Since Quinn had received a boost in his celestial points, he had only used his powers recently. When sending out a beacon of his energy, using the strange device on top of Green City. However, he had yet to see it in action, actually using it in an attack.
Before, Quinn could only use the Celestial energy as it powered the blood in his body. Allowing him to fight hand to hand with the celestial energy, but recently, when fighting against Russ, he had discovered a way to use it externally by powering himself, cutting his body, and using blood control to control his very own blood.
This was precisely what Quinn was doing now, controlling the blood. Using this tactic did drain Quinn of blood, which meant he was losing health, but after seeing how recklessly he was attacked just then, he was a little annoyed in a neighbourhood full of those who had done nothing wrong.
