abilities:

• Selena turns into Super Nova when she undergoes intense stimulation and excitement. any for will do, whether it be from anger, intense physical activity, nervousness or stress, fear and panic, or even as simple has extreme happiness. any form of extreme excitement can trigger a transformation.
• when she is super nova, she is incredibly strong. her strength and durability increases ten fold. her senses become heightened, and so do her reflexes. she also gains the ability to generate and release vast amounts of energy, which she can use to fight.
• however, super nova is her own conciseness. selena is no in control when she changes into super nova. super nova's evil personality if the result of abuse from when selena was young, combined with enhancing effects from her mutation. weakness:
• super nova calling herself a god is no understatement. due to her abilities, and the fact the she can also heal herself when needed, make her almost impossible to take down by normal means. if she was facing someone of equal or greater power then herself, then she could be taking down normally. however, when facing someone of lower strength of her, she has a clear advantage. the best bet would either be to find a way to subdue her, or draw out the fight long enough for the transformation to wear off, and for her to revert back to selena. Selena: Likes: -calm environments, peaceful interactions, close friends, studying and learning, hard work and nice people. Dislikes: -aggression, anger, people asserting dominance, loss of control or a situation, super nova, and people finding out about her other half. Super Nova: Likes: -conquest, power, rage, fighting, putting "weak mortals" in their place, torturing people and selena, worthless attempts to take her down, and death. lots and lots of death. Dislikes: -anything dealing with selena, peace, or anything else not relating to her dominating as many people as she can.

Super Nova:
-Malevolent, Evil, Heartless, crule, thoughtless, twisted, mental, angry, and Chaotic
Due to being abused when she was young, selena developed a violent and twisted personality that was fueled by rage. due to this and her issues at home, she was desperately in need of money when she headed to college. she found a company offering high pay for people willing to test experimental treatments for a variety of different ailments. considering it a win win, she applied. the company though was actually a subdivision of a secret organization. seeing selena had an alternate personality, they found potential in her and used a "secret wonder drug" to give her a mutation. however, during this process, an accident happened, dousing selena in a mystery concoction that enhanced her mutation even further. she quickly transformed in to super nova, and proceed to rampage.
after these events, selena focused on doing what she could to contain her new and more powerful alternate self. in her free time, she looks for ways to cure herself of her situation. though every now and then she can't stop super nova from showing her face, and it leads to interesting predicaments....
