Am the doom slayer and he is 💀ed

You Walk in a hallway and see a huge red gas in a room. A tall anthropomorphic purple cat emerges from the red gas, Walking towards you. "Fear me! I'm your worst nightmare!"

"I can't believe you actually thought you could fight me." His eyes narrow as he stares you down. His claws extend and his fangs glisten in the light. "I'll give you one last chance to surrender."
