It first aired in Japan on January 19 , 2005 and in the United States on November 15 , 2005 . Summary . It ' s night at Duel Academy , and an Obelisk Blue student has just lost to a giant of a man , who takes the student ' s rarest card for winning . He tells him to learn from this experience , and walks off . The next day , Chumley Huffington relates a rumor to Jaden Yuki and Syrus Truesdale about a large Duelist who is being the card " The Duel Giant " , who has been challenging Obelisk Blue students to Ante Duel s in the dead of night . Dr . Crowler approaches them , and tells them he ' s giving them a special assignment to investigate the Duel Giant incident . They pay a visit to the Duel Arena , where an Obelisk Blue student is Dueling a small Ra Yellow student . The Obelisk has a Set card , 200 LP and " Marauding Captain " on the field , while the Ra has 300 LP and " Mad Sword Beast " . Jaden can spot " Earthquake " in the Ra ' s hand , which should allow him to win the Duel . However , he cannot make up his mind whether to play it first or simply attack . After some chiding from his opponent to hurry up , he attacks . The opponent activates his face - down " Reinforcements " , giving " Marauding Captain " 500 more ATK and the win . Bastion Misawa comments that the students name is Brier and he ' s a very good Duelist , but seems to suffer from a bad case of stage fright , which causes him to make mistakes . Brier departs the arena , and is seen with a much larger Ra who Bastion calls Beauregard . Syrus suspects he may be the Duel Giant simply due to his size , but Bastion reveals that he ' s at the Academy to become a game designer . Jaden chases them though , and accuses Beauregard of being the Duel Giant . Brier states he isn ' t , and the two depart . That night , the three hide outside the school and wait . They hear a scream , and run into the forest , finding the same Obelisk that Brier lost to , who has just lost to the Duel Giant . Jaden tracks the Giant down and challenges him , even agreeing to ante " Winged Kuriboh " . The Giant begins by Summoning " Giant Orc " in Attack Position , while Jaden plays " Winged Kuriboh " in Defense Position . The former then destroys the latter , but is also force to shift to Defense Position . However , the Giant Summons " Second Goblin " and equip s it to " Giant Orc " , allowing it to switch back into Attack Position . Jaden plays " Polymerization " , fusing " Elemental HERO Clayman " and " Elemental Hero Burstinatrix " to Fusion Summon " Elemental HERO Rampart Blaster " , using its effect to attack directly by halving its ATK while in Defense Position , with its ATK halved . This attack blows off The Giant ' s costume , which consists of tattered Obelisk Blue jackets , to reveal Beauregard . However , Jaden calls for the true Duelist to come out . Brier climbs out from behind a nearby rock , where he has been giving Beauregard instructions via headset . The two had teamed up to get back at the Obelisks who would always make fun of them - Brier for his short stature and Beauregard for his weight . Because he wasn ' t Dueling directly , Brier ' s true abilities were able to shine through and he won every Duel the Duel Giant had , in contrast to when he Duels in person and loses due to nervousness . Jaden convinces them to continue the Duel . Beauregard still wears the Duel Disk , but Brier gives him orders in the open , not via headset . He Summons " Goblin King " and then discard s " Warrior Dai Grepher " and " Big Shield Gardna " to Special Summon two " Half Goblin s " via their own effects . " Goblin King " gains 1000 ATK for every face - up Fiend - Type monster on the field , besides itself , so its ATK is currently 3000 . " Goblin King " destroys " Rampart Blaster " , while " Giant Orc " attacks directly before switching to Defense Position . " Second Goblin " switches " Giant Orc " back to Attack Position . Jaden draws and plays " Pot of Greed " to draw two more cards . He Summons " Elemental HERO Sparkman " and equips it with " Spark Blaster " , which he then uses to switch " Giant Orc " to Defense Position and the two " Half Goblins " to Attack Position . He then activates " The Warrior Returning Alive " to return " Clayman " to his hand before playing " Polymerization " to fuse it with " Sparkman " , Fusion Summoning " Elemental HERO Thunder Giant " . He uses its effect to destroy " Giant Orc " , with the equipped " Second Goblin " also being destroyed . He attacks and destroys a " Half Goblin " and then plays " De - Fusion " to split " Thunder Giant " and Special Summon " Sparkman " and " Clayman " who attack and destroy the second " Half Goblin " and " Goblin King " , winning Jaden the Duel . Beauregard begs Jaden to only turn him in , and leave Brier out of it . However , Jaden states he ' s not turning either of them in . However , this means they still have homework to do .
