Wilson Schlamme is Jack's rival in the Goosebumps book How I Learned To Fly. He is better than Jack at almost everything and is extremely competative. They are also rivals for the affections of one of Jack's classmates, Mia.
One day, Jack finds a book with a top-secret mixture that will enable him to fly. But, to his dismay, Wilson copies him and can fly too. At the end of the book, Jack pretends to lose his flying capabilities, leaving Wilson stuck with the burden of celebrity while Jack gets the girl and his normal life back.
