(In that case...) Heal Pulse!! Gardevoir announced as he formed a rainbow
sphere of light around himself, sending a ring of light outward. It
hit Servine, the air around whom began to shimmer and glow light
colors.
"Arceus, I'm the Legendary Pokémon of order between life and death.
Please, give me a valid reason - WHY do I not know how to revive
dead Pokémon?" Zygarde asked the sky - or, rather, the roof of the
cave.
(Arceus is such a friendly guy, making someone mute for breaking a
"law" that nobody but he and the Unown knew existed and not
answering Zygarde's question until he gets to witness the suffering
of said mute Pokémon. I would totally want to be his friend is real
life. [If you haven't noticed, that was sarcasm.])
Gardevoir teleported back a while later with a huge pile of Pecha,
Rawst, and Sitrus Berries.
Is she okay? I brought her berri- why are you crying?
Gardevoir asked fearfully.
"S-she d-died..." Zygarde said through tears.
Gardevoir didn't know how to react. He knelt beside her and started
to cry.
