Amanda Martin is one of the major kid characters of The Fairly OddParents: The Next Generation. She's a rich and popular 10-year old girl, Marty's (and formerly Tommy's) love interest and Jessie's friendly rival. Amanda lives in the Martin mansion, which is said to be bigger than the Tang and Buxaplenty mansions combined. Amanda is popular among not only kids, but teachers as well, as she's considered by them as a "teacher's pet".
Amanda has long blonde hair (she's later revealed to be a brunette) and blue eyes. She wears a dark purple shirt, a red bracelet, white earrings, a pink skirt, white tights and blue boots. Amanda uses pink lipstick and has pink fingernails. Her voice is similar to Starfire from Teen Titans.
Amanda's personality is similar to that of Trixie Tang when she was her age, always asking boys to tell her that she's pretty. Much like younger Trixie, Amanda can be a bit of a wisecracker. Despite that, she is a really kind girl. Amanda likes swimming, money, looking pretty and playing billiard and has a soft spot for other kids, such as Otto, her boyfriend Marty, and her friendly rival, Jessie. She likes to blackmail people that she really hates. Inside a popular girl in school lies the heart of a girl who's neglected by her parents in favor of her siblings. Similar to Remy Buxaplenty, who was also neglected by his parents, Amanda reserves fairy godparents, and couldn't be any happier.
