I wanted to make a Champion that could control gravity this is what i came up with this.

Louis : The Gravity Kid

When Louis was born he was as ordinary as any human child and his brother Lucas always bullied him. As he grew older his lust for adventure made him late for schools and would always end up going home late. During one of his adventures he discovered this under ground facility which created machine and weapons. His curiosity led him to explore even deeper until he was caught by some guards. He ran as fast as he could and hid in one of the rooms. Inside he found this purple necklace floating in mid-air. As the guards were pounding on the door Louis quickly took the necklace hoping it would give him a chance to escape. With one swing of his hand the door flew open and knocked out the guards. He manages to escape. When he returns he showed Lucas his new power, Lucas became jealous and ran away. Louis continued his adventures while he practiced his gravity powers. After he returns from an adventure, he could see his village engulfed in black flames. He ran to the village to see his brother burning away their parents with his black flames. Before Louis could attack him he vanished into his flames. Louis vowed to kill him. As he traveled the world he was attack by countless people who had mistaken him as his brother. He was told that his brother joined the league of legends. He decides to join the league and kill his brother. He now fights in the league hoping to find his brother and end him.
