Jacqueline Beulah "Jackie" Burkhart is a fictional character and one of the two female leads on the Fox Network sitcom That '70s Show, portrayed by Mila Kunis.

Jackie is a self-centered, spoiled member of a wealthy family who can be rather insensitive to the needs and feelings of others, though is regarded by many as attractive and fashionable, about which she can be quite vain. She is one of the program's most conceited characters, and can behave quite selfishly. She looks down upon those of lower status in her school and has been said to treat them unfairly, and on the occasions she has treated them with respect she has not continued to do so for very long or only did it knowing that she could be rewarded for behaving in such a manner, such as when she ran for the title of "Snow Queen" but was utterly disappointed when she lost the election. For the most part, Jackie only cares about herself, and fashion is among one of the few other things that she is concerned about. She believes herself to be very beautiful and appealing, and has been involved in romantic relationships with Michael Kelso and Steven Hyde at different points in the series.

Steven James Hyde III, known as Hyde by his friends, is a fictional character from the Fox sitcom That '70s Show, portrayed by Danny Masterson. He is Eric Forman's (Topher Grace) best friend and by the end of season one, his de facto adopted brother. Hyde represents the rebel adolescent of the seventies that was suspicious of government and corporations.

Hyde was abandoned by his mother, Edna (Katey Sagal), who only appeared in three episodes, two of which featured only her screaming voice calling from inside Hyde's house. His stepfather, Bud (Robert Hays), had left some years earlier. A half brother was mentioned once in a Season 8 episode, though not much is known about him.

Hyde's best friend, and later foster-brother, is the nice, geeky Eric Forman. The two share probably the closest friendship out of the group, shown by how they care and rely on one another and one anothers' advice. When Hyde's mother left town at the end of the first season, Eric tried to persuade his parents to do something about his best friend's living conditions and thus Hyde was invited to live with the Formans, which Hyde does from season one until the series' end. He is adopted into the Forman family, and lives in the basement of their house. Since there are no extra bedrooms, he sleeps in a small storage room on a cot. When Red decided to kick Hyde out after an arrest for possession of drugs, Eric attempts to come to his rescue.
