A Towering Takeover!

The Kalos League award ceremony is interrupted as giant creeping vines engulf the stadium and threaten to take over Lumiose City! Lysandre broadcasts Team Flare’s manifesto: they want to create a new world order, where only the “chosen ones” will join them.
Ash and Alain set off to rescue Mairin, but Ash is shocked to discover that Alain has been working with Lysandre, and Team Flare imprisons Ash atop Prism Tower. His friends try to help, but an angry Zygarde stands in their way—until it’s confronted by a second Zygarde, as Squishy transforms and reveals its true identity! A showdown is imminent, and it’s Zygarde vs. Zygarde!
