Scarlet Blossom

Scarlet has been crazed for years and is still trying to prove that she's nice to this day. Under the Crazed, she became a villain, which started Project Diamond and her violence.

When Diamond Butterfly and Oliver talked, it was discovered that she actually came from another dimension, in which humanity had been wiped out, and her actual name is Blash.

Appearance
Scarlet, true to her name, has long, slightly wavy scarlet hair (though according to Oliver she can change it at will). Pastel blue eyes complement her pale Caucasian complexion. She commonly wears a white lab coat over a black shirt, gray pants, and black boots. Previously, she had light purple eyes, a sign of her being Crazed, a light gray shirt, light blue pants, and black boots. She also wears a mainly gold bracelet charm with light blue jewels that prevent her from being Crazed.

Personality
Calm: She never seems to get frustrated, always just heading to the next step if something goes wrong.

Perseverance: When she's determined, it's hard to throw her off the tracks.

Intelligent: She's smart, and not easy to fool.

Winston Blossom
Winston is Scarlet's son, with a currently unknown father. Their interactions, at the moment, is yet to be seen; however, Winston does seem to genuinely care for his mother.

Diamond Butterfly/Rose Almaz
Under the Corruption, Scarlet created Project Diamond, and managed to give Rose powers. Rose managed to escape, leaving Scarlet angry that her work had been wasted.

When Rose became a hero, Scarlet was her main enemy, kidnapping Diamond a couple times to continue the work. Every time, Diamond managed to escape, commonly with help. Diamond was constantly angry at Scarlet for changing her life forever, and so when Scarlet became un-Corrupted and came to town, Diamond immediately pounced. After hearing Golden was on her former enemy's side, she reluctantly stopped. However, Diamond is still very cold, and often rude, to the scientist. She didn't like interacting with her, ndandas more than one occasion pulled out a weapon on her, showing no regret for doing so at the time.

While Diamond seemed to be more respectful of Scarlet, even before talking with Oliver, and still after the recent events when Diamond discovered the truth, she was not wary of demanding answers from Scarlet when she believed the redhead had given Ally powers,

Oliver
Oliver and Scarlet's relationship hasn't been seen all that much - however, Oliver appears to hold high respect for Scarlet, or Blash.

Ally Anderson
The younger sister of the former leader and the scientist get on much better terms than Rose with Scarlet. They seem to be on very friendly terms, not exactly friends but acquaintances or allies (or ALLY'S ;D). She was also notably the one who sent Ally with a map to discover her old home and told the twin to bring Rose along.

Trivia
