Yu - Gi - Oh ! 5D ' s - Episode 105 " Rook Takes Knight " , known as " The Dark Card , Hidden Knight - Hook - " in the Japanese version , is the one - hundred - and - fifth episode of Yu - Gi - Oh ! 5D ' s . Summary . The second round of the WRGP commences with the duel between Team Catastrophe and Team 5D ' s . Hermann of Team Catastrophe uses " Hook the Hidden Knight " , which has a shadow effect where , every time the monster attacks or deals damage by its effect , a phantom shadow of the monster tries to physically destroy the tires on Crow ' s Duel Runner with its hooks . Knowing that his injuries make it painful to ride , Team 5Ds calls Crow back to the pit , but he refuses and pushes on . Having already dodged one of the phantom ' s attacks , Crow relies on his steering reflexes to dodge " Hook the Hidden Knight " while trying to come up with a strategy to destroy it . Each dodge frustrates Team Catastrophe further , even pushing Crow to rely on Blackbird ' s flight mode as their monster becomes more bold . In the process , Hermann reveals that " Hook the Hidden Knight " is a Card of Darkness , surprising everyone when they realize that the monster is more than just a Solid Vision projection . Although the strain and shock from swerving are aggravating Crow ' s injuries , he refuses to give in , even ignoring his team ' s sign to return to the pit until he ' s destroyed " Hook the Hidden Knight " . He attacks over and over , culminating in a strike from " Black - Winged Dragon " , overwhelming Hermann ' s defenses and Life Points as " Hook the Hidden Knight " is finally destroyed . Hermann declares that his shadow monster is not so easily destroyed , but his attempt to revive " Hook " for his teammates is countered by Crow , who sacrifices his own dragon to ensure that the monster is gone for good . With his injuries acting up , Crow finally returns to the pit , with Jack taking his place . On the other side of the field , Nicolas takes the baton from Hermann , vowing to destroy Team 5D ' s with his " other " secret weapon . . . As the second round of the Duel commences , Nicolas sets one card face - down and ends his turn . Jack summons " Power Giant " for a direct attack , but Nicolas counters with a trap called " Doom Ray " , which inflicts 800 Life Points of damage for each card in the user ' s hand to both players . Leo and Luna realize that Nicolas has 5 cards , so his Trap will inflict 4000 damage - enough to defeat both Jack and himself in one shot ! Nicolas cackles that " Hook the Hidden Knight " wasn ' t his team ' s only shadow card - Team 5D ' s members realize that " Doom Ray " will inflict real damage , too . The Trap finally activates , filling the field with a large explosion . Within the explosion , shrieking purple souls swarm around both riders . Nicolas gloats that Jack ' s Duel Runner is doomed , but he suddenly realizes that he is being affected by the real damage , too . Watching the Duel from above , Primo sneers that Team Catastrophe has outlived its usefulness . But Jack is unfazed , as the effect of " Power Giant " prevents Jack from taking any effect damage when he attacks with it . A Duel Runner flies from the explosion and crashes spectacularly , with Team 5D ' s and their friends thinking it was Jack . But then , Jack ' s Runner emerges from the flames , with Nicolas clinging to the side . Because Nicolas ' s Duel Runner was destroyed , therefore preventing him from returning to the pit to tag Hans into the match , his team loses by default - Team 5D ' s is off to the finals ! Nicholas asks Jack why he saved him ; Jack answers that Nicholas is unworthy of death and duelling alike because he uses cards of darkness instead of believing in his own cards . As Jack drives off , Sherry approaches Nicholas , asking where he got the " Doom Ray " card . She takes his Deck and looks at the card , but its name , effect and image suddenly disappear . Above the stadium , Lester mockingly asks Primo why things never seem to go his way , but the other member of the Three Pure Nobles has vanished . Elsewhere in the city , a large garage opens , releasing legions of Riding - Roids onto the highway . From atop a tall building , Primo issues his orders to the Riding - Roids , calling them " Diablo " . Featured Duels . Crow Hogan vs . Hermann . Turn 2 : Crow Crow sets four cards .
