Stewart Mango is a fictional cartoon character in the animated internet series The Mangos. He is voiced by Nicole Marie Doherty, as well as created by her.

Stewart's character originated from a boy that picked on Nicole in school. One day the boy just got on her nerves one day and she went to swing at him to make him leave her alone and she accidentally hit him and he ran away crying to the principal. Nicole was then suspended from school, but when she came back she drew a comic strip, like she would often do when something dramatic happens and over exaggerate it to make it funny, of the incident adding a comical ending in where the boy goes crying to his mommy. The comic then inspired her to make a series of this boy, then Stewart Mango was born. Stewart was meant to be this nasty, bratty kid who bragged and always had a frown on his face. After awhile she started to make Stewart cuter by putting a little smile on his face. Than she started to make Stewart more like her rather than the boy, by making him be the one who gets in trouble, while everyone else gets away with murder.

In The Mangos series Stewart is the unpopular kid. In reality he is a popular figure among students in Brick Memorial High School, school Nicole graduated from in 2008. He is also popular among students in Ocean County Vocational Technical School in Brick, New Jersey, where Nicole graduated from in 2008 as well. Stewart's character is mostly well known in Brick, New Jersey and is soon to spread to other places, which is though a website called YouTube, the popular video site.

Stewart is sarcastic as well as gullible. Although Stewart is an adorable little character, he can be a jerk sometimes. Even though Stewart seems stupid, he is actually the valedictorian of his class. Stewart is also conceded and thinks he's sexy, but girls always reject him, but this guy, Monte Balding, thinks he is sexy, but Stewart is creeped out by him.

Stewart's father, Mr. Mango, was the king of the planet, Mangee were his race, Mangeeians live. His mother is of course the queen of Mangee and also she likes to baby her children. Stewart's older brother, Journey, was going to be the king after his father, but his egg was dropped and he became dumb, so Mr. and Mrs. Mango had to produce another baby to take over the family throne.
During the time Mr. and Mrs. Mango were trying to make another baby and a king from another planet wanted them to bow down to his race, but Mr. Mango refused so the king sent out his horse/beaver/monkey artificially made people, called Jonathanians, to kill off the Mangeeians by ripping their hats off. After many Mangeeians were killed, the Mangos were powerless to defend themselves so they were able to escape on a space ship and they landed on Earth.
Earth was very different from Mangee and Mrs. Mango wound up laying an egg, which the Mangos thought the hatless Mangeeians (humans) did, but just kept their "egg" under their shirts, so Mr. Mango did the same, to fit in. Everything was going good until Mrs. Mango went to get an "ultra-sound thingie" on the egg and the baby kicked hard and the egg fell off. The doctor was not only freaked by the baby some how having a hat, but the fact that the pregnant stomach feel off, since Mangeeian eggs look like pregnant stomachs and get big like them. Eventually the egg hatched and Stewart Mango was born on April 20
