The Great Leviathan (known as Orichalcos God in the Japanese version) was a giant serpent creature that intended to destroy the world. It employed the Orichalcos stones to corrupt people. It and it's followers destroyed Atlantis but the Great Leviathan was weakened and lied dormant in the ocean. Dartz gathered souls to revive it. Near the end of season 4 Dartz succeeds in awakening the Great Leviathan and merges with it. He battles Yami Yugi, Seto Kaiba, and Joey Wheeler but they defeat it. It lingers on in spirit form inside Dartz and attempts to turn Yami Yugi's darkness against him but Yami Yugi conquers his darkness. In the English dub Yami Yugi proceeds to seal away the Great Leviathan. In the Japanese dub Yami Yugi purges the darkness out of the Great Leviathan and it goes on to live in Duel Monsters Spirit World.

KC DuelTek 760


The Virtual dueling computer Yugi defeated at the start of the KC Grand Championship. Since it is a computer designed by KaibaCorp, its deck features cards from Kaiba's card database. It had 5 levels with varying decks. Zigfried von Schroeder briefly hacked into the computer, trapping them and forcing them to duel. Yugi dueled with Rick's deck. In its duel with Yugi it relied on a beatdown strategy with monsters like "Berserk Gorilla" and "Airknight Parshath", while depleting Yugi's hand with "Robbin' Goblin". Yugi countered its strategy using "Heart of the Underdog" a card he actually gave to Rick at the beginning of the previous episode and "Spirit Ryu" which gains more attack points depending on the number of dragons discarded to the Graveyard in the turn it was Summoned. In the end Yugi defeats the DuelTek and frees his friends.

Alex Brisbane
Professor Alex Brisbane is a direct descendant of Alexander the Great. He was working with Dr. Solomon Muto in India exploring a mysterious pyramid. They entered it and only Brisbane got out, Dr. Muto apparently disappeared in to thin air. Later, when Yugi and friends came, he led them to the chamber in the pyramid where Dr. Muto disappeared. It turns out that when professor Brisbane entered, he got possessed by the dark side of Alexander the Great and used Yugi and his friends to unleash the "ultimate power." He is voiced by Pete Zarustica in the dub.

Alexander the Great
The greatest conqueror in history, Alexander the Great was an ancient king who nearly conquered the world, and serves as the main villain during the Capsule Monsters mini-arc. Through his armies some of the ancient world's greatest nations fell before him, including Greece, Persia, and Egypt (the latter of which made Alexander into one of the great pharaohs). During his adventures Alexander came into possession of the Millennium Ring and began to carry it as a lucky charm. However, the ring soon began to cloud his mind, causing him to turn power-hungry and losing the respect of his troops (except for a handful of his servants). Wanting ultimate power Alexander was confronted by Shadi who told him to take the trial of the Capsule Monsters if he wanted the power. Alexander passed the trials, but was not allowed the power he wanted and his soul was trapped within the legendary Pyramid of Alexander (located in India). His spirit was also torn in two, one good (which was trapped within the game) and one evil (this one being trapped within the temple). Alexander's evil half would later possess his direct descendant.

After Yugi and friends passed the Capsule Monster trial (with the help of Alexander's good side), they crossed back into the pyramid and confronted Alexander's possessed descendant. He managed to steal an artifact that would allow him to unlock an ultimate power from within the temple. However, he was foiled by Yugi and friends and Alexander's dark half was banished forever, while his good side's spirit finally passed on to rest.

Oddly, he is larger than Yami Yugi.
