On the Neutral Route before the fight begins, Asgore destroys the MERCY button while on the Genocide Route, the MERCY button is already absent. He attacks mainly with fireballs and his trident. Asgore forces the protagonist to fight him, and the protagonist cannot spare Asgore. The protagonist's HP can never drop below one on any given turn; this gives them a chance to heal every time that they reach 1 HP. After dealing the final blow to Asgore, the protagonist can choose to either "FIGHT" or give him "MERCY"; the "MERCY" button has cracks in it from being shattered.
