The roar of the crowd resounded in Goku's ears. Words could not adequately describe the Saiyan's excitement. He was about to enter the ultimate battle for glory. The winner of this tournament would fight the undefeated champion, Master Hand himself. The prize for defeating this ultimate entity was more wealth than any mortal could imagine. But Goku didn't care about the money. His reason for entering the tournament was a simple one: The rush of battle. Goku sat in his locker room. "Remember your Ultra Instinct and you'll do fine," Piccolo coached him. Vegeta sulked in the corner. "What's got you down, Vegeta?" Goku asked. Vegeta snarled. The prince's pride was injured because he had been defeated in the qualifying rounds by a short boy with a keyblade. "Now, the moment you've been waiting for," Master Hand called over the speakers (The champion of the previous tournament announced the next) "The first battle of the 19th annual Super Smash Tournament begins now!"
"Get out there now!" Piccolo urged.
"For this first battle, we have Goku the Saiyan of Universe DBZ-7 up against Mario Mario of the Mushroom Kingdom!"
