Inspired from an artwork of Rapunzel which was writting "I BATTLE FOR THE SUN" on it. And since Deyna is powerful, she can of course get to that point of using her powers (with the difference that her hair are not 70 feet long like Rapunzel's xD but I just wanna try playing out with the movements of the hair) although it is quite exhausting in the end (when she is done using her strongest attacks) and might collapse and take some time to recover. Her power is the energy manipulation also.
