The Quest for Xerneas

This is the scene, where our heroes, began searching to find Xerneas in Team Robot in Pokemon: Diancie & The Cocoon of Destruction

(Later our heroes began to search for Xerneas)

Seismo: That's a strange forest here.

Ash Ketchum: So this is the Allearth Forest.

Clemont: It's hard to believe this entire area was destroyed.

Daggett: Like a disaster in California.

(We View a Scatterbug who was sitting in a tree and Serveal Spritzee Arrived)

Dace: After many years, this ruined forest has come back to life.

(We See Combee, Oddish, Foongus, Amoonguss, Skiddo, Zigzagoon, Linoone and Gogoat)

Dace: Some even say that Yveltal caused the forest's destruction in order to awaken and invigorate the forest's vitality.

(Sandshrew. Sandslash and Starly appears)

Rigby: I think something has told, where to see Xerneas.

Clemont: I guess it's possible that such total destruction could be a part of the balance of nature.

Ash Ketchum: The balance of nature?

Mordecai: What is the balance of nature?

Clemont: You could say that it's like a rule, A rule that governs both life and destruction.

(Meanwhile Team Rocket are on the Hot Air Balloon)

James: Word has it this forest is forbidden to enter.

Meowth: Yeah, but forbidden or not, Diancie's somewhere down there.

Jessie: Right. After coming this far, there's no turning back.
