As Caesar had his gaze fixed on the masked vigilante assailing a nearby building, he did not see a blast of pure fire approach him until it was too late. Caesar was hit and was engulfed by the flames. Caesar was screaming in pain, parts of his flesh melting in the inferno. Despite the pain, Caesar had to act quickly or, in a matter of seconds, be roasted to the point were he couldn't move. Immediately he proceeded to stop, drop, and roll while using his signature Ice Breath to extinguish the flames. The flames were quickly removed, but the damage was done. He was scorched to the point that trying to transform and fly was far too risky. Had he been in dragon form, his scales, while they would have partially melted from the attack, would cushion him from the intense heat. But since he was in human form he had no such protection, exposed to the full blast of pure hell. 

Knowing the shot came from below and being unable to fly, his options of retreat were limited. If he took the stairs or elevator down the building, his assailant would certainly be waiting for him and be ready to attack again. Being left with little other choice and barely able to stand, he decided to call for help from the Brooding hero.
