Wonder Woman is the main protagonist of the show and is also the alter ego to Diana Prince. She is portrayed by Lynda Carter.
Wonder Woman's appearance changes slightly throughout the seasons. Most notably between Seasons 2 and 3. In Season 2, her hair is clearly a wig and is poofy and curly like. In Season 3, it's simply straight and long. Her costume only makes minor changes. She has a red and slightly gold coloured outfit with blue panties with white stars. She always wears a golden tiara but sometimes in the show, is seen using it as a boomerang.
Wonder Woman has many powers, and wears a magic belt, magic bracelets, and the Magic Lasso of Truth. While wearing them outside of Paradise Island, she is able to keep her Amazon strength. This gives her enough strength to lift grown men and move a plane. Anyone with the Lasso of Truth tied around them - including herself - is hypnotized into telling the truth. Her magic bracelets allow her to deflect bullets.
Wonder Woman may be much more powerful than Diana Prince, but isn't invulnerable. If her magic belt is removed or if her bracelets are bound by a man, she loses her Amazon strength. (In the DC Comics, Amazons who remove their bracelets go mad, including Wonder Woman herself.) Her lasso has shown to not work on one occasion when she tried to use it on Bryce. Wonder Woman can still be knocked unconscious by Chloroform, which has been used on her. Sleeping gas has also been used on her and it knocked her unconscious on episodes like Judgement From Outer Space Part 1, and The Murderous Missile where George knocked her in the face with gas and almost immediately she was knocked out.
Queen Hippolyta is Princess Diana's mother. She didn't want Diana leaving Paradise Island, but Diana put on a disguise and she proved she was the most powerful Amazon and her mother was forced to let her go.
Drusilla is Princess Diana's younger sister in Season 1, who becomes Wonder Girl. She visited Man's World twice as "Drusilla Prince," and even helped her sister fight crime while visiting.

Major Steve Trevor is Diana Prince's friend in Season 1. Even as Wonder Woman, she had a crush on Steve, but their relationship never became serious. (In the DC Comics on Earth 2, they did get married and had a daughter, Hippolyta "Lyta" Trevor, who became Fury.) While they never became a couple, there were many implications that she liked him and the same went for him. They never kissed and never usually got very close to each other with the exception of one moment in Judgement From Outer Space part 1 when the gas was still taking its toll on her and it appeared that she was going to collapse, but Steve held her hands and supported her on himself and while this was brief, it was a strong implication that they had strong feelings for each other.
Steve Trevor, Jr. is Diana Prince's friend in Seasons 2 and 3, but they never became a couple. (In the DC Comics on Earth 1, Diana and Steve eventually do get married.) His father, Steve Trevor, Sr. is deceased.
DC Comics had the Justice League of America on Earth 1, while Earth 2 had the Justice Society of America. Half of the members from both groups had counterparts, including Wonder Woman. In Season 1, Lynda Carter plays the Earth 2 version, while in Seasons 2 and 3, she plays the Earth 1 version.
