Every time he tries to use it, he gets better and better overtime. Then, Yamai showed Jack; Chaos energy manipulation. Jack was so surprised by this, he really wanted to learn about that. Yamai starts to fight Jack with her chaos energy. Jack was struggling to keep up with his older sister but something happened to him, the chaos energy began to form around him like a suit of armor. Surprised by this, Jack wanted to see if he could control it. So, Jack tries to use the chaos energy to flow to his fists when something happens, the energy emanating from Jack starts to collapse and makes Jack fall to his knees. Yamai tells Jack that “Chaos energy requires focus of self”, Jack began meditating for 3 months. After the 3 month meditation, Jack started to do the same thing. This time, it worked and he wanted to fight his sister again. It was a close battle when they fought, but Jack won, just barely. Yamai was proud of her little brother for using chaos energy and applying it into combat. When Yamai showed him the 7 CHAOS EMERALDS She wanted to see if Jack was ready. So Jack got started to charge his chaos energy. The emeralds began to float and circle him. As the transformation finished, Jack's body was a different color. Instead of the normal color being yellow, it was a green,emerald-like color and his stripes were yellow. This means that the transformation worked but for only 2 minutes. Jack starts to train for 5 years trying to figure out how to use his newfound power for Good. When Jack was 17, he wanted to keep training but, when he went to ask Yamai, she left to go on her own journey. He was a little sad but he knew he couldn't rely on his sister too much. So, Jack starts his journey to see the world and make friends on the way, and he will be ready to fight for what he believes is right.
