Yu - Gi - Oh ! 5D ' s - Episode 129 " Fight to the Finish Line " , known as " Gjallarhorn ! Countdown to the End " in the Japanese version , is the one - hundred and twenty - ninth episode of " Yu - Gi - Oh ! 5D ' s " . Halldor reads Yusei ' s miraculous move and cuts it in half , and begins his own counterattack . And after activating " Gjallarhorn " , he states to Yusei that he has three turns to survive the Duel before his Trap takes out the remainder of Yusei ' s Life Points . On the other hand , Yusei manages to surpass the attack of the Gods , preforming an Accel Synchro . His final trump card , " Shooting Star Dragon " is Summoned ! It ' s become a fight of Shooting Star Dragon VS The Three Aesirs of Asgard ! Summary . Halldor ' s " Gjallarhorn " has protected his " Aesirs " from Yusei ' s Trap , and furthermore , Yusei now has three turns left to win the Duel . Facing down the three " Aesir , " which all grant beneficial bonuses to Halldor when they are revived by their effects , Yusei can only defend with " Stardust Phantom , " which when destroyed will allow him to Special Summon " Stardust Dragon " back from his Graveyard and have it lower its DEF by 800 to prevent its destruction , allowing him to weather all three of the " Aesir ' s " attacks . But Halldor gains an extra chance with the effect of " Speed World 2 , " destroying " Stardust Phantom " and Summoning " Stardust Dragon , " but now he has enough attacks to destroy " Stardust Dragon . " In turn , Yusei counters with his " Stronghold Guardian " to give " Stardust Dragon " enough DEF to survive the attacks . Halldor then shortens Yusei ' s time to win even further , by Summoning " Jormungardr the Nordic Serpent " and " Fenrir the Nordic Wolf " to Yusei ' s field . " Jormungand " will inflict 3000 damage to Yusei when switched to Attack Position , while " Fenrir " not only inflicts any battle damage it inflicts to both players , but also forces Yusei ' s monsters into Attack Position during his Battle Phase . Rather than falter , Yusei instead uses " Hope for Escape " , taking advantage of his Life Points being so much lower than Halldor ' s to draw more cards , then uses the new cards to bring out " Formula Synchron " while also getting rid of " Jormungand " . With the Mark of the Crimson Dragon behind him , he accelerates , performing an Accel Synchro to call out " Shooting Star Dragon " , and then uses " Speed Spell - Star Force " to Release " Fenrir " and power up " Shooting Star Dragon " . Yusei then utilizes the effect of his " Shooting Star Dragon " and he gets three Tuner monsters , so " Shooting Star Dragon " gains three attacks . Yusei ' s monster then destroys all three " Aesirs " which only angers Halldor even more . Halldor notes if Yusei had gotten a fourth Tuner he could have attacked him directly and win . The " Aesirs " all revive , and Halldor decides to end the Duel now . Halldor uses " Odin ' s Eye " again , but also uses the effect of " Tyr of the Nordic Champions " to make his Aesirs immune to " Odin ' s Eye " this turn . Before he can find out what Yusei ' s plan is , Yusei quickly uses " Trick Mirror " to make the effect of " Odin ' s Eye " the effect of " Trick Mirror " instead . As a result the effects of the " Aesirs " are negated . Halldor then tries to attack with " Odin " , but Yusei uses the effect of " Shooting Star Dragon " to remove his monster from play and negate the attack . Halldor doesn ' t care as Yusei ' s only monster is gone now so he prepares to attack with " Thor " or " Loki " . Yusei smiles and activates " Zero Force " to reduce the ATK of all of Halldor ' s monsters to 0 . Halldor becomes shocked at what Yusei has just done and realizes he can no longer use his " Aesirs " for attacking . The final effect of " Gjallarhorn " then activates , removing all three " Aesirs " from play and inflicting their total ATK to Yusei as damage , however since they had 0 ATK when this occurred , Yusei takes no damage . Halldor is even more shocked that Yusei outsmarted his tactics and Dragan is angered that the gods were defeated . Jack notes now that the " Aesirs " have been removed from play , Halldor can ' t use their effects to revive them . Yusei ' s " Shooting Star Dragon " then comes back due to its effect and Yusei immediately has it attack Halldor directly and win the Duel , which frustrates Dragan and Broder greatly as Halldor and Yusei come back . Featured Duel : Yusei Fudo vs . Halldor . Turn 20 : Halldor Halldor has just activated " Gjallarhorn " in response to Yusei activating " Wave Rebound " to negate the Summons of the " Aesir s " and inflict their combined ATK as damage to Halldor . Due to the first effect of " Gjallarhorn " , the Special Summoning of the " Aesirs " can ' t be negated this turn , so " Wave Rebound " resolves without effect . Halldor explains that during his third End Phase after the activation of " Gjallarhorn " , its second effect will remove itself and the three " Aesirs " from play and inflict damage to Yusei equal to the combined ATK of all three . Halldor ' s hand contains " Birthright " and " Soul Resurrection " . " Thor , Lord of the Aesir " ( 10 / 3500 / 2800 ) , " Loki , Lord of the Aesir " ( 10 / 3300 / 3000 ) , and " Odin , Father of the Aesir " ( 10 / 4000 / 3500 ) are all revived in Attack Position via their own effects . The secondary last effects of the " Aesirs " then activate . The final effect of " Thor , Lord of the Aesir " resolves first ( Yusei 2000 → 1200 ) . " Loki , Lord of the Aesir " allows Halldor to add " Odin ' s Eye " from his Graveyard to his hand . Finally , the effect of " Odin , Father of the Aesir " allows Halldor to draw a card ( " Miraculous Descent " ) . On Halldor ' s End Phase , Yusei is forced to remove the last Chain Counter on " Monster Chain " ( Chain Counters : 1 → 0 ) . Since " Monster Chain " has no more Chain Counters , it is destroyed . Turn 21 : Yusei Fudo Yusei draws " Stardust Phantom " . During the Standby Phase , the effect of " Speed World 2 " activates ( Yusei ' s SPC : 1 → 2 ; Halldor ' s SPC : 8 → 9 ) .

Yusei then activates the " Stardust Phantom " - granted effect of " Stardust Dragon " in order to prevent its destruction ( " Stardust Dragon " : 1000 → 200 / 1900 → 1100 ) . Halldor then Special Summons " Jormungardr the Nordic Serpent " ( 8 / 3000 / 3000 ) to Yusei ' s side of the field in Defense Position via its own effect ( as Halldor controls a Divine - Beast - Type monster ) . When " Jormungardr " is switched from Defense Position to Attack Position , Yusei will take 3000 damage .

The difference between Yusei and Halldor ' s Life Points is at least 3000 and less than 4000 , so Yusei draws three cards . Yusei then Normal Summon s " Life Gardna " ( 1 / 0 / 800 ) in Attack Position . He then removes from play " Jormungardr the Nordic Serpent " in order to Special Summon " D . D . Sprite " ( 1 / 0 / 100 ) in Attack Position . Yusei then tunes " Life Gardna " with " D . D . Sprite " in order to Synchro Summon " Formula Synchron " ( 2 / 200 / 1500 ) in Attack Position . Since " Life Gardna " was sent to the Graveyard , its effect activates , increasing Yusei ' s Life Points by 800 ( Yusei 200 → 1000 ) .

" Fenrir the Nordic Wolf " is Level 10 ( " Shooting Star Dragon " : 3300 → 4300 / 2500 ) . Yusei then activates the first effect of " Shooting Star Dragon " to reveal the top five cards of his Deck and allow " Shooting Star Dragon " one attack for each Tuner Monster he finds . Yusei finds " Junk Synchron " , " Nitro Synchron " , " Turbo Synchron " , " Sonic Chick " , and " Scrap - Iron Scarecrow " , so " Shooting Star Dragon " gains three attacks . " Shooting Star Dragon " attacks and destroys " Thor , Lord of the Aesir " , " Loki , Lord of the Aesir " , and " Odin , Father of the Aesir " ( Halldor 4000 → 3200 → 2200 → 1900 ) .

Halldor then activates his face - down " Odin ' s Eye " and Tributes " Tyr of the Nordic Champions " to prevent the " Aesirs " from having their effects negated by his card effects this turn . Before Halldor can activate the effect of " Odin ' s Eye " to see what one of Yusei ' s Set cards is , Yusei activates his face - down " Trick Mirror " to activate the effect of " Odin ' s Eye " as the effect of " Trick Mirror " instead ( since this has the effect of the effect of " Odin ' s Eye " shift sides rather than outright stopping the effect of " Odin ' s Eye " , the card is not being negate d , so " Odin ' s Eye " cannot stop the effect of " Trick Mirror " ) , which means the effects of the " Aesirs " are negated and Halldor must show all cards he currently has in his hand to Yusei . " Odin , Father of the Aesir " attacks " Shooting Star Dragon " , but Yusei activates the third effect of " Shooting Star Dragon " to remove it from play and negate the attack . Halldor prepares to attack directly with " Thor " or " Loki " , but Yusei activates his face - down " Zero Force " to reduce the ATK and DEF of all monsters on the field that had equal or higher ATK than " Shooting Star Dragon " to 0 ( " Thor " : 3500 → 0 / 2800 → 0 ) ( " Loki " : 3300 → 0 / 3000 → 0 ) ( " Odin " : 4000 → 0 / 3500 → 0 ) .
