Of course! Why didn't I think of this before???
Okay, after about an hour of trying (and failing) to decide on a power, I figured I should reuse one of my old characters that never got to see action. She's pretty interesting and I think her power suits this roleplay. So let's get down to it.

Name: Charity Russel

Age: 16

Alias: Red

Subject Number: 9

Appearance: She has no visible changes, except for the fact that one of her eyes is light blue.

Personality: Her personality depends on her powers; normally she's a quiet but determined girl, set on getting her way, but when her power activates, she's terrifying. Violent, impulsive, and overly confident, she's the exact opposite of her regular self.

Power('s): (I'll have to explain part of her history here, sorry) Her twin brother was taken to the facility as well. They gave him massive amounts of power, so much that it couldn't be contained in his body. To solve this, the scientists combined him with his sister to balance it out. It's fairly difficult to control, but Cherry can bring her brother's power and personality to the surface, allowing her to create blasts of excess energy, along with gaining superhuman strength. It tires her out quickly, though, and she passes out after using it for more than five minutes. It also changes her gender on a cellular level; her face looks the same, her body does not.

Equipment: One of those zinc energy bracelets that can calm her down to deactivate her power. Also, a baggy long-sleeved t-shirt with an odd collar and baggy shorts.

History: Just that her twin brother was brought to the facility with her and then was powered up and combined with her. I might elaborate more in-thread.

Goal: To find out who's in her that makes her feel so heartsick.

Other: That picture is adorable. I don't care what anyone says.
