This has been bugging me for quite some time, but... what happened to Dr. Ziggurat after his Spiral Force was destroyed? After he lost to Zeo and his bey, Spiral Capricorn hit the ground, that was his last (physical) appearance on the show. What happened to him after the events of Beyblade: Metal Masters?
