Cody

Cody is a Magikoopa who is a friend of Bowser Junior. He first appeared in the Bowser Junior's Summer School series, but he has since became a recurring character in other videos. He is the only character introduced in the Summer School series to appear outside of the series. He is a stereotypical nerd with a bunch of medical disorders, though it has never been specified exactly what they are. He only came to summer school not because he failed, but because he wants to learn more. After the Summer School series, he is usually seen with a Ken doll (not the same one he bought in Bowser Junior's Summer Vacation) sitting on his shoulders.
