Arus Forest.
The sky was veiled in grayish red.
Deep within Arus Forest, the river had turned purplish red, and blood-red mist filled the air.
The Pokémon that lived there sensed the destructive presence within the black mist and fled.
The sole exception was the enormous cocoon,
which slowly rose from the pond in the basin-Yveltal!
In stark contrast to the fleeing wild Pokémon, Li Wei and the others rode Arcanine and Metagross toward Yveltal.
They swept past the vibrant outskirts of the forest and resolutely followed Xerneas across the line of death.
At the forest's edge, when they saw Li Wei and the others cross the line of death under Xerneas's guidance,
Bunnelby, Oddish, Linoone, Gogoat, and the other Pokémon stopped in their tracks.
By the time Li Wei, Xerneas, and the others reached the depths of Arus Forest, Yveltal had fully awakened.
A purple beam gathered in Yveltal's mouth, and everything in its path turned to stone!
That was Yveltal's move, Death Wing!
Anything struck by Death Wing would have all its life energy drained away, whether human or Pokémon.
By the time Li Wei and the others arrived, Yveltal had already fired several consecutive Death Wings, ravaging the land.
Nobody had bothered it, so why was it so furious?!
What Li Wei did not know was that, before they reached the forest's depths, Yveltal had already blasted whoever disturbed it with a Death Wing.

Steven immediately pulled the Mega Brooch from his chest. "Metagross, Mega Evolution!"

Its black-and-red wings spread abruptly, and terrifying destructive energy rapidly gathered in its throat, forming a searing beam of darkness.
Death Wing was ready to fire!
If that attack
