Darknite is a villain that appears in some of the Yu-Gi-Oh! games, but not in the main series. He serves as a Bigger Bad in every case. In the Japanese version, he is called Card Majin, which (in Japanese culture) a Majin is a malicious deity that causes disaster with it's mere presence. He could also be considered one of the most evil (or at least the source of it) entities in the series, due to him creating the Shadow Games. Darknite can also transform into a more powerful form known as Nitemare.
