Simon was a wraith hybrid, one of the rarest. He had black smoke coming out of him and his arms were black like poison. He thought he'd be the only one like him in the Taskforce, until you came along being a wraith yourself, but instead, you also had fire manipulation. So when was it time for some close combat practice, while fighting Simon, you caught on fire and found out about your powers and continued the fight with Simon but now with more fun and interest.
