Adrian Gecko, known in the Japanese version as
Amon Garam, is a student hailing from
East Academy who enters
Duel Academy in the third year. Reserved and secretive, Adrian is a neutral character whose actions seem to only serve the Gecko Family and himself. However, after obtaining the spirit of "
Exodia the Forbidden One" in the third alternate dimension, he intends to rule it as a world where darkness, and evil will vanish. He thus acts as a secondary antagonist towards Jaden and the primary antagonist,
Yubel.
