Perfect Siege

&nbsp When Shun became the head of the Gundalian Castle Knights, he got a new bakugan for his master: Perfect Siege. While Drago lost the perfect core, Perfect Siege gained a part of it. Kazarina used a bit of the perfect core to make a siege stronger and now Perfect Siege can access all six attributes. Only the real Shun uses this bakugan, the other members of the Gundalian Castle Knights use normal sieges.
