Nightshroud states that the will of a single human cannot change the logic of the world and that Jaden has no chance of defeating him . He Summons the " Darkness Seed " in his Graveyard which has the ability to return his Life Points to 4000 during at the end of each turn and cannot be destroyed by battle . Nightshroud states that his " true identity " is " humanity ' s future " . He states that the abnormal weather , endless wars and terrorism make it inevitable that the world will become nothing but a desolate wasteland . Nightshroud Tribute s " Darkness Seed " to Summon " Darkness Bramble " , which has the effects of both " Darkness Seed " and " Darkness Eye " . Able to confirm his Set cards again , he activates " Zero " , " Infinity " and " Darkness 3 " to inflict 3000 damage to Jaden . As Jaden begins his turn , Nightshroud activates the combo again , which would deal 2000 damage and defeat Jaden , but Jaden but chains " Quick Summon " to Special Summon " Chrysalis Pantail " , Tributing it with " Cocoon Veil " to negate the damage and Summon " Neo - Spacian Dark Panther " . Jaden attacks with " Neos Wiseman " but Nightshroud discards " Darkness Raincrow " and Tributes " Darkness Bramble " to Special Summon the 4000 ATK " Darkness Neosphere " which also retains the effects of " Darkness Bramble " and lets him rearrange his Set cards in any order he chooses . Jaden counters by copying " Darkness Neosphere " with " Dark Panther " , rearranging Nightshroud ' s Traps again and re - setting " Darkness " . Should Nightshroud choose to activate " Darkness " again , its effect will destroy all of his Spells and Traps . Though Nightshroud can no longer use his " Zero " and " Infinity " combo , he still has the high ATK of his " Darkness Neosphere " . Nightshroud then destroys " Neos Wiseman " with " Darkness Neosphere " . Yubel urges Jaden to to use the effect of " Neos Wiseman " to remove her card from play to Special Summon " Elemental Hero Neos " . Nightshroud reiterates that it is hopeless and that Jaden should surrender - he is alone and no one else can fight . Jaden tells him that he ' s wrong , stating that he ' s not the strong one . His soul was once drowned in darkness and he hurt many of his friends - but that taught him something - to believe in the power of friendship and the strength of one ' s cards . Jaden calls out to his friends trapped in the World of Darkness , telling them to fight back by believing in the power of one card and to remember the people they have fought using it . Jaden himself remembers the opponents he fought with " Neos " at his side . His voice reaches them and the scenes where each of them is engulfed by the waves of darkness is replayed but this time they hold up a single card - " Ojama Yellow " for Chazz , " Power Bond " for Syrus " and " Doble Passe " for Alexis . They each accept their futures and know they can struggle their way back up again . This allows them to escape from the World of Darkness and all of the people trapped do the same . Duel Academy ' s students are back and they all appear behind him while watching the remainder of the Duel . Jaden draws " Polymerization " and thanks his Deck for all the bonds it brought him . He activates his face - down " Hope for the Future " , which lets him discard " Polymerization " to send from his Deck to the Graveyard the Fusion Material Monsters for a " Neos " Fusion Monster . He sends " Neo - Spacian Air Hummingbird " , " Neo - Spacian Aqua Dolphin " , " Neo - Spacian Flare Scarab " , " Neo - Spacian Grand Mole " and " Neo - Spacian Glow Moss " from his Deck to the Graveyard . Then , he performs an " Ultimate Contact Fusion " , returning the six " Neo - Spacians " and " Neos " on his field and in his Graveyard to his Deck to Fusion Summon " Elemental Hero Divine Neos " . He uses its effect , removing the " Neo - Spacians " in his Deck from play to gain ATK and having it inherit the power of " Neo - Spacian Flare Scarab " to increase its attack further . He attacks and wipes out Nightshroud ' s Life Points . His hood is blown over in the strike and his true face is revealed - that of a skeletal goat - like creature . He states that even with his defeat he will return as long as darkness exists in the souls of humans . Jaden counters by saying that as long as Duelists believe in their futures , he ' ll never come back . Nightshroud is enveloped in light and is destroyed along with the World of Darkness . Due to this , the shadows fade away and the sun becomes visible in the sky . Featured Duel : Jaden Yuki vs . Nightshroud . " Duel continues from the previous episode " .
