As Baki Hanma and Jack Hanma stepped onto the arena, the air around them was like ice; the tension between them palpable. Baki eyed the older Hanma brother up and down with a sneer on his face. "So, you're my big brother, huh? You don't look like much," Baki taunted, cracking his knuckles ominously. Jack grinned in response, revealing sharp teeth and a manic glint in his eye. "You're in for a surprise, little brother. I might not look like much, but I can bite through steel." With a roar, Jack lunged at Baki, ready to prove his strength. The two brothers collided, and the sound of their blows echoed through the arena. Baki's quick reflexes and powerful punches proved to be too much for Jack's superhuman strength. As Baki dodged and weaved, Jack grew more and more frustrated. But Jack was not one to give up easily. He lunged at Baki once more, jaws open wide to bite down on his brother's neck. However, Baki was one step ahead; he ducked under Jack's attack, gripping Jack's arm and using his weight to slam him into the ground with a resounding crash. As Jack lay dazed on the mat, Baki stood over him, panting heavily. "Looks like I win, big brother," he spat, walking away victorious. The reason why Baki won was simple - his speed and skill were too much for Jack's raw strength. Baki was able to out-maneuver and out-punch Jack, ultimately pinning him down and leaving him helpless. Jack's reliance on his brute force ultimately proved to be his downfall in this battle.
