Yu-Gi-Oh! - Episode 150

=Alister Comes Into The Scene.=
 * Alister has activated "The Seal of Oreichalcos", isolating him and Seto Kaiba from any interference and determining that whoever loses the Duel will lose his "soul".
 * When Seto demands an explanation, Alister holds out a charred action figure from his pocket. Kaiba mocks it as a piece of junk, but when Alister declares that it used to belong to his brother, both Seto and Mokuba are dumbstruck.
 * Alister goes on to tell that he grew up in a war zone with his little brother Mikey as his only family. When the fighting grew worse, the two of them had to surface from shelter and move elsewhere.
 * For a moment, their side gained an advantage, bringing out a fleet of recently-purchased KaibaCorp tanks. But when Alister helped Mikey into a tank so as to escape, he had to go back to pick up Mikey dropped locket of their mom. The tank was bombed, and Alister was faced by a fleet of enemy choppers, knowing by the flames of the tank near him that his brother was dead.
 * Picking up the burnt toy that was all he had left of his brother, he looked and saw a man in a red suit shaking hands with the enemy troops. Suddenly, he was shown Dartz with his mantle on.
 * Dartz: "Do you know whom that man is? He is Kaiba Gozaburo. He is the President of Kaiba Corporation."
 * Alister: "Kaiba... Corporation...?"
 * Dartz: "Indeed. He is the true killer of your brother. He is the man who sold weapons to both sides for field testing."
 * Alister: "That can't be...!"
 * Dartz: "Do you wish revenge against that man?"


 * Alister nods in agreement.
 * Alister vowed to have revenge against KaibaCorp, and Seto is included in this. Even the clothes and food Seto and Mokuba live by are paid for by KaibaCorp.
 * Although Mokuba is rattled by these accusations, Seto is not as moved, and their Duel continues.

=Alister's Tactics.=


 * The Duel beings going badly when Alister reveals a strategy that pulls Kaiba's Monsters to Alister's Field, adding to the power afforded by the Seal.
 * Kaiba attempts to counter the power strategy by setting his favored Crush Card Virus, but Alister anticipates this move immediately, Activating Royal Decree to prevent the Virus from being used. Then, his attacks wipe out Kaiba's defense and many of his Life Points.
 * Kaiba rallies the power of his Deck, unleashing a combo which breaks Alister's Monsters and finishes the Turn with two Blue-Eyes White Dragons on his Field.    * Alister retaliates with a simple combo that pulls both of those Dragons to his side alongside his trump Card. With three opposing Monsters clearing 3000, 3500 and 3500 ATK each, Kaiba is out of his depth, and he knows it, since he doesn't have a Monster which can be summoned without Tribute nor any God Card.

=The Second Dragon.=


 * Just as his options seem to be gone, his Deck responds with a bright glow which transports him to another world. He arrives before a crystal statue of a dragon with a sword thrust in it. Seto Kaiba removes the sword, unlocking "The Fang of Critias" from its prison and bonding to it.
 * Yugi & co., heading to the Industrial Illusions HQ, see how "The Eye of Timaeus shines for a split second.
 * Back in the real world, Kaiba takes his Draw Phase, drawing Critias. He instantly uses him with his dormant Crush Card, summoning Doom Virus Dragon, which wipes out all of Alister's Monsters at once.
 * Just before Kaiba's new dragon delivers the finishing attack, Alister activates a Spell which ends the Duel in a Draw. A beam of green light shoots up from the depths of the "Seal", knocking Kaiba back. When he looks up again, Alister is out of sight but claims that he will have his revenge.

=Notes=
 * Most of Alister's flashback is kept in the English dub. However, the dub does not include the moments when the tank bearing Mikey is bombed. As the battle concludes and young Alister finds himself alone, it is instead stated that Mikey was captured.
 * In the English dub, Kaiba is called to set Critias free by the voice of Dark Magician Girl. He takes the sword, muttering, "Anything to shut you up." In the Japanese version, no one tells Kaiba to do anything. He frees and recognizes Critias on his own.
