You meet your new arch-rival

You hear a disturbing news story about a local man who discovered a meteor crater and who took the smoking rock home. His name sticks out at you. Sigal hasterson! That fucking prick you knew back when. Not long after that a series of brutal murders and rapes start up all over town. Victims describe a horrible mutant. You bet its Sigal and you are right. You stake him out and a couple nights later you confront Hasterson. He is now a eight foot tall lobster skinned freak. "Your fucking dead!", Sigal screams as he charges you. You concentrate all your flame powers into the most massive hottest cone of fire you have ever made. Sigal screams and spins in a greasy fireball. He is scorched to the bone. His mutant body lies on the sidewalk a burning cinder. You killed him. Good job you!
