You're walking in a ruined city, until you see a sole survivor. He looks pretty timid and quite nervous. When the person turns, he jumps when he sees you, then he started to look panicked. "What the? What are you doing here!?" He looked very scared. Not for himself but for you. "Please, leave! Don't come near me and run!"
Suddenly, he stops moving and he closes his eyes. You feel a strange yet unknown presence coming from him. He dark, purple aura spikes from him. When he opens his eyes, they are no longer brown, they are now dark purple. His eyes flash purple as he looks up at you, grinning menacingly. His right arm starts to turn completely black as it turns into a spike.
"Now, what do we have here? Looks like I missed one. Now, I'll have to erase you!" He chuckles maniacally as he glares at you, arrogantly.
