This is a list of characters appearing in the series That '70s
Show.Portrayed by Topher Grace: The protagonist; Eric is a nice guy,
generally geeky, physically slight, and somewhat clumsy. He is a
smart-aleck with a fast wit and a deadpan sense of humor. He convinces
his parents to let his best friend Steven Hyde move in with them,
making Hyde like a brother. His father, Red, is always hard on him (as
a way to toughen him to be a man). Eric is in a relationship with his
longtime love and neighbor Donna Pinciotti. He decides to become a
teacher after high school, and he leaves the series at the end of the
seventh season to teach in Africa, and returns for the series finale,
reuniting with Donna.Portrayed by Laura Prepon: Eric's longtime
girlfriend (and briefly fiancée). Donna is intelligent, good-looking,
and a feminist tomboy. Although she does not agree with what Jackie
represents in the beginning of the series, they become friends. Donna
is in a relationship with Eric for seven seasons (despite their
break-up during season 4). She has brief romances with Casey,
Michael's brother, and with Randy during the final season and quickly
ends it. She rekindles her relationship with Eric at the end of the
show's finale.Portrayed by Danny Masterson: Eric's best friend and the
anti-establishment member of the group. By the end of season one,
Kitty Forman prevails on her husband to allow Hyde to move in after he
was abandoned by his mother (played by Katey Sagal) and living in
squalor. Hyde has a witty, blunt, and sarcastic sense of humor, and a
rebellious personality. He is also smart and realistic, and the other
group members often ask for his advice. Although Hyde dates Jackie for
three seasons, they eventually part and in the final season he marries
an exotic dancer/stripper named Samantha, who, unknown to Hyde was
still wed to her first husband (Sam McMurray) when she married him. As
Donna points out in "My Fairy King", that means Hyde and Samantha are
not legally married. In the seventh season, Hyde meets his biological
father (William Barnett, played by Tim Reid), a wealthy African
American businessman. Hyde also has a straight-laced half-sister name
Angie from this newfound relationship. Barnett, who owns a chain of
record stores, makes Hyde first the manager, and later the owner, of
the Point Place store called Grooves. List of That '70s Show characters Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
