Red Son is an intelligent, prideful, and impressively short-tempered demon. He is a mad scientist of sorts, creating a multitude of weapons. He has a flair for the dramatic and makes a show out of the majority of his actions. Befitting his maniacal personality, he is prone to outbursts of rage when things do not go his way, or when he finds himself challenged by those he deems "inferior", which is most people. He often belittles them and insults his opponents, yet he gets flustered very easily.
