For Fun: How would you beat Decade Fury Form?

[Emperor IXA]

just send Decade to 00 (S2) World and get Setsuna & Saji to use TRANS AM to take Decade away from earth and either (a) just dump Decade in space
(b) Raiser Sword Decade's @$$

Summon Dark Kiva, send Decade to a post-apocalyptic wasteland world, and then make DK perform the King's World End (Wake Up Three) on the enemy.
