An Explosive Operation

In search of Team Flare and Squishy, Team Rocket meets a similar-looking Pokemon, known as Z2...and Team Flare is right behind it! The two teams battle back and forth, and Z2 changes hands several times—until it merges with many Cells to become a menacing serpentine Pokemon who shakes the land with its attack!
Z2 is winning, but Lysandre has called for backup! With the help of Alain and his Mega Charizard, Team Flare battles Z2 to a standstill and locks it in a cage, where Lysandre finally reveals its name—Zygarde!
Meanwhile, at our heroes’ campsite, Bonnie cuddles a sad and worried Squishy, trying to figure out what’s wrong...
