It first aired in Japan on December 26 , 2007 . Summary . Hassleberry and Blair have finished the graduation album photos and hand the containing them to Dr . Crowler . He previews the photos , and privately seems upset that everyone is growing up and leaving Duel Academy . Meanwhile , Jaden has been skipping classes again , and Hassleberry and Blair inform him that Crowler ' s manner has changed . He chastises the third year students , making them do tests in basic math to ensure they can calculate Life Points , write to understand card effect s , and even makes them do . He then begins canceling classes , and the students begin to fear that they won ' t have sufficient grades to graduate if he keeps doing so . Crowler goes to great lengths to hide from his students , and this ultimately results in a chase across the Academy , even leading them through Chancellor Sheppard ' s office . They finally corner him , and he states he won ' t allow them to graduate . Jaden asks why , and Crowler reveals that Jaden himself does not have sufficient points to graduate and even calls him " drop - out boy " , something he hadn ' t done in long time ( This expression is changed to " Slifer Slacker " in the dub ) . Jaden challenges Crowler to a Duel , and the latter accepts , with him promising to allow everyone to graduate should Jaden defeat him . Jaden Summons " Elemental Hero Flame Wingman " in his first turn . Crowler expects this , and removes from play " Flame Wingman " using his " Unfinished Time Box " Trap Card when " Flame Wingman " destroys his " Ancient Gear Soldier " . He then successfully Summons 3 " Ancient Gear Golems " and reduces Jaden ' s Life Points to 200 , thanks to their Piercing effects . Jaden comments that Crowler is a great teacher , and thanks him for showing him such an awesome combo . He strikes back using " Elemental Hero Flare Neos " and " Instant Neo Space " . At this point , Crowler breaks down crying , and reveals that he doesn ' t want the seniors to graduate as he will miss them . Many of the students even begin cheering for Crowler , telling him not to give up . Crowler unveils his most powerful monster - " Ultimate Ancient Gear Golem " , with an attack of 4400 . Despite being reduced 100 Life Points , Jaden still appears optimistic , and Crowler himself wishes to see how Jaden will turn the situation around and defeat him . Jaden shows him just that , by freeing his " Flame Wingman " from " Unfinished Time Box " with a combination of " Elemental Hero Air Neos " and " Cyclone Wing " . He activates " Demise of the Land " , which lets him activate " Skyscraper " in the middle of his Battle Phase , and destroying Crowler ' s " Ancient Gear Golem " with " Elemental Hero Flame Wingman " , winning this Duel the same way he won their first Duel . Crowler comments that he ' s learned just as many things from his students as they ' ve hopefully learned from him . He realizes that he need to move forward as a teacher , much like the graduates . With this , Crowler begins teaching classes again , but forces Jaden to do all the work he ' s missed in his skipped classes . Featured Duel : Jaden Yuki vs . Vellian Crowler .

" Flame Wingman " attacks and destroys " Ancient Gear Soldier " . Since " Flame Wingman " destroyed a monster by battle and sent it to the Graveyard , Crowler takes damage equal to his destroyed monster ' s ATK ( Crowler 4000 → 2700 ) .

Jaden then activates " Instant Neo Space " and equips it to " Flare Neos " . Now " Flare Neos " does not have to return to Jaden ' s Fusion Deck during the End Phase due to its own effect . Due to the effect of " Flare Neos " , it gains 400 ATK for each Spell and Trap Card on the field and there are currently three ( " Flare Neos " : 2500 → 3700 / 2000 ) .

" Ultimate Ancient Gear Golem " attacks " Flare Neos " , but Jaden removes from play " Necro Gardna " from his Graveyard via its own effect to negate the attack . Crowler activates his face - down " Desperate Battle " to reduce the ATK of " Ultimate Ancient Gear Golem " by 1000 ( " Ultimate Ancient Gear Golem " : 4400 → 3400 / 3400 ) and allow it to attack again ( " Flare Neos " : 3700 → 3300 / 2000 ) . " Ultimate Ancient Gear Golem " attacks and destroys " Flare Neos " ( Jaden 200 → 100 ) . The last effect of " Instant Neo Space " then activates , letting Jaden Special Summon " Elemental Hero Neos " ( 2500 / 2000 ) from his Deck in Attack Position . On Crowler ' s End Phase , the effect of " Desperate Battle " expires ( " Ultimate Ancient Gear Golem " : 3400 → 4400 / 3400 ) . Turn 6 : Jaden Jaden draws " Demise of the Land " . During Jaden ' s Standby Phase , he removes from play " Take Over Five " from his Graveyard in order to draw a card ( " Fifth Hope " ) .

He then Contact Fuses " Neos " with " Air Hummingbird " in order to Special Summon " Elemental Hero Air Neos " ( 2500 / 2000 ) in Attack Position . Since Jaden ' s Life Points are lower than Crowler ' s , " Air Neos " gains ATK equal to the difference due to its own effect ( " Elemental HERO Air Neos " : 2500 → 4400 / 2000 ) . Jaden then activates " Cyclone Wing " and equips it to " Air Neos " . Now when " Air Neos " attacks , one Spell / Trap on the opponent ' s side of the field can be destroyed . " Air Neos " attacks " Ultimate Ancient Gear Golem " . Jaden activates the effect of " Cyclone Wing " to destroy " Unfinished Time Box " . The final effect of " Unfinished Time Box " then activates , returning " Elemental Hero Flame Wingman " ( 2100 / 1200 ) to Jaden ' s side of the field in Attack Position . " Air Neos " and " Ultimate Ancient Gear Golem " then destroy each other in a Double KO . Crowler then activates the final effect of " Ultimate Ancient Gear Golem " to Special Summon " Ancient Gear Golem " ( 3000 / 3000 ) from his Graveyard in Attack Position , ignoring the Summoning conditions . Jaden activates " Demise of the Land " to activate " Skyscraper " from his Deck . Now if an Elemental Hero attacks , it will gain 1000 ATK during damage calculation only . " Flame Wingman " attacks " Ancient Gear Golem " . The effect of " Skyscraper " activates ( " Flame Wingman " : 2100 → 3100 / 1200 ) .
