Adrian Gecko, known in the Japanese version as Amon Garam is a new 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 acquiring the spirit of "Exodia the Forbidden One" in the third alternate dimension, he intends to rule it and acts as a secondary antagonist towards Jaden and the main antagonist, Yubel.

His given name in the Japanese version is derived from an alternate spelling of the name of an Egyptian air deity, Amun.



In the English dub, Adrian presents himself as somewhat of a party animal, and is witty to point where sometimes pokes fun at the series (an example is when he says he activates a card by calling its name dramatically).

His original series counterpart instead possesses a flexible intellect capable of immediately dealing with any opponent and takes a highly philosophical approach as a duelist, once quoting René Descartes "Cogito ergo sum" to express the meaninglessness of passionate battles such as the Survival Duels announced by Professor Viper.




Adrian is the eldest son of the Gecko Family (Garam Group; ガラム財閥, Garamu Zaibatsu), which has considerable influence over the world's petroleum, heavy chemical industry, and information technology. Abandoned by his father when he was young, Adrian developed an inferiority complex that convinced him that he had nothing left to live for. He observed the sky and awaited death, but was one day adopted by the Gecko Family which intended for him to become its heir in light of the family's failure to produce a biological child to fill the position. However, when a son named Shido was at last conceived, Adrian grew jealous of his younger brother (in the Japanese version, he contemplates killing him), but chose to continue working diligently for his sibling's sake. In the English dub, It states that he completely forgot about his vendetta during the timeskip.

From the outset of the third year, Adrian works undercover to learn more about Viper's plot. He is eventually approached by Professor Viper himself, who threatens to return him to East Academy if he refuses to Survival Duel. Suspecting that he will set the Bio-Band energy absorption level on maximum—which can cause death—for his scheduled Duel, Adrian invites students to a party to participate in Survival Duels with one another, intending to overload Viper's project. As he leaves the Obelisk Blue dormitory, however, Chazz lifts him off the ground by helicopter, challenging him to a duel. Intrigued by Chazz's determination stemming from his time at North Academy, Adrian reveals the hellish past that he too has suffered. Despite this similarity, he concludes that Chazz is "nothing special," and although he wins the duel, the energy absorption level on his Bio-Band was not minimized enough to prevent him from collapse.

After recovering from the duel, Adrian infiltrates Viper's hideout. The two spar for ownership of a certain card that Viper possesses, of which the Gecko Group holds interest, but the spirit within the Survival Duel energy chamber restrains Adrian just as he seems to gain the upper hand. Managing to temporarily short circuit the facility’s power source, Adrian escapes and finds the machine responsible for Survival Duel energy absorption, but succumbs to the darkness of his heart and chooses not to shut it down.

While trapped in the alternate dimension along with Jaden Yuki and company, Adrian teams up with them to fight off the duel zombies, but mysteriously erases a file about him while on a Gecko submarine, trying to get medicine for an ill Blair Flannigan. On numerous occasions, he meets Marcel who was possessed by Yubel. Asking Yubel why it didn't choose him to use its power, Yubel mockingly replies that Marcel had an unexpected and greater darkness in his heart at the time. Enraged over this, Adrian continues to monitor Yubel and ends up stranded in the alternate dimension after Yubel is defeated by Jaden and Jesse.

Adrian later reappears in the third alternate dimension after the fall of Haou the Supreme King with his left arm imbued with a portion of Yubel's power. Intending to become the dimension's king, he sacrificed the only woman he ever loved, Echo, to free the spirit of "Exodia the Forbidden One" from imprisonment and make it his servant, defeating Aster Phoenix in the process. He meets up with Jesse (possessed by Yubel) in Yubel's castle to prove he is worthy of being king, but is defeated, feeling the pain of losing Echo a second time beforehand, and dies because losing a duel in that dimension results in death. During that the duel he revealed that he intended to become the dimension's king with intent of ridding the world things such as poverty and suffering, which Yubel mocked him for. Also, it turned out that he never stopped loving Echo, and she also still loved him.

Adrian is seen one more time prior to Jaden's duel with Yubel, as Jaden remembers all the people Yubel has wronged.

Although its later revealed that everyone who died in that world was actually trapped in yet another alternate dimension, after Jaden's final duel with Yubel everyone else returns to Duel Academy except for Adrian, Zane, Bastion, and Jaden himself. The press release for episode 157 indicates that he survived and was on the boat departing Duel Academy. He presumably returned to East Academy.

  • Adrian bears a resemblance to Kaz Kalinkas from Chaotic (notice the similar spiky hair). Both Kaz and Adrian are voiced by Darran Dunstan.




Opponent Outcome
Chazz Princeton Win
Marcel Bonaparte/Yubel No result

Adrian plays a Cloudian Deck. His cards take advantage of a unique set of abilities, including monster destruction via Fog Counters and Direct Damage. The summoning speed of his monsters is strengthened by "Summon Cloud" and "Big Summon Cloud", which allow him to instantly call forth his Cloudians as long as they are in his hand. In desperation, he can also activate Wonder Cloud, removing almost all his cards from play to draw more cards. His signature card, "Cloudian - Eye of the Typhoon", is capable of shifting the battle positions of all his opponent's monsters the moment it strikes.



Opponent Outcome
Aster Phoenix Win
Jesse Anderson/Yubel Lose

After making his reappearance in the third alternate dimension after The Supreme King is defeated, he adopts Yubel's Exodia Deck and focuses on the gathering of the five pieces of Exodia. If the initial strategy fails, he can also summon "Exodius the Ultimate Forbidden Lord", allowing him to achieve the same results as the above strategy by gathering all the pieces in his graveyard. As a back strategy he can also try win using the combination of "Fog King", "Royal Sword", and "Fog Castle", if that strategy also fails his last move is to try and gather the five pieces of Exodia by the effect of Fog Castle and Break the Seal.

Opponent Outcome
Alexis Rhodes and Bastion Misawa Lose (with Jesse Anderson)
