Yu - Gi - Oh ! GX - Episode 044 The Seventh Shadow Rider , known as The Shadow of the Seventh in the Japanese version , is the forty - fourth episode of the " Yu - Gi - Oh ! GX " anime . Summary . Jaden Yuki , Syrus Truesdale and Chumley Huffington have overslept , and rush to the meal hall to eat . They find that most of their food is gone , and Chazz Princeton confirms that he ate it himself . They call for Professor Banner , but he ' s disappeared . They later sit in Banner ' s alchemy class , and Chumley comments that most of the staff is using their spare time to search for Banner . Dr . Crowler enters the room , and reveals he ' ll be substituting for Banner today . Crowler begins the lecture on " the mark of Amnael " , but cannot understand alchemy and ultimately blows a lab experiment up in his own face . He informs the Jaden , Chazz , Alexis Rhodes and Bastion Misawa to report to Chancellor Sheppard ' s office after the class is over , and he and Zane Truesdale join them there . Sheppard informs him that they can find no trace of Banner , and there is no indication he has left the island either . Chazz determines that he must have lost to a Shadow Rider , but Sheppard responds that another Spirit Gate has not opened , which means Banner ' s Spirit Key is still safe , so he should be as well . Jaden meets with Syrus and Chumley and wants to keep searching for Banner , but does not know where to begin . Chazz arrives and again has delusions of being a great detective , and leads them off to search . He states that they must journey to the " scene of the crime " , with Syrus commenting that that ' s the problem - they don ' t where that is . Chazz responds that it was a figure of speech . They check Banner ' s room at the Slifer Red dorm and find a note . Chazz determines that the seventh Shadow Rider was Ms . Dorothy and that she must have defeated Banner . This turns out to be completely wrong . They continue to search for clues , and they eventually find a map with the Mark of Amnael on it , and they determine that it ' s location must be where Banner is . They begin to walk to said location , and they plan to lure Pharaoh to them . A masked , cloaked figure watches them from a tree branch . Alexis returns to the Obelisk Blue to find her brother ' s room ransacked . The mark of Amnael appears , and she follows it outside , and begins to chase the same man that watched the others from the treetops . He stops running , and eventually she catches up . Assuming he ' s a Shadow Rider , she challenges him to a Duel . She uses " Polymerization " to fuse " Etoile Cyber " with " Blade Skater " to Fusion Summon " Cyber Blader " . She attacks , but her opponent activate s a Trap which blocks her monster ' s attack , though what Trap it was is not shown . Her opponent plays a card which appears to cause a meteor strike , which destroys her " Cyber Blader " . He attacks directly with two monsters shrouded in shadow , and Alexis is defeated . She drops to the ground , and her opponent claims her key . He opens a book with The Eye of Wdjat on the cover , which appears to absorb Alexis into it . That night , Jaden , Syrus , Chumley and Chazz gather around a campfire . They later resume their search , and believe they hear Pharaoh , so they split up to search . Chazz finds Pharaoh as well as Banner ' s eyeglasses . The mark of Amnael appears , and he follows it , which leads him past all of Banner ' s dropped clothes . The same cloaked man from before appears , and they begin their Duel . Chumley finds Pharaoh , and Jaden ' s own Shadow Charm activates . Back at the Duel , Chazz has only 800 Life Points left , but has " Armed Dragon LV7 " on the field . He discard s " Despair from the Dark " to destroy his opponent ' s mons ters via the effect of " Armed Dragon LV7 " . His opponent Summons a golem - like creature , and then plays the same meteor strike card as in his Duel with Alexis ; the two wipe out Chazz ' s field . He attacks directly . The others find Chazz ' s cards scattered in the water nearby sometime later . The cloaked man goes to the Spirit Gates , and places three more keys into it , leaving Jaden ' s as the only remaining key . Six pillars of rainbow light burst from the waters around Duel Academy .
