It first aired in Japan on January 31 , 2007 and in the US on September 29 , 2007 . Summary . Adrian Gecko reaches Marcel Bonaparte and questions the demon who possessed Marcel why it chose him instead of Adrian . It responds that Marcel had a greater darkness in his heart than Adrian , but offers to make Adrian a deal , as it needs his help . In the gym , Ms . Dorothy begins to hand out rations to the assembled students . Each get only one roll and a small bottle of water , as they have only a week ' s worth of each and only if they ration it carefully . At the infirmary , Blair Flannigan is resting , though her condition is worsening . Bastion Misawa reveals that as he was walking in the desert , he spotted a submarine that must have been transported here along with Duel Academy . Bastion suggests that there might be medicine in the sub that could save Blair , so they organize a team to journey into the desert to get to it . Vice - Chancellor Bonaparte gives them permission to leave and Jaden Yuki , Jesse Anderson , Jim Crocodile Cook , Axel Brodie and Adrian Gecko venture out . Adrian catches up to them just before they leave , as he needs to delete any information aboard the submarine that could reveal his true intentions . As the Bio - Band s are still functioning , they agree to only summon monsters if attacked . They are attacked almost immediately by a Sand Stone , but avoid summoning any monsters . Due to their interference , Marcel uses a " The Rock Spirit " card to materialize its spirit , Titan to attack them . Jesse agrees to be his opponent , as Jaden and Axel slip into a crater and Jim and Adrian are occupied holding them by a rope to stop them from slipping any further . Due to the desert , the field is treated as being " Wasteland " , so this unlocks abilities that the desert monsters wouldn ' t otherwise have . This causes havoc for Jesse , and they learn that in the desert life points are also real . Ultimately though Jesse wins the duel . They reach the submarine . Jesse locates the medicine , Jaden gathers food , and Jim obtains a large pile of blankets to take back with them . Axel finds some torpedo holes but decides they have little use . Adrian reaches a computer console and deletes all the information stored in the sub . Marcel uses another " The Rock Spirit " card , and this time Titan materializes on top of the sub , and sends a pack of " Fiend Scorpions " in . With the scorpions blocking the only exit , Jaden summons " Elemental Hero Clayman " to block the scorpions path while they retreat . Titan uses a combination of " 8 - Claws Scorpion " and " Book of Moon " to destroy " Clayman " . Jesse steps in , and states that he ' s already lost energy , so he ' ll duel so that everyone else will be able to maintain their own strength . " Crystal Beast Topaz Tiger " and " Crystal Beast Amethyst Cat " destroy the scorpions and Titan summons " Sand Doodlebug " in response . It causes the submarine begin to sink into a whirlpool of sand . They all run , but are forced in the opposite direction towards the torpedoes . Jaden sends " Elemental Hero Grand Neos " through one of the sub ' s torpedo tubes , and has it pick the sub and throw it on top of Titan , killing him . Jaden is pleased by the way his plan worked out , whilst the others , Jesse in particular , aren ' t impressed as the jolt of he submarine has caused them all to land on top of each other , Jaden landing apparently unharmed on top of Jesse . Finally they start to trek back to Duel Academy . Featured Duel : Jesse Anderson vs . Titan , the Rock Spirit .
