Yu - Gi - Oh ! GX - Episode 107 " A Jewel of A Duel : Part 2 " , known as " Neo - Spacians VS Gem Beasts " in the Japanese version , is the one hundred and seventh episode of the " Yu - Gi - Oh ! GX " anime . It first aired in Japan on October 18 , 2006 , and in the US on April 21 , 2007 . Summary . The exhibition match between Jaden and Jesse Anderson continues . Meanwhile , Thelonious Viper is still at the lab where Wheeler was worked on . He is seen several times laughing at the - like object he brought with him . Eventually , he ends up back at Duel Academy watching the Duel , and comments that he hopes that this Duel will inspire other students . Chancellor Sheppard concurs . Viper privately thinks to himself that he wants Jaden and Jesse to continue their fight , so he can extract their " Duel Energy " to make his dream a reality . As he thinks this , the screen cuts back to the lava lamp , in which opens a single eye . A voice says that it will see Jaden soon ( in the dub , it says it wishes to " play " with Jaden , while in the Japanese , the voice calls him " my precious Judai " ) . During the Duel , Aster appears behind Jaden ' s friends in the audience . When questioned what he ' s doing here , he reminds everyone he ' s still technically a student at Duel Academy , despite also competing in the Pro League . Aster comments that Jaden has never faced an opponent like Jesse before - since they both believe of the powerful bond between Duelist and Deck . Aster says he once personally spoke with Maximillion Pegasus , after having won an Industrial Illusions - sponsored tournament . Pegasus revealed that Aster was his fourth - favorite Duelist - the first three being Yugi Muto , Seto Kaiba and Joey Wheeler , respectively . When questioned about the fifth , Pegasus reveals it to be Jesse . He states that Jesse had participated a Southern ( European in the Japanese version ) tournament , and while there , the " Crystal Beast " cards Pegasus had taken with him began to glow . He took this as a sign that the cards had chosen Jesse , and thus gave them to him . Both Jesse and Jaden get a little carried away during the Duel , both being reminded during the Duel to focus on the battle and not on being impressed by their opponent ' s cards . Jaden ultimately wins the Duel , but Jesse pretends to Summon his signature card , " Rainbow Dragon " , but reveals that he doesn ' t actually have it . Pegasus won ' t create the card until the tablet where the seven gemstones from Rome would have been placed is found . This causes quite a row and Jaden is left disappointed . Jesse doesn ' t seem to notice as he asks all the other students to keep an eye open for the tablet . Thelonious Viper approaches them and congratulates on an excellent Duel . He states that this year , he will institute Survival Duels between students , as he values practical Dueling over lessons . On Duel Academy ' s roof , Jaden and Jesse sit and discuss their Duel , both offering advice to the other on alternate moves they could have made . Syrus , Hassleberry , Chazz and Aster watch them , Aster then explaining he ' s going back to the pro leagues since Jaden ' s found himself a twin ( In the dub he reminds them it could be worse and at least Chazz doesn ' t have a twin ) .
