League of Scientific Renegades to help them conquer the world and destroy her treacherous "sister", Atros. However, unlike her sister, she is armed with a Getter Ray power core.

In Season 3, she was recreated using Black Lady's magic and some remains of Unicronian technology to battle the Knights once more as a part of the Guild of the Multiverse.

Personality
All Sigma cares about is her drive to fight and kill. She values power above all else, and thus is extremely cruel and arrogant. She has no respect for the weak, or anyone of lower status, including some of her teammates and the scientists that created her, whom she ruthlessly destroys when they fail a mission on account of being "soft." For the most part, Sigma tries to remain calm and somber even when things seem to get drastic, but she does still have a bit of a temper when favor is not on her side, and like her sister, tends to get annoyed when somebody interrupts her battles, often blasting right through them on the spot, no matter who it is.

Animated Short #4
Around the end of the short, Sigma appears with Blade and Orgun by her side. As the Crystal Knights gather around to take the three on, Sigma snaps her fingers, triggering Gigantis's awakening. Upon the giant breaking free, the trio ascended into the air to let Gigantis do its work.

Powers & Equipment
As she is based off of Atros's abilities, Sigma thusly has all of Atros's powers, but are significantly more powerful thanks to her Getter Ray Core: Sigma is able to fly at incredible speeds, nearly reaching the speed of light, appearing as a streak of green light. Sigma is armed with two beam sabers based off of those used by the Gundams, both emitting a strong, green laser powered by Getter Rays. They're surprisingly strong too, able to hold back the Zeta Gundam's beam saber and slice through most metals with ease. Sigma can fire Getter Beams from her fists. She can also fire smaller, weaker beams from her fingertips. Sigma is able to charge up her energy in a green aura and charges into her opponent at high speeds.
