Vegeta is a well-built man of below-average stature with light tan skin, standing at 164 centimeters tall. His hair is black and spikes upwards with a prominent widow's peak. Like most Saiyans, he possesses defined, black eyes with a consistently stern look to them. Like other Universe 7 Saiyans, he was born with a prehensile, brown-furred tail, until it was permanently cut off by Yajirobe. Over the course of the series, Vegeta's physical appearance changes. While originally appearing very short and lean, especially compared to his massive partner, Nappa, he later seems to be somewhat taller and noticeably more muscular. His hair becomes shorter and his forehead becomes smaller and his facial features, which are perpetually in a scowl (in contrast to before he lost his first fight with Goku, when he smiled most of the time), also look more distinct and sharply defined as the series progresses, making him look much older in later sagas compared to what he looked like in his debut. A major characteristic of Vegeta's is the fact that he is one of the only Saiyans who have continued to don the traditional Saiyan armor, in both combat and regular life. This armor became more and more minimalistic over the years, mirroring Vegeta's development from a cold-blooded conqueror to a defender of Earth. During most of Vegeta's adult life working under the Frieza Force, as well as his appearance in the Saiyan Saga, he wore white armor with yellow plates that has thin black lines over the stomach and lower back, plus rounded shoulder, hip, and crotch guards, that also possessed yellow plates with thin black lines. Underneath his armor, he also wore a blue jumpsuit, white gloves, and white boots. He would often wrap his tail around his armor in a belt-like fashion, and usually wore a red scouter (green in the manga) over his left eye. Vegeta is arrogant throughout the series and becomes bitter due to the abuse his race suffered at the hands of Frieza, as well as his injured pride due to repeatedly falling short compared to another Saiyan. Following the destruction of his homeworld Planet Vegeta, his hatred toward Frieza grows. His royalty seems to have bestowed upon him an inflated sense of superiority, holding himself above nearly everyone he encounters. Regal, egotistical, and full of pride, Vegeta was once a ruthless, cold-blooded warrior and outright killer.

Johnny's best friend, 20, and a powerful warrior in his own right. Evan fought alongside Johnny against Yamcha years ago and has been a core member of the group ever since. He is perhaps slightly more hot-headed or tactical than Johnny, often serving as the strategist during their duo fights. He wears a grey t-shirt with a black necklace connected to a blue crystal fragment, he wears glasses which covers his eyes most of the time, he has dirty blonde slightly curly hair, braces, grey and black camo shorts, and brown boots with a grey zipper connected to it. His loyalty to Goku and the rest of the Z Fighters is absolute.

The Saiyan raised on Earth, currently at the peak of his power (though not yet a Super Saiyan). He wears his orange and blue Gi with the King Kai symbol on the back. He is observing the battle with a serious expression, analyzing Johnny and Evan's techniques. He views them as lifelong friends and trusted allies. He is ready to enter the fray at a moment's notice.

The galactic tyrant responsible for the destruction of the Saiyan race. He is currently in his final form—a sleek, white, bipedal alien with a purple bio-gem on his head, a purple tail, and black lips. He is sadistic, arrogant, and amused by the resistance of the "insects" opposing him. He floats effortlessly above the ground, radiating a terrifying purple aura of ki.

A former bandit turned Z Fighter. He appears in flashbacks to the "Desert Smackdown" where he first met Johnny and Evan. He is currently on Earth (or deceased/preparing for the arrival of the Saiyans in the flashback timeline), but his memory serves as the anchor for the group's friendship.
