Cynthia Sanders, played by Tania Raymonde, is a new and outgoing Krelboyne girl who joins Malcolm's class in the episode "Krelboyne Girl." Cynthia is one of Malcolm's first crushes throughout the series but quickly takes on the role of a caring and compassionate friend. She knows Krav Maga, which she promptly uses to subdue Reese when his behavior becomes too annoying to her. She is cited as also having very large breasts for her age. In season three her prolonged absence is explained by stating that she has returned from Europe. After sharing a brief romance with Reese (in which he is only trying to take advantage of her to see her breasts) she returns in the season four episode "Humilithon," she saves Malcolm from making a horrible mistake by implying that they have shared an intense romance; destroying her own reputation in the process. After this episode she is never seen again and there is no explanation as to what became of her.
