Trivia

 * Although he serves as the main antagonist of the entire first half of the Battle City arc this was done in order to hide the arcs true villain.
 * In both the manga and the Japanese version of the anime Marik aimed to seek vengeance against the pharaoh/Yami Yugi because he believed he killed his father (until he finds out who the real culprit is) however this was changed to him simply wanting to take over the world in the 4Kids dub.
