Marcie is a bespectacled fictional character featured in Charles M. Schulz's comic strip Peanuts. She serves as comedic foil and best friend to tomboy Peppermint Patty, plays a supporting role in some of Snoopy's heroic fantasies, and displays a romantic interest in Charlie Brown. She has dark brown chin-length hair and she usually wears a t-shirt and shorts, like Peppermint Patty. She and Peppermint Patty were the only girls in the strip to wear a t-shirt and shorts (although the girls wore pants during the winter in the strip).
Forever known for her unassuming sweetness and intellect, was officially introduced into the cast of Charles M. Schulz's Peanuts comic strip on July 20, 1971 (although a look-alike character named "Clara" appeared in the strip with her friend Sophie as early as 1968). In the TV special, You're in the Super Bowl, Charlie Brown, Marcie is given the last name Johnson, although this was never used in the strip, so can not be canon. As for her family, in one strip Marcie states that her mother is designing a freeway, indicating that her mother is a civil engineer.
Marcie was first introduced as a camp attendee with Peppermint Patty in 1971. However, she is not given a name until later that year, on October 11th. The friendship between Marcie and Peppermint Patty started off unassumingly; with Marcie calling Peppermint Patty "Sir" in the very beginning, and Peppermint Patty calling Marcie a "dorky kid" in response. Over time, Marcie's character developed more fully, though she fits best as a supporting player and Peppermint Patty's best friend.
Marcie is an intellectual and a bookworm. She is well known for the high quality of her schoolwork, which provides a perfect contrast to Peppermint Patty's ineptness and has provided dozens of punchlines in the strip. She also has a talent for ice skating and music, she has taken organ lessons with Mrs. Hagemeyer (Miss Othmar's married name). Although not a hater of athletics (she admired the success of Billie Jean King, for example, and also likes caddying golf), her knowledge of sports often seems to be lacking and the rules appear to confuse her (Peppermint Patty: "There's no penalty box in baseball!").
Marcie also has a deep appreciation for the arts. In addition to her organ playing, many of the series' later gags involve her attending "Tiny Tots" concerts with Peppermint Patty, where she once again plays "straight man" to Peppermint Patty's cluelessness about the concerts themselves.
