Yu-Gi-Oh! GX - Season 1 Episode 57
The Demon

Jaden and Bastion are still Duel Academy students, so they have to practice a lot. Bastion uses his WaterDragon again, but Water Dragon can not defeat Jadens ShiningFlareWingman. Before dueling against Zane, Aster talks to his manager about the future and his victory. Jaden is extremely surprised, when he sees Avians appearance on Asters field. During next turn, Aster fuses Avian with Burstnatrix, but instead of FlameWingman, Aster creates PhoenixEnforcer which impresses Jaden and Syrus. But the best thing in PhoenixGuy is that he can not be destroyed in battle. And thanks to that special ability, Aster defeats Zane, by fusing PhoenixEnforcer with Sparkman to summon ShiningPhoenixEnforcer and using DestructionOfDestiny to send 4 more ElementalHeroes to the graveyard and raise ShiningPhoenixGuys attack to 4900.
