Frieza

Personality
being evil and cruel and having no allies viewing all around him as inferior even his own son Kuriza and hating the fact that anyone could be stronger than himself and killing them the chance they pose that opportunity too as seen with king vegeta and his family and only keeping his family alive due to respect towards his father and knowledge he has of their race and knowledge of the universe he has. Frieza has a regal demeanor and a dark sense of humor shown with how he kills his allies and enemies and he has a perfectionist point of view such as hoe he kiils killing men who dont meet his perfectionist view of his army and being rather smart but having ego and a superiority complex  which often limits his intelligence from being greater.
