Yu - Gi - Oh ! 5D ' s - Episode 104 " Knight Takes Pawn " , known as " Envoy of Destruction , Team Catastrophe " in the Japanese version , is the one hundred and fourth episode of the " Yu - Gi - Oh ! 5D ' s " anime . It first aired in Japan on April 7 , 2010 and in the United States on May 7 , 2011 . In the Japanese version , the opening and ending themes are changed from " FREEDOM " and " - OZONE - " to " BELIEVE IN NEXUS " and " Close to you " respectively , starting with this episode . Summary . Team 5D ' s next opponent is Team Catastrophe , who has made every one of their opponents crash , including Team Unicorn . Wondering about this , Yusei and his friends search for what could have caused these crashes . Breo supplies data from Andre ' s and Jean ' s Duel Runner s , and Bruno analyzes it , finding that they both experienced a rapid change in their functionality during their Duels . His diagnosis is that both Duel Runners crashed because their rear wheels jammed . When Crow hears this , he says that just before Blackbird crashed , the wheel felt weird , and he agrees with the idea of a jammed wheel . But that still doesn ' t answer what would cause the same malfunction three times over . Just then , Carly brings out a tape she made of Team Unicorn ' s Duel with Team Catastrophe — for which Jack scolds her for not mentioning such a valuable clue earlier . They watch it , slowing it down just before each of the crashes . Nobody can see anything unusual about the Duel Runners , but Yusei notices something else : just before each crash , the same monster was on Team Catastrophe ' s field . Bruno locates its name : " Hook the Hidden Knight " . It ' s a start to their answer , and since Team 5D ' s will be Dueling Team Catastrophe next , they have to be ready . This raises the question of what their opponents ' next move might be . With a shock , they realize one of them isn ' t there . Out on the highway , Akiza is working hard to practice for her next round . As she passes under a bridge with three people on it , her Duel Runner locks up , and she is thrown from the crash . Just before going airborne , she Summons " Rose Tentacles " , but as it moves its vines to catch her , she passes right through them . Helplessly , she realizes her psychic powers are not working , which is her last thought before she hits the pavement . The others find her already being taken to the hospital . She is unconscious and in a critical state . To avenge Akiza , Crow shrugs off his injured shoulder , determining that he will participate . The next day , Team 5D ' s and Team Catastrophe square off for their battle . Team Catastrophe is somewhat surprised to see Crow not only bent on fighting them , but also presenting himself as the first wheeler . ( They address him with the Japanese descriptor of one who has just been released from the hospital . ) The first round will be between Crow and Hermann , and Hermann takes the first turn , summoning " Hook the Hidden Knight " . This fills Team 5D ' s with foreboding , but Crow faces it , even though so much as drawing a card shoots pain through his arm . His first attack , however , is neatly blocked by a hazardous effect . But he isn ' t worried about that . What does get his attention is his Duel Runner ' s shadow in the bright sun . . . a shadow from which a hook has just risen , reaching for his rear wheel . With no time to think , Crow steers away , keeping his balance . But Team Catastrophe is just warming up , and Team 5D ' s is only just now realizing that the danger may be even greater than they guessed . Featured Duel : Crow Hogan vs . Hermann .
