During this, Luna sat back and watched "[[Ancient Fairy Dragon (manga)|Ancient Fairy Dragon]]" and "[[Power Tool Mecha Dragon]]" assault him, with the force of their [[Feel]] destroying his [[Duel Runner]] whilst Luna claimed that Aria was weak and boring. During the attack, one of "Power Tool Mecha Dragon's" screwdriver missles almost killed two innocent by-standers, but they were protected by [[Crow Hogan (manga)|Crow Hogan]] and his "[[Blackwing Tamer - Hawk Joe]]".
