Jason Cross is a member of the East High School boys' varsity basketball team and one of Troy Bolton, Chad Danforth, and Zeke Baylor's good friends in High School Musical. He tends to ask questions or make statements that make him come off as a kiss-up or unintelligent. In High School Musical 2, he works as a bus boy at Lava Springs country club. Although High School Musical and High School Musical 2 hint at a possible relationship between Jason and Kelsi Nielsen, he attends prom with Martha Cox in the third film. He is played in the High School Musical movies by Ryne Sanborn. He did not make an appearance in Sharpay's Fabulous Adventure.
