Adrian Gecko, known as Amon Garam(アモン・ガラムAmon Garamu) in the original Japanese language version, is a fictional character in the Yu-Gi-Oh! GX anime series. His given name in the Japanese version is an alternate spelling of the name of an Egyptian air deity, Amun. In the Japanese version, Amon is voiced by Saichouya (older) and Saori Terai (younger). A quiet and secretive duelist, Adrian is introduced during the third season as a neutrally-aligned character, who ultimately becomes one of its main antagonists nearing the end of the season.
