Zygarde

X / Omega Ruby: When the Kalos region’s ecosystem falls into disarray, it appears and reveals its secret power.

Y / Alpha Sapphire: It’s hypothesized that it’s monitoring those who destroy the ecosystem from deep in the cave where it lives.

Sun: This is Zygarde’s form when it has gathered 50% of its cells. It wipes out all those who oppose it, showing not a shred of mercy.

Moon: It’s thought to be monitoring the ecosystem. There are rumors that even greater power lies hidden within it.

Ultra Sun: This is Zygarde’s form when about half of its pieces have been assembled. It plays the role of monitoring the ecosystem.

Ultra Moon: Some say it can change to an even more powerful form when battling those who threaten the ecosystem.
