Vega

Vega is a selfish character who has been unable to overcome his severe childhood trauma. His beautiful mother was killed by an ugly stepfather, as a result of which the baby began to perceive people very subjectively, based on purely personal feelings of "beauty" or "ugliness."

Because of his narcissism, Vega has a hard time making contact with other people. He tends to make fun of his rivals. On the other hand, Vega is well mannered and has respect for women. He is attracted by the beauty and strength of young female fighters such as Chun-Li and Cammy;  in the case of the former, he often compliments her appearance.

Vega loves to wear a mask. He does this to protect his face from injuries during battles and even sunlight. This character sometimes takes off his mask after winning fights. Megalomania is also present in him because there are many giant Vega's portraits in his house.

This character can also be called a sadist.

Perhaps all these negative character traits he acquired due to violence in his family when he was a child.
