Okay, here we go! SU, awaaaay! Let me know if I need to change anything!
Name: Quantum (She has no 'street name', due to her powers. See below for more info.)
Age: Unknown, even by herself. You could guess she's around her mid-twenties though.
Appearance: Quantum is made up of pure, purple-pink energy, but is still in the form of a human woman around her mid-twenties. Somehow, whenever she speaks, her voice seems to have a vibrant tone, but it has no real impact on her speech patterns, or how audible she is. Despite being made up of energy, she still has a defined human form, hands, fingers, feet, and even a concentration of energy in certain places such as her eyes, nose and mouth. She claims the form comes naturally to her, though supposedly she'd be able to simply form into whatever she'd want due to being made out of energy. But for reasons specified later, she both doesn't, and can't.
Attire: Due to being made up entirely of energy, Quantum is unable to take –proper- human form, with skin and all. She's forced to wear a 'skin'-tight rubber/latex suit to prevent her energy-form to violently expand and… well, blow up herself and everything around her. When she's at home and relaxing, she'll only be wearing the 'Inner Suit', as it's been dubbed, which is as close to looking normal as she'll ever get.
Her 'Outer Suit' is an armored, technological wonder, which she's able to enter to protect the much more fragile Inner Suit from tearing. It's made up of a strange, almost alien metal, which is extremely resistant to attacks and will only rarely break apart. It's a sleek black and silver look with purple neon-like lights, which is her own energy powering the suit.
On her palms and under her feet are a specific set of a circle within a ring, which she's able to concentrate her energy into, in order to shoot out beams or blasts of energy, which will scorch and blast away whatever she targets. The Outer Suit also augments her already fairly formidable strength, making her able to punch through solid concrete and lift extremely heavy objects.
Personality: Quantum is eager to prove herself to others, knowing that she has nowhere else in the world where she could fit in, she tries to make every single thing she does in regards to crime-fighting count. However, exactly because she could not fit in anywhere else, she's also very worried of failing, which makes her very uncertain, awkward or even outright shy around other super-powered people.
On her own though, she's eager and headstrong, willing to jump into dangerous situations in order to protect and defend. To her, life is precious, and a normal life is something that she knows she could never have, which is why she strives to protect those who don't know how lucky they are.
Powers/abilities/weapons/etc: Being made of pure energy has both its perks and downsides. On one hand, she's able to fly and shoot beams and blasts of energy from various parts of her suits, as well as having increased strength, which is further augmented by her suit. Said suit and due to her being made of energy, she's also able to take quite a few hits. She still feels pain, which is a mystery as to why, even for her, but she can take quite a few hits before going down.
On the other hand, if her inner suit starts rupturing, she needs to concentrate deeply in order to control the energy that's making up her form. If the tears become to large or too many, or she loses concentration, her energy will unleash itself, violently expanding and exploding, taking both Quantum and a larger chunk of wherever she is with her.
Strengths:
• She's headstrong, willing to charge into dangerous situations to save her allies, or innocents.
• Being made of pure energy makes her more durable (at least in her Outer Suit), and also negates the need for eating, bathroom breaks, etc.
Weaknesses:
• Due to her at times rash decision-making, she occasionally ends up in sticky situations, where she needs help to get out of.
• Despite not having a need to eat or go to the bathroom, she still finds that she needs at least as much sleep as a normal person.
• Since she's made of energy, her body is –incredibly- unstable. If her Inner Suit starts rupturing, she has to retreat quickly in order to get it fixed and not destroy herself and those around her.
Origin Story (history): Quantum has no memory of who or even –what- she is, prior to being found by her friend, Doctor Mengsk. According to him, he found her out in a field in the Outlands in a weird, alien-like metallic pod. A being of pure energy in the shape of a woman. He managed to bring the pod back to his lab in Mount Cedar.
When she woke up, she was panicked. She had no idea who or where she was or how she'd gotten there. After calming her down, the doctor managed to convince her that he was a friend, and set to work on creating a suit that would allow her to exit the pod without hurting anyone.
Once they had managed to put her in the suit and she exited the pod, the two started trying to figure out just exactly who and what she was. She had no memories of her past or even her name, but she did know basic things like language, being polite, everything that makes us human. Due to her not knowing her own name, the doctor decided to suggest one befitting of her less-than-normal nature, which she adored; Quantum.
As time went on, they began doing tests, figuring out that she was able to fly, emit laser-like blasts and beams of energy, which made Mengsk alter her suit to have a couple of special, thinner patches of the material around her palms, feet and chest, which would allow her to emit these energies, without destroying the suit.
After a couple accidents where her Inner Suit was slightly torn, and a good deal of damage was sustained on the underground lab, the doctor created the Outer Suit from the remains of her pod, which allowed her to move about without fear of her Inner Suit tearing.
For about a year now, she's been living in the lab, unable to go outside, of fear of the government trying to capture her, believing her an alien, or something worse. She tried to help the doctor, but she wasn't very tech-minded, other than working with a computer, which she picked up a bit on, so she stuck to mostly carrying around things for him and doing heavy lifting, while still performing some tests for him.
Now, however, somehow the Champions managed to send a message to Mengsk's computer, asking for Quantum's assistance with something. It took a lot of convincing from Quantum's side, but she managed to talk Mengsk into letting her go and try to help out. Hopefully, she could live up to the expectations of one of the Heroes of Hyperia.
