Jassmint and Richard Nightluck had Selene just after they got married. Since she was born, she had this connection with water that wasn't very noticeable at first. She would always like to take her bath and would laugh while doing it.
While growing up, Selene was a bit of a wallflower at school and nobody seemed to care for her. She had a younger brother named Caleb that she developed to love when she took care of him, but he just saw her as his older sister.
As time flew by, Caleb developed his Pyrokinesis even before Selene knew about her own power. The X-Men found him at the young age of 10 and ripped him from his family to help him train. Selene was 13 by this time.
This was the time when her powers started to show. Due to the sadness of Caleb being away from her, she would turn a bit depressed and at school people wold think of her as a freak and looser. One time, when she was in 7th grade when the popular girls where trying to make Selene feel bad, a jock named Cameron from 8th grade told the girls to stop bothering her and so they did. Selene appreciated this and got to know Cameron better. She started to fall in love with him.
Then, another time, when Cameron got sick and didn't go to school. The same girls started to humiliate Selene in the bathroom and when she had enough, the water tubes exploded and everyone except Selene got wet. Somehow, she knew it had been her who did it.
Another time, when 15, she started to feel being stalked on the way home by a stranger. She then heard him run towards her and so she did. Then, she turned right into a dead-end alley. Within all, she was scared and didn't know what to do. However, when the man peeked into the alley, he didn't seem to notice Selene at all. Confused, she went out to poke the man in the face to see what was wrong, but then, she didn't see her arm. She got to run out of the alley and went home.
By this time, when the adrenaline had poured out, she was visible to herself and everyone else again. After this, she never saw Cameron again. They said that he was expelled, but when Selene went to
stalk visit him to his house. He wasn't there anymore and the house was open for sale. She turned exasperated as everyone that she seemed to love escaped from her life.
Finally when she turned 17, she duplicated herself one time while looking at herself in the mirror. She obviously got scared, but learnt that she could control the clone independently.
When Caleb turned 14, the X-Men sent him to a mission where he shortly died by not being powerful enough.
This angered an saddened Selene greatly and promised to herself that she would never be a part of the X-Men as long as it were her decision. Even if they swore to make her powers develop.
She finally got invited at a party when she was 17, almost 18, but only so the popular could pull a prank on her. At the end of the party, they soaked her in beer and alcohol. She got really mad and turned invisible. She then got a kitchen knife and from everything that she had inside, she killed each and everyone of the people who planned the prank. Which was more or less 15 students currently at the party.
Still invisible, she ran out of the party and went to a nearby river to clean herself and there, Quicksilver and Scarlet Witch found her and told her that they saw her abilities. They took her to the Brotherhood and she has been with them for a bit more than a year.
