Dia (Japanese: ディア Dia) is a recurring character who appeared in Pokémon the Series: Sun & Moon. He is a resident of the Ultra Ruin, a world that was devastated by the appearance of the Ultra Beast Guzzlord, and a former member of the Ultra Rangers.


Dia debuted in Battling the Beast Within!, where he encountered Ash and Pikachu when they found themselves transported to his home world from an alternate Melemele Island by a Shiny Tapu Koko and the Tapu Koko of Ash's world. Ash and Pikachu were attacked by a Guzzlord, but Dia saved them using his friend Zeraora. After introducing himself, he explained to Ash what had happened to his world and then had a battle against Ash, which Dia was able to win. Dia eventually took Ash to some ruins, which Ash recognized as the Pokémon School.

Dia reappeared in Parallel Friendships!, where he explained to Ash and Pikachu how his universe is different compared to his. He later explained that the reason Ash was unable to use a Z-Ring is because his Tapu Koko left the Alola region and all life was destroyed by Guzzlord. Since that time, Dia became disillusioned with Tapu Koko and believed that his efforts of stopping the Ultra Beast were hopeless. However, all of that changed when he witnessed Ash and Pikachu's training, which turned into a competitive battle against Zeraora. While Pikachu won the match, it reinvigorated Dia and Zeraora's ambitions.

The battle also attracted Guzzlord's attention, so Dia, Ash, Pikachu, and Zeraora were forced to put a new plan into action, luring Guzzlord to the Ultra Wormhole below the debris. When they attempted to ensnare the Ultra Beast in Pikachu's Electroweb, Guzzlord fought back. Dia wanted to retreat, but Ash refused to give up. Just when they were about to be consumed by Guzzlord, Tapu Koko appeared and trapped it with its electricity. Tapu Koko reactivated Ash and Dia's Z-Rings, and together, they used their Z-Moves to push Guzzlord through the Ultra Wormhole. Dia thanked Ash for his help, and realized that it was time for Ash to return to his home world. He and Zeraora battled Ash again, which caused a dimensional rift to open up and allow Ash and Pikachu to return to their home world. The pair said goodbye to Dia and Zeraora and promised to battle them again one day before going their separate ways.

He reappeared during a flashback in Z-Move Showdown!.


Dia is a gruff and stoic individual, which was brought by his experiences with Guzzlord. However, he also has a hidden kindhearted and generous nature, as he was eager to share his story with Ash, in addition to offering him food and shelter. Dia is also very competitive in battle. He used Zeraora's strong will and power to overwhelm his opponents.

He is also incredibly optimistic and maintained a clear focus on his goal; to send Guzzlord back to its home world. Dia was well aware of the dangers of the situation, hence his initial hesitance and opposition to Ash's assistance. After seeing Ash's performance in battle and strong friendship with Pikachu, he allowed Ash to join his mission. Ash served as a catalyst and helped reinvigorate Dia and Zeraora's focus and ambitions.



Zeraora is a Pokémon that Dia befriended after it saved him from being attacked by a Guzzlord and realizing that they wanted the same thing, to send Guzzlord back to its home world. It was first used to save Ash and Pikachu from Guzzlord. It then battled Pikachu and won.

Zeraora has been shown to be a solitary Pokémon. Its close companionship with Dia and the fact that it offered a Sitrus Berry to Pikachu is evidence of its kind nature.

It reappeared during a flashback in Z-Move Showdown!.

Zeraora's known moves are Close Combat, Plasma Fists, Quick Attack, and Slash.
Zeraora can perform the Z-Move Gigavolt Havoc.
