As the fierce battle between Baki Hanma and Jack Hammer began, the atmosphere was tense. The two opponents glared at each other, waiting for the right moment to strike. Suddenly, Baki darted towards Jack, using his Demon Back technique to increase his strength and speed. However, Jack was not intimidated. With the help of his Steroids ability, he grew to a towering height of 10'2 and countered Baki's attack with his own monstrous strength, causing them to collide fiercely. The clash of their brute force produced a deafening sound that echoed throughout the arena. The judges and audience trembled in fear at the display of power. The two fighters refused to back down, as they continued to exchange blows with equal force. It seemed like the fight could go on forever, until Baki unleashed his ultimate technique: the Demon Brain. As his brain function increased by 50%, Baki's movements became too fast for Jack to keep up. He dove towards Jack, grabbing him and grappling him with all his might. But Jack wasn't going down so easily. He used his Ground Skip ability to throw Baki off balance, and then applied his Demon Bite technique, which almost rivaled that of the legendary fighter Pickles. Despite the intense pain, Baki refused to give up. In a moment of clarity, he thought of his girlfriend Kozue, who was cheering him on from the sidelines. Her loving inspiration gave him the strength to break free from Jack's hold and make one last effort to win the battle. With his Grapple Enemy ability, Baki unleashed all his remaining strength in one last attack, overpowering Jack and knocking him out. And so, the winner of the fierce battle between Baki Hanma and Jack Hammer was Baki. His impressive display of strength, speed, and determination was unmatched, and it was clear that he had come out on top. As the audience cheered and the judges declared his victory, Baki couldn't help but feel proud to represent his family name and continue his father Yujiro Hanma's legacy.
