Double Trouble Duel, Part 2, known as Integration of the Three Gods! Gate Guardian in the Japanese version, is the twentieth episode of the Yu-Gi-Oh! second series anime.


As Seto Kaiba approaches Pegasus' castle, he is confronted by Kemo, who pulls a gun on him, but Seto overpowers him and takes him hostage, demanding that he take him to Mokuba. Back at the Duel, Yugi and Joey bring out their strongest monsters, but the Paradox Brothers use Magical Labyrinth to change the shape of the maze and separate their monsters. Joey walks into Dox's Trap, Jirai Gumo, which destroys Axe Raider. Yugi destroys it with Mystic Box then has Dark Magician destroy Labyrinth Tank. Dox uses his powered-up Dungeon Worm to destroy Celtic Guardian. However, Joey uses Flame Swordsman equipped with Salamandra to destroy the worm. Unfortunately, the Paradox Brothers manage to draw all three pieces of Gate Guardian, their most powerful monster. Meanwhile, Kemo takes Kaiba through Pegasus' underground prison, but activates an alarm, forcing Kaiba to flee and find his little brother Mokuba himself. Can he? Will Yugi and Joey defeat Gate Guardian and win enough chips to enter Pegasus' Castle and leave the labyrinth for good?

Featured Duel: Yami Yugi & Joey Wheeler vs. Para & Dox

Duel continued from last episode.

Turn 8: Joey
Joey draws "Flame Swordsman" and subsequently Normal Summons it (1800/1600) in Attack Position. Since "Flame Swordsman" is a Level 5 monster, Joey can move it 5 spaces, but he chooses to move it only 4 spaces inside the maze, arriving at the same tile as "Celtic Guardian". He then moves "Axe Raider" inside the maze. Since it is a Level 4 monster, he moves it by 4 spaces. It joins "Flame Swordsman" and "Celtic Guardian".

Turn 9: Dox
Dox draws. He then moves "Labyrinth Tank" another 7 spaces.

Turn 10: Yami Yugi
Yami draws. He then Normal Summons "Dark Magician" (2500/2100) in Attack Position. Since it is a Level 7 monster, he can move it 7 spaces, but Yugi chooses to move it only 5 spaces inside the maze, in front of Celtic Guardian and Joey's monsters.

Turn 11: Para
Para draws "Magical Labyrinth" and subsequently activates it to change the shape of "Labyrinth Wall's" maze. "Flame Swordsman" and "Axe Raider" are separated from "Celtic Guardian" and "Dark Magician".

Turn 12: Joey
Joey draws. He then moves "Flame Swordsman" and "Axe Raider" ahead, but his "Axe Raider" steps on Dox's "Jirai Gumo's" space, causing it to appear on the field (2100/1000) in Attack Position and attack "Axe Raider". Due to the effect of "Jirai Gumo", the ATK of "Axe Raider" becomes its original ATK during the Damage Step ("Axe Raider": 2200 → 1700/1150). "Jirai Gumo" destroys "Axe Raider" (Joey 2000 → 1600).

Turn 13: Dox
Dox draws. He then moves "Labyrinth Tank" another 7 spaces, arriving right behind his "Jirai Gumo". He then Sets a monster ("Dungeon Worm").

Turn 14: Yami Yugi
Yami draws "Mystic Box" and subsequently activates it to force "Jirai Gumo" and "Dark Magician" to swap locations and destroy "Jirai Gumo". "Dark Magician" attacks and destroys "Labyrinth Tank" (Dox 2000 → 1900).

Turn 15: Para
Para draws "Sanga of the Thunder" and subsequently Sets it.

Turn 16: Joey
Joey draws. He then moves "Flame Swordsman" 5 spaces.

Turn 17: Dox
Dox draws "Suijin" and subsequently Sets it. He then Flip Summons "Dungeon Worm" (1800/1500) in Attack Position. He then activates "Invigoration", equipping it to "Dungeon Worm", increasing "Dungeon Worm's" ATK by 400, and decreasing its DEF by 200 ("Dungeon Worm": 1800 → 2200/1500 → 1300). Since it's a burrower, "Dungeon Worm" is able to move freely under the maze, bypassing the spaces and attacking any monster. "Dungeon Worm" attacks and destroys "Celtic Guardian" (Yami 1600 → 800). Shortly after, "Dungeon Worm" retreats underground.

Turn 18: Yami Yugi
Yami draws. He then activates "Magical Hats", hiding the "Dark Magician" and "Flame Swordsman" under two of four "Hats".

Turn 19: Para
Para draws. He then Normal Summons "Monster Tamer" (1800/1600) in Attack Position. Due to the effect of "Monster Tamer", Para can take control of Dox's "Dungeon Worm" as well as increase its ATK by 600 ("Dungeon Worm": 2200 → 2800/1300). "Dungeon Worm" attacks and destroys a "Hat", but it's empty. "Dungeon Worm" then retreats underground.

Turn 20: Joey
Joey draws. He then releases his "Flame Swordsman" from the "Hat" it was under. He then activates "Salamandra", equipping it to "Flame Swordsman" and increasing the ATK of "Flame Swordsman" by 700 ("Flame Swordsman": 1800 → 2500/1600). "Flame Swordsman" attacks "Dungeon Worm". The Salamandra attack can be steered through the air and down the tunnels, allowing "Flame Swordsman" to battle without moving and strike an underground monster. Also, since "Dungeon Worm" is weak against FIRE-Attribute monsters, it loses the ATK bonus it got from "Monster Tamer" ("Dungeon Worm": 2800 → 2200/1300). "Flame Swordsman" destroys "Dungeon Worm" (Dox 1900 → 1600).

Turn 21: Dox
Dox draws "Kazejin" and subsequently Normal Summons it (2400/2200) in Attack Position. He then Combines "Kazejin" (God of Wind) with the other two set monsters the brothers control: "Sanga of the Thunder" (2600/2200) (God of Thunder) and "Suijin" (2500/2400) (God of Water) to form "Gate Guardian" in Attack Position.

Turn 22: Yami Yugi
Yami draws. He then Sets 2 cards.

Turn 23: Para
Para uses the top-section of "Gate Guardian" (aka "Sanga of the Thunder": 2600/2200) to attack Joey's "Flame Swordsman".

Duel concludes next episode.

Differences in adaptations

  • The gun in Kemo's hand is erased from the dub.
  • Most of the fight between Kaiba and Kemo is cut out from the dub.
  • Shots of the Paradox Brothers are changed to show them talking in the US version. In the Japanese, they're just standing there looking fierce.
  • In the US, a spider graphic was added to the square Axe Raider steps on.
  • Mystic Box has a slightly different image in the dub.
  • A shot is changed in the US version to show the Jirai Gumo card being pierced by swords, rather than the monster itself.
  • The words "TO BE CONTINUED" are added at the end of the dub episode.


  • When Celtic Guardian gets destroyed by Dungeon Worm, Joey shouts, "No, my Celtic Guardian!" But Celtic Guardian belongs to Yugi, not Joey.
  • When Monster Tamer is Summoned, the graphic shows it with 1500 DEF when in both versions its card has 1600 DEF.
