Raviel , Lord of Phantasms ( character ) Raviel , Lord of Phantasms is a character version of the card , " Raviel , Lord of Phantasms " . Character design . The designs of the Sacred Beasts , " Raviel " was overseen by Kenichi Hara . Each of them resembles one of the three Egyptian God Cards ; " Raviel , Lord of Phantasms " finds a counterpart in " Obelisk the Tormentor " . Unlike the God Cards , however , they possess certain visual cues that make them distinct from their predecessors , including translucent wings and more pronounced claws and skeletal features . Yu - Gi - Oh ! GX . In Yu - Gi - Oh ! GX , the Sacred Beast s are legendary creatures whose cards were sealed by Kagemaru underneath Duel Academy behind the Spirit Gates , which requires seven Spirit Keys to open , as he could not unlock their power at the time . Should they ever be set free from their stronghold , chaos and darkness will envelop the world , destroying everything . The Shadow Riders sought to acquire the Spirit Keys and revive the Sacred Beasts . In order to open the gate , a strong dueling presence is required ; if the keys are stolen and placed in the gate , ( as attempted by Don Zaloog ) for example , nothing will occur . To meet the challenge of the Shadow Riders , seven of Duel Academy ' s finest duelists were selected , these duelists were Jaden Yuki , Zane Truesdale , Chazz Princeton , Alexis Rhodes , Bastion Misawa , Lyman Banner ( the only Shadow Rider to get his key by default , due to the fact his true identity was unknown at the time ) and Vellian Crowler , and although the Shadow Riders were defeated , Kagemaru managed to awaken the Sacred Beasts because of the dueling energy released from the duels . In exchange for freeing them from imprisonment , the Sacred Beasts slowly returned Kagemaru to a youthful state , empowering him with the energy sapped from Duel Monster spirits , but Jaden Yuki ' s interference resulted in the man ' s downfall . They were thus locked away once more . After Duel Academy is transported to an alternate dimension in the third season , a Yubel - possessed Marcel Bonaparte retrieves the Sacred Beasts and builds a Deck around them , which boosts the Summoning speed of the Sacred Beasts and also supports the Summoning of their combined form , " Chaos Phantasm Armityle " . When Jesse Anderson was possessed by Yubel he reappears after having been missing for episode 131 to 147 , he uses them in a Deck based around quickly Summoning the Beasts and " Armityle " . Although Yubel didn ' t use them in her final Duel with Jaden , " Raviel " was shown to be in her Deck . What happened to them after Yubel merged with Jaden is currently unknown , although it is likely that Jaden returned them to their resting place . Non - canon appearances .
