This Y exclusive Legendary spreads its portentous wings before draining the life from any creature in its presence, human and Pokémon alike. It reverts to the form of a tree in the forest created from this energy awaiting Yveltal's next arrival. It emerges to wash a convalescent light over the land from its horns and renew the life Yveltal has stolen. Xerneas can only be caught in X and is a symbol of eternal life. It's only level 50 and isn't very hard to catch, so you could choose to save the Master Ball for something more fickle. It would be a good idea to save beforehand. After clearing the room, you may awaken the Legendary Pokémon who will attack you. Inside the energy room, you have to battle 4 Team Flare Admins, totalling 6 Pokémon between them. You'll eventually come to a door that leads into the room where the Legendary is being drained of energy.
LITTLE ICEBERG POKEMON SERIES
You engage in a series of three double battles here with Rival. Next, run to the door to the left and down the hall. Hop into the portal, fight the grunt, and run all the way left to a room where Mable from the Ice Cavern is. Again take the right arrow down to a green portal. Use the one on the right and you find yourself at two more. On the other side of that is a female grunt standing above three arrows pointing down. To the right of the female Grunt is an arrow pointing east you need to take that throws you to another arrow pointing right. You'll need to run up past two Grunts standing in the way to the key. Leave the room and step on the first blue arrow east and then the one pointing down just below that. Sina and Dexio are there in their luchador gear looking for the large man you saw much earlier and give you some revives. Spin up the room north and go through the door at the top. There, battle Aliena from the Power Plant to pass and take the left portal. Start by going left and battle the first Grunt to get to the green teleport. Much like the Ice Cavern, you won't stop spinning until you hit a wall. In order to get around on this floor you need to walk across the blue arrows and spun in the direction they indicate.

When you win, he disappears through the elevator and you need the key card to use it.
