<Li> Stevie Kenarban , played by Craig Lamar Traylor ( 56 episodes ) , is Malcolm 's best friend and classmate . He is wheelchair - bound and is missing a lung , requiring him to speak slowly and take deep breaths after saying a word . Though Malcolm is initially upset when Lois arranges a `` playdate '' for him and Stevie in the pilot episode , the boys immediately find common ground , particularly their love of comic books , and become friends . His parents are very overprotective of him , although Stevie displays in many episodes that he lives very comfortably with his disability and even has a dark sense of humor about it . </Li>
