Yu - Gi - Oh ! GX - Episode 055 A Hassleberry Hounding , known as Tyranno Kenzan Appears - saurus ! in the Japanese version , is the fifty - fifth episode of the " Yu - Gi - Oh ! GX " anime . Summary . Syrus and Jaden are walking through the woods . The duo got caught sleeping in class , so Crowler is making them deliver 14 new Duel Disks to students who had lost theirs . Jaden wonders why so many people were losing their Disks , and Syrus explains it ' s because of a bully that is challenging them to Duels and then taking them . Syrus had lost to this bully as well ( in the original , he ' s simply not wearing his duel disk out of fear of the bully ) , so Jaden decides it ' s time to confront this guy and get the disks back . They run to river , and standing on the bridge is the bully , Tyranno Hassleberry , the same Ra Yellow student that was picking on Crowler and Bonaparte when he arrived at the school . He tries to intimidate Jaden with his strength , but Jaden just shrugs it off and challenges him to a Duel . Hassleberry also has a bunch of other Ra Yellows who support him like an army troop . They and Syrus watch the Duel , and Jaden states that if he wins , Hassleberry has to give all the Duel Disks he stole back . Jaden starts off with " Elemental HERO Wildheart " in defense mode . On Hassleberry ' s turn , he summons " Gilasaurus . " When Summoned " Gilasaurus " can count as a special summon , so Hassleberry sacrifices him to summon his " Dark Driceratops . " He destroys Jaden ' s " Wildheart " and the effect of " Dark Driceratops " inflicts damage even though " Wildheart " was in defense mode , reducing him to 3200 Life Points . On Jaden ' s next turn , he activates the Spell Card , " Monster Reincarnation " , to discard his " Elemental HERO Necroshade " and bring back " Wildheart " to his hand . With " Necroshade " in the graveyard , Jaden Summons " Elemental HERO Bladedge " without a sacrifice and destroys " Driceratops , " reducing Hassleberry ' s Life Points to 3800 . Hassleberry ’ s troop cheers him on . He starts reminiscing about how he came to Duel Academy . Hassleberry was the son of an army sergeant and when he joined the school and aced his entrance exams , he thought he would go to Obelisk Blue , but got stuck in Ra Yellow . Even though he was in Ra , Hassleberry made the best of it and formed a troop to show people how much power and friendship means to him . Hassleberry plays a Field Spell Card , " Jurassic World " . It gives his Dinosaur s 300 extra attack and defense points , makes them immune to Trap Card s , and when they are attacked , they have the option of switching to defense mode . He then Summons " Archeonys " whose attack points raised to 600 and can attack Jaden directly , doing so to reduce him to 2600 Life Points . Hassleberry places one card face down to end his turn . Jaden Summons " Wildheart " again , and attacks with " Bladedge , " but Hassleberry uses his Trap Card , " Amber Pitfall , " which makes " Bladedge " switch to defense mode and forcing him to stay in defense . " Wildheart " attacks , but because of " Jurassic World " , " Archeonys " is switched to defense ( 1300 to 1600 ) , blocking the attack and causing Jaden to lose 100 life points . He places two cards face - down to end his turn . Hassleberry activates " New Ultra Evolution " , which let him sacrifice " Archeonys " to summon his " Black Tyranno " with 2600 ATK , raised by " Jurassic World " to 2900 , whose special ability allows it to attack Jaden directly . He survives the attack , thanks to his " Insurance " Trap Card : By returning it to his hand , Jaden was given 500 extra Life Points . Meanwhile , Hassleberry notices that his troop is getting bored and no longer cheering him on . He explains that every time he starts a troop , they always leave him when he needs them . He has also used the exact same Dueling strategy for each of his Duels . Jaden tries to teach Hassleberry that he ’ s stuck in the past and needs to learn to change his strategy if he wants to keep his friends , suggesting that he " evolve . " Jaden plays his own Field Spell , " Skyscraper " , to replace " Jurassic World , " reducing " Dark Tyranno ’ s " ATK back to 2600 . Jaden then plays " Polymerization " to fuse " Elemental HERO Avian " and " Wildheart " to summon " Elemental HERO Wild Wingman , " whose special ability lets Jaden discard a card to destroy " Amber Pitfall . " " Wildwingman , " whose ATK is raised to 2900 due to " Skyscraper , " attacks " Dark Tyranno , " and then " Bladedge " attacks directly . Hassleberry thinks that he ' s still safe , but Jaden then plays " De - Fusion " to separate " Wildwingman " into " Avian " and " Wildheart , " and " Avian " attacks directly , winning Jaden the Duel . After the Duel , Hassleberry agrees to give back the Duel Disks . Later that night , Hassleberry moves to the Slifer dorm , having decided to live in the dorm because he feels that he could learn a lot about Dueling from Jaden . Featured Duel : Jaden Yuki vs .
