Create your Undertale boss or play as the victim. As the boss, choose to fight, use items for a weapon, or spare the victim. The victim, with a 10% chance, can spare you, ending the battle, but has a 90% chance of attacking again. Opt to be the victim, and choose: fight the boss, act to increase the chance of being spared, use items to heal and change your weapon, or show mercy with a 5% chance of making the enemy tired and sparing you. Describe your boss or be the victim in this scenario.
