Xerneas and Yveltal both debuted ''[[M17|Diancie and the Cocoon of Destruction]]'' as major characters. In the {{pkmn|movie}}, Diancie had a responsibility as the Princess of the [[Diamond Domain]] to maintain the balance of its ecosystem by making a new Heart Diamond. However, as she lacked the power to create a stable Heart Diamond, she sought help from Xerneas, as its Fairy Aura could revitalize energy. As Diancie's journey began, she bumped into {{Ash}} and {{ashfr}}, who soon decided to accompany Diancie in her pursuit of Xerneas. As the team pursued the Legendary Pokémon, several thieves—[[Merilyn]], [[Riot]], [[Argus Steel]] and [[Millis Steel]]—were also in pursuit of Diancie to take advantage of her ability to create diamonds. The group were able to catch a moment with Xerneas and bathed under its Fairy Aura, as Xerneas told Diancie that Fairy Aura was not what she needed, but there was a power inside her. The chase led to [[Allearth Forest]] and the group's activity awakened and enraged the Cocoon of Destruction, Yveltal. Yveltal went on a rampage with its {{m|Oblivion Wing}}, petrifying the thieves and their Pokémon. Yveltal eventually gained on the group, continually firing harmful beams that triggered extreme emotions within Diancie, enabling her to [[Mega Evolution|Mega Evolve]]. Before [[Ash's Pikachu]] was completely petrified by Yveltal, Xerneas appeared to battle it, and its mere presence was able to quell Yveltal's rage. Yveltal finally flew calmly away from the forest. Soon after, Xerneas used its Fairy Aura to revitalize the forest and revive the Pokémon and people petrified, including Pikachu. Xerneas then transformed into its dormant form to look over Allearth Forest for the next thousand years.
