"A New Threat, Part 2", known as "Proof of Evolution, Synchro Monster" in the Japanese version, is the sixty sixth episode of Yu-Gi-Oh! 5D's. It first aired in Japan on July 8, 2009 and in the United Sates on September 25, 2010

Yusei continues to Duel the mysterious Turbo Duelist Ghost, who possesses a creature that can absorb his Synchro Monsters. At the end of the Duel, Yusei is shocked to discover the true identity of the Ghost.


Yusei's base

As the sun rises in New Domino City, Leo and Luna dash through a medieval-style town to a building called Poppo Time. They shout Yusei's name, but notice he is not around. Instead, they find Akiza standing over a desk. Although neither her nor Luna are getting a reaction from their Marks of the Dragon, Akiza has the feeling that Yusei is dueling someone right now.

The Duel

Yusei continues his Duel with Ghost, while Crow and Jack watch from adjacent lanes. Crow and Jack meet up and notice Yusei is facing a large monster but then see it is 5 smaller ones. Regardless, they believe Yusei should be able to win. Yusei Sets 2 cards in his Spell & Trap Card Zone and ends his turn.

Ghost begins his turn, raising both duelists' SPC to 2. He has "Machine Emperor Wisel Infinity" attack "Max Warrior", but Yusei activates "Shock Reborn", to halve the Battle Damage. "Max Warrior" gets destroyed and Yusei's Life Points drop to 3150. Using the other effect of "Shock Reborn", Yusei revives "Turbo Booster". Ghost sets 1 card face-down into his Spell & Trap Card Zone and ends his turn snickering.

Yusei begins his turn and both duelists' SPC increase to 3. Yusei starts to think about "Meklord Emperor Wisel Infinity's" effect. Considering his options, he looks at his cards on his field; "Turbo Booster" and a face-down Spell or Trap Card and the cards in his hand; "Gauntlet Warrior", "Speed Spell - Angel Baton" and "Debris Dragon", and devises a way to Summon "Stardust Dragon" and combine it with "Meteor Wave". He activates "Speed Spell - Angel Baton", sending "Gauntlet Warrior" to the Graveyard to draw 2 cards. Next, he Summons "Debris Dragon" and uses its effect to revive "Gauntlet Warrior". By tuning "Turbo Booster", "Gauntlet Warrior" and "Debris Dragon", he Synchro Summons "Stardust Dragon". Yusei then activates his face-down "Meteor Wave", raising "Stardust Dragon's" ATK to 2800, making it higher than "Meklord Emperor Wisel Infinity's". He has it attack "Infinity", but Ghost activates the effect of "Wisel Guard" making it the attack target. "Meklord Emperor Wisel's" arm takes the hit and gets blown off, but, due to "Meteor Wave's" second effect, since the monster affected by it had attacked a monster in Defense Position, Ghost receives Piercing damage. Ghost's Life Points drop to 2400, while Yusei Sets a card in his Spell & Trap Card Zone and ends his turn.

Ghost looks up Yusei's data on the monitor of his Duel Runner. He sees that Yusei defeated Rex Goodwin and laughs that Yusei is still clueless.

Ghost begins his turn and each duelists' SPC increase to 4. He Summons "Wisel Guard 3", which replaces "Meklord Emperor Wisel's" missing arm. Ghost laughs that "Wisel" is invincible, but Yusei thinks he should be able to beat if he can take out all the components at once.

Yusei asks Ghost why he is targeting Duel Runners, and Ghost replies that it is his purpose. He claims to be the Synchro killer and uses "Meklord Emperor Wisel Infinity's" effect to equip itself with "Stardust Dragon". "Meklord Emperor Wisel" fires a number of energy beams, which strap themselves to "Stardust Dragon". "Stardust Dragon" begins to struggle but is sucked into the machine. Yusei then remembers Trudge warning him not to use Synchros against Ghost. "Machine Emperor Wisel Infinity's" ATK rises to 5000.

"Meklord Emperor Wisel" attacks Yusei directly, but Yusei uses "Scrap-Iron Scarecrow" to negate the attack. Ghost Sets 2 cards in his Spell & Trap Card Zone and ends his turn.

Yusei begins his turn and both duelists' SPC rises to 5. Yusei Summons "Bicular" in Defense Mode and Sets 1 card in the Spell & Trap Card Zone, before ending his turn.

Both duelists' SPC increase to 6 and Ghost activates "Wise A3", Special Summoning "Wisel Attack 3". It folds out into an arm an attaches itself to "Meklord Emperor Wisel", raising its ATK to 5400. "Meklord Emperor Wisel Infinity" attacks "Bicular". Yusei plays "Scrap-Iron Scarecrow" again. However, Ghost activates his face-down, "Battle Return", lowering "Meklord Emperor Wisel Infinity's" ATK to 2700, so it may attack again. It attacks and takes out "Bicular", causing Yusei to struggle to maintain control of his Duel Runner. "Meklord Emperor Wisel Infinity" then inflicts damage to Yusei equal to "Stardust Dragon's" ATK, dropping his Life Points to 650. Using "Bicular's" effect, Yusei Special Summons "Unicycular". Ghost activates "Trap Recycle", returning "Battle Return" to his hand, alongside "Reload" and ends his turn.

Jack yells at Yusei to fight back. Yusei begins his turn, drawing "Sonic Chick" and both duelists' SPC increase to 7. Yusei uses "Speed World 2's" effect to remove his 7 Speed Counters to draw a card. Yusei concentrates and his Mark of the Dragon starts to glow. Crow and Jack notice theirs glowing too. Back in Poppo Time, Akiza and Luna's have started glowing too. The birthmarks all disappear and form the complete dragon on Yusei's back. The top card on Yusei's Deck starts to glow. He dramatically draws the card, "Majestic Dragon" and Summons it. Yusei then activates "Synchro Material" returning "Stardust Dragon" to his side of the field. Tuning "Majestic Dragon" with "Stardust Dragon" and "Unicycular", Yusei Synchro Summons "Majestic Star Dragon". "Majestic Star Dragon", which has 3800 ATK, attacks "Wisel Top", which has 500 ATK. "Wisel Top" gets destroyed decapitating "Meklord Emperor Wisel", which subsequently gets destroyed. Ghost's Life Points drop to 0 and his Duel Runner strays off course, plummeting off the bridge and exploding.


Down below in the woodland area, where Ghost crashed, Primo walks over to the charred Duel Runner. He removes a part from the Duel Runner, containing the Deck and looks up at "Majestic Star Dragon", believing Yusei to be responsible.

After Primo has left, Yusei, Jack and Crow arrive at the scene. Crow touches Ghost, then jumps back in alarm as his robotic arm falls off. Yusei deduces that Ghost is just a robot.

Back at the base, Trudge, who has recovered from his encounter with Ghost, Mina, Luna, Leo, Akiza, Jack, Yusei and Crow gather around a table inspecting photos Trudge tells them that Ghost was a Duelbot. As they wonder who is behind the Duelbots, Yusei gives Trudge a chip from his Duel Runner, saying it was programmed to erase all its data when it lost. Trudge is surprised Yusei can access the CPU so easily, then Crow says it was easy for Yusei and he is better than Security. As they ponder on recent happenings, Yusei thinks to himself that they are about to face a new threat.

Differences in adaption

When Ghost looked up Yusei on his Duel Runner and realized he had beat Rex Goodwin he said it made sense since as he figured Yusei was no ordinary fellow. In the dub Ghost says he should be quaking in his boots but then says it isn't his style.


  • In the English version, when Yusei took half the battle damage through "Shock Reborn", the ATK meter was shown instead of the Life Point meter.
    • It also included a Level meter, showing that Yusei is apparently a Level 1 monster.
  • In the English version, during the explanation of "Wisel Guard 3", the monster was mistakenly labeled an EARTH attribute, however it explained that it was a DARK monster.
    • This is similar to an error made in the Japanese version, where the entire "Wisel" series was shown as EARTH during their first appearance when they were in fact DARK.
  • In the English version, after the Ghost ended his turn, Jack, Crow and Yusei all stated Yusei had one last turn left. This is false, as he had two turns left as he could've used Scrap-Iron Scarecrow as Battle Return cannot be set until his next turn.
  • In the English version, the explanation of Wisel Guard 3's effect was presented incorrectly. Wisel Guard 3's effects are the following: You can direct an opponent's attack to itself instead. Once per turn, Wisel Guard 3 cannot be destroyed by battle.
  • Ghost appeared to have three Wisel monsters before he ended the third turn. However this third Wisel part is not seen later on and it appears to have been replaced with "Reload" or "Wise A3".
  • In the original, Yusei incorrectly says he negated all the parts of "Meklord Emperor Wisel", when he actually only negated "Wisel Guard 3".
