As the battle between Undyne and Stone Man was about to commence, the atmosphere around them changed. They both knew this wasn't going to be an ordinary fight, it was going to be wild. Undyne glared at Stone Man, determined to defeat him. "Prepare yourself Stone Man, you're about to face the power of a hero!" Stone Man chuckled, "I admire your determination, but you don't stand a chance against me, a robot made of stones." Undyne quickly took advantage of her speed, charging at Stone Man with her magical Spears. Stone Man tried to dodge but in vain, one of the Spears pierced his Brick Armour, causing him to stumble back. However, Stone Man wasn't going to back down easily. He rose back up, powering up his Power Stone skill. The three stones launched at high speed towards Undyne, creating a circular pattern. Undyne gritted her teeth, trying to dodge the stones but couldn't. As the stones hit her, she was knocked back, her guard and HP dropping drastically. Stone Man laughed triumphantly, "It's time for you to accept your defeat, hero!" But Undyne wasn't about to give up. She stood up, her determination growing stronger as she realized Stone Man was evil. With a fierce look in her eyes, she charged again at full speed, unleashing her magical Spears. Stone Man tried to push her back with his Power Stone, but Undyne was too quick, dodging the stones with ease. She lunged forward, piercing Stone Man's Brick Armour multiple times, leaving him vulnerable. In a final blow, Undyne used all her might to pierce Stone Man with her magical spear, causing him to disassemble. As he was disassembled, Undyne took a breather, thinking the fight was over. But her relief was short-lived. She quickly realized Stone Man was invincible while disassembled. She braced herself, ready for another attack. As Stone Man reassembled, he fell to the ground, defeated. Undyne stood over him, victorious. "I told you, Stone Man, I'm a hero and even in death, I fought with everything I had!" Stone Man coughed up oil, "You may have won this time, hero, but don't get too confident. I'll be back, and I'll be stronger." Undyne smiled and walked away, knowing that no matter what challenges she faced, she would always come out on top.
