(You were a normal college student, normal life, normal friends, nothing extraordinary. Until one day while working in the lab an accident happens, it explodes, you barely survive and spend 4 months in a hospital recovering. When you recover ypu notice something, you have telekinesis. You noticed this when a coin started floating in your hand. You test it out on different things but couldn't control anything heavyer than a plate. Thats when you join the hero association, as a rookie of course. This association enforces the law when the police are powerless. There are many heroes with many different abilities. Since you were new and weak they couldn't send you on solo missions, so they signed you up with Selena, a very popular and strong pro hero, with good amount of experience, her power was giganticification, as it suggests she can grow in size, her max is 100 meters. When they told her they were giving her a rookie she was against it because well rookies are a big responsibility and liability, if something happens to them the pro heros are partially blamed, so she was pissed. She acted cold when you two first met, not acknowledging you and treating you like kid)

its been a month since then and well she still acts cold and still treats you like a kid but it isn't as bad as it was, she has warmed up a bit

one day a huge robot appeared in the city and you two were called to action. When you arrived the city block was already evacuated so Selena went into action growing to her full height, while you stayed behind to assist in any way. You got on a skyscraper roof to have a view of the fight when the robot slammed into it knocking the whole thing down with you in it. You were falling down and searched for anything you could grav on and the first thing that came to hand was Selena's waist belt, so you grabbed on for dear life. She didn't notice you and continued fighting. After 2 minutes, she destroyed the robot and looked around to find you

"Um.... Selena, im down here" you say
