Gladion is a pale young boy with yellow hair and green eyes. His hair appears to be cut into squares and is styled for his bangs to perpetually obscure one of his eyes. He wears a grey hooded shirt with a red decoration on it, some black slashed sleeves, slashed black pants and red shoes with grey soles and black laces. He also has a red rectangular bag around his waist. In addition, he also wears a red-brown Z-Ring on his left wrist.
Gladion is a serious and calm trainer, who is looking for worthy opponents in Pokémon battles. To the rest, he is a "lone wolf" who avoids meeting with his sister. Despite this, he is noted by others how to still have kind behavior, shown when he told his sister to take care of her Pokémon.
While Gladion does not visit his sister often, he swore to protect her, after her encounter with the Ultra Beast. Due to that incident, he is distrustful of Ultra Beasts, and swore to hunt them down.
Gladion, as a young boy, watched as his sister, Lillie, was attacked by an Ultra Beast. Lillie was terrified, while Gladion was not brave enough to defend her. Suddenly, a Silvally arrived, which defeated the Ultra Beast. While Lillie lost memory of the encounter and became scared of Pokémon, Gladion took the Silvally as his own Pokémon, and swore to protect his sister.
Gladion was also motivated to go on a journey to find more about himself, as well as to train alone. Thus, he left Lillie and the mansion.
Pokémon the Series: Sun & Moon
Gladion was walking with Umbreon through the streets when he was ambushed by three Team Skull grunts. Gladion ignored them and continued walking, but the grunts demanded him to hand over his Umbreon. Gladion eyed them, as the grunts sent their Pokémon to attack. Instead, Gladion sent Lycanroc, who used Stone Edge to defeat all three of Team Skull's Pokémon. Gladion continued on and was seen by Team Rocket. He later challenged a sailor, and had his Lycanroc defeat the sailor's Blastoise, impressing the crowd. Ash observed the battle and was told by Rotom that Gladion was the famous trainer of the island. Ash went to Gladion and introduced himself, wanting to challenge him. Gladion ignored him but was called by Lillie, who addressed Gladion as her brother. Gladion was surprised, and when Lillie showed she could touch her Pokémon, Snowy, Gladion simply told how that was great and she should keep it up and refused to visit the mansion. He also saw Ash had a Z-Ring and was told by Ash that he got it from Tapu Koko. Seeing how Ash was important, Gladion decided to at least think of the challenge, then left. During the morning, Gladion sent Umbreon to deliver a letter to Ash to accept the challenge. Ash soon came, as Gladion told he wanted to battle him because of his ties with Tapu Koko. As the two had their Rockruff and Lycanroc battle, Team Rocket came and snatched Lycanroc and Pikachu. Ash's Rockruff managed to Bite the net and free Pikachu and Lycanroc. Gladion decided to finish this, as he used the Z-Ring to have his Lycanroc use Continental Crush, blasting Team Rocket away. Since Ash wanted to use the Rock-type Z-Move, Gladion advised him to challenge the Kahuna of Akala Island. Just as they were about to continue the battle, Lillie came and cheered for her brother. Since Ash had to go to school, Gladion told they should postpone the battle. He shook hands with Ash and left.
As Ash faced Olivia, who had her Lycanroc use Continental Crush, Ash remembered Gladion and his Lycanroc, the former having the latter use the same Z-Move. Gladion's Lycanroc heard Rockruff's howling on Akala Island. Gladion had Lycanroc to go investigate and be back by nighttime. Gladion went to a cave and sent his Type: Null out inside it. However, due to the strain of its helmet, it acted restlessly. Gladion ran over to Type: Null to comfort it and told it that everything would be fine. He exclaimed it would be a problem if someone saw it outside. Sometime later, Type: Null acted restless again as it sensed the birth of a young Cosmog named Nebby. Gladion reminded Silvally it would be a problem if someone saw it outside the cave. Gladion managed to calm it down, but it sensed the coming of the Ultra Beast.
Later, Gladion, Silvally, Lycanroc, and Umbreon were about to battle against a group of Pinsir, but Nebby teleported Ash, Pikachu, and Ash's Lycanroc to his location. They fell on top of the Pinsir and they attack them out of anger. Gladion's Silvally was able to chase them away, then started to walk too close to Nebby, which frightened the latter to the point of tears. Gladion calmed Silvally down, and asked Ash why did he have the Ultra Beast, Nebby. Ash denied Nebby was a dangerous one. Gladion became flustered, until Ash tells him that Solgaleo and Lunala trusted him to take care of Nebby. He admitted that Nebby Teleported him, Pikachu, and Lycanroc to his location because Ash wanted to show Gladion his Dusk Form Lycanroc, who is neither Midday or Midnight Form. Gladion told that they were at Ten Carat Hill. Ash told Gladion about Lillie's progress, that she managed to touch Pikachu, taking care of Snowy, and nicknaming Nebby. Gladion was shocked, and told Ash that Lillie was attacked by an Ultra Beast a few years ago, and was saved by Silvally. Due to that incident, Gladion believed Ultra Beasts were not worthy to live in this world, and swore to hunt Nebby down if it showed traits of the Ultra Beasts. He also wondered kind of trainer Ash was, since Tapu Koko personally gave him a Z-Ring, owns a strange Lycanroc, and Solgaleo and Lunala entrusted him with Nebby. Ash did not answer his questions, but believed he could learn more through a battle. Gladion used his Silvally for the first time in an official battle, while Ash used his Lycanroc. Silvally proved to be a powerful opponent, landing some powerful attacks, and dodging most of Lycanroc's despite its heavy mask. Silvally's Crush Claw eventually knocked Lycanroc into a nearby puddle, messing up its fur. With its fur ruined, Lycanroc flied into a fit of rage and attacks Silvally without Ash's commands, forcing Ash to restrain Lycanroc. Lycanroc's rage frightens Nebby, causing it to release a powerful screech which cleans Lycanroc's fur, calming it down. Ash and Gladion decide to continue the battle, and Silvally eventually defeats Lycanroc with Crush Claw. After the battle, Ash decided to head back to Professor Kukui's house, while Gladion knew this experience has strengthened Silvally and Lycanroc, too. Gladion ordered Ash not to say a word about Silvally to anyone, especially Lillie, before walking away.
A few days later, Nebby teleported Lillie to Gladion's location after she strongly desired to see him again. Gladion was startled, asking Lillie why she's there. Lillie was about to express her desire to spent time with him like before, but Silvally leapt right right in front of her. The sight of Silvally caused Lillie to partly remember the incident that caused her fear a few years ago. Gladion rushed over to a terrified Lillie, but Nebby teleported Lillie back to her classmates before he could reach her.
Later, Gladion came to Ash, furious for letting Nebby take Lillie to him. Gladion thought that it would've been better for Lillie if she never remembered the incident. He later returned to his hotel room, where Faba was waiting for him, and ordered "the young master" to return his Silvally. Gladion refused, remembering that Faba mistreated Silvally. and used Lycanroc and Umbreon to protect it. Faba used his Alakazam and Hypno to battle Gladion's Pokémon. Faba's Alakazam and Hypno's quickly overpowered Lycanroc and Umbreon with Hypnosis and Psychic. Gladion attempted to use his Silvally as a last resort, but Faba's Hypno used Hypnosis to render him unconscious. Gladion struggled to resist the powerful Hypnosis, but his vision became blurry and eventually fell unconscious, as Faba stole Silvally. The next day, Gladion went to Aether Paradise where he saw his mother, Lusamine, in her office. Gladion angrily demanded to know where Silvally was, but Lusamine was completely unaware of the situation. Though she remembered that it was a Pokémon that Faba created to fight Ultra Beasts, Faba had told her that the project failed. Gladion assumed that Faba had been lying, because Silvally had saved Lillie from an Ultra Beast a few years ago. While the two were searching for Silvally in Faba's office, Gladion informed Lusamine of the incident that happened a few years ago. Gladion furiously pointed out the Lusamine should've known this despite Faba's lies, and chastised her for her obsession with Ultra Beasts caused Lillie to become unable to touch Pokémon. Lusamine apologized to him, but Gladion stated that he was not the one that she should apologize to. Gladion finds Silvally's Premiere Ball, but heard an alarm coming from the basement. Gladion and Lusamine rushed down there, where they found Lillie being held in the air by Faba's Alakazam's Psychic, and Ash, Pikachu, Snowy, and Nebby being held down by Faba's Hypno's Psychic. Gladion sent out Silvally to save Lillie, who broke free from its mask to save Lillie from Alakazam's Psychic. The evolved Silvally saved Lillie, causing her to fully remember the incident that happened a few years ago. Gladion equipped Silvally with a Dark-Memory Disc, changing it into a Dark-Type Pokémon, and defeated Faba's Alakazam and Hypno with Multi-Attack, freeing Ash, Pikachu, Snowy, and Nebby from Hypno's Psychic. Having learned that the whole ordeal was a misunderstanding, Lillie apologized to Silvally and thanked it for saving her twice, and gave Silvally a hug, much to everyone's surprise.
Sometime after Faba had escaped, Gladion was searching for him nonstop. He eventually visited his mother in her office, who asked if they found Faba. Lusamine denied, and as Gladion was about to continue his search, Lusamine stops him from leaving. She wanted to thank Gladion and to report they were still searching for Faba, but Gladion ignored her and left. After Faba kidnapped Nebby and disappeared, Gladion arrived to the Pokémon School. Told about Faba's newest incident, Gladion believed he was at Aether Foundation. To catch up to them, Lillie called upon a jet from her mansion. Gladion told Lillie to stay behind, but Lillie wanted to save Nebby too and insisted that she came along. Gladion was surprised by his little sisters determination, and let her come along with Ash, too. Along the way, they informed Lusamine of the situation. Along the to the basement, Gladion assumed that Faba plan was to use Nebby to summon another Ultra Beast. When they arrived in the basement, they saw Faba using a machine, trapping Nebby and using its power to create an Ultra Wormhole. While Ash tackled Faba, Umbreon destroyed the machines that was trapping Nebby with Shadow Ball. After Nebby was freed, it transformed, much to everyone's surprise. However, the machine absorbed enough energy to create an Ultra Wormhole and an Ultra Beast appeared - the same Ultra Beast that attacked Lillie a few years ago, which Faba named as UB01: Symbiont. UB01 then attacked everyone, so Gladion sends out Silvally to protect Lillie. UB01 proved to be too strong despite everyone's attempt to get it out of their world, and descended down to try to attack Lillie. Gladion was determined to protect his little sister, by letting UB01 take him away, but Lusamine pushed him out of the way and gets carried away through the Ultra Wormhole, leaving Lillie and Gladion horrified.
After Lusamine's abduction, Gladion approached Lillie, who was overwhelmed by the shock. While Wicke and Burnet were arguing with Faba, Ash wanted to help Gladion, who replied from then on, the issue became a family matter and did not accept his help. Regardless, Burnet advised them to return to Melemele Island, and the group went back home. At night, Gladion walked into Lillie's room, who lied to him about going to bed. Gladion knew Lillie was plotting something, looking at her new clothes and new hairstyle. Though Lillie still lied to him by saying it's her sleepwear, Gladion asked her how will she open a Ultra Wormhole. Lillie admits that she did not know, but Gladion admitted he knew of a way. The two went on Silvally, out of the mansion. The next day, they arrive to Poni Island. they find an old door with statues of Rowlet, Litten, and Popplio in front of it. Lillie believed it was a puzzle that they had to solve by pushing the statues in place, but Gladion simply pushed the door open. He assumed it was a trap, and had Silvally push the Popplio statue in place, which revealed a spike trap. Gladion ordered Lillie to be careful and not touch anything. They came to a steep cliff, where Lillie thought there was an invisible bridge connected to the other side, and drops some sand in order to find it. Gladion doubted her, telling her to get on Silvally, as they leapt away. He informed her Lillie that there was a bridge, but was destroyed a long time ago. Lillie started thing she was slowing her brother down, but decided to continue. Gladion knew that Lillie won't stay put even if he told her, and the two proceed forward. They came to an old ruin, where a group of Jangmo-o, Hakamo-o, and their leader Totem Kommo-o ambushed them. Lillie sent out Snowy to battle the Jangmo-o, and Hakamo-o while Gladion and Silvally deal with Totem Kommo-o. Totem Kommo-o's hard scales were too hard for Silvally's Crush Claw, and Totem Kommo-o did not take much damage. Lillie advised Gladion that if Silvally could change into a Fairy-Type, they might be able to beat Totem Kommo-o. Gladion was to equip Silvally with a Fairy-Type Memory Disc, but a Jangmo-o disarmed him and the Memory Disc landed underneath Totem Kommo-o. Lillie and Snowy created a path by attacking the Jangmo-o and Hakamo-o and freezing the ground with Powder Snow. Gladion and Silvally skated across the frozen floor while Totem Kommo-o charged up a Clanging Scales attack. Gladion retrieved the Memory Disc and equipped Silvally, protecting the two from Kommo-o's attack. Silvally defeated Totem Kommo-o with a Multi-Attack; Lillie congratulated her brother, but Gladion gave the credit to Lillie. The ceiling began to crumble down on them, so the siblings rode on Silvally to reach the exit, and were saved from a falling rubble by an Electro Ball. After they barely make it out to the Altar of the Sunne, Ash and his classmates, along with Professor Kukui, came out, too. Gladion reminded Ash that was a family situation, but Ash reminded that people in Alola shared everything, including family situations. Persuaded by Lillie that they could use all the help they need, Gladion permitted them to stay. Suddenly, everyone saw as the Guardian Deities of Alola showed up for an important meeting.
The group encountered the Guardian Deities, and asked them to lend the power to open an Ultra Wormhole, since Gladion reminded they were to meet Solgaleo at the place. Gladion watched as the Guardian Deities showed a screen presenting Nebby's creation, and how Ash found it. Gladion became impatient, since they had to save his mother, but Lillie thought they should wait what the Guardian Deities had to show. The Guardian Deities performed a ritual, which caused Nebby to evolve into Solgaleo, which astounded the group. In addition, the Guardian Deities upgraded Ash's Z-Ring, giving it a different slot, and black color. Gladion went on Solgaleo, who opened an Ultra Wormhole to cross into the another dimension.
The group arrived into the Ultra Space, where they soon found a bunch of Ultra Beasts, UB01: Symbiont, floating around. The group was to search for Lusamine, who touched Sophocles. They saw Lusamine darker, fused with the Ultra Beast, floating around, and screamed they stayed away from her. Lillie ran to her mother, forcing Ash and Gladion to go after her. Lusamine blocked the way with boulders, so Ash protected Lillie while Gladion's Umbreon destroyed the boulders with Dark Pulse. Gladion believed UB01: Symbiont was the cause of Lusamine's strange behavior, and feared it was draining her energy. Lusamine floated away, leaving behind a trail of boulders wherever she went. The children used that trail to follow her. Gladion thought that part of her real personality was being shown, because of her life-long dream to meet an Ultra Beast, which made Gladion believe Lusamine wasn't aware she's being controlled. Lusamine started sending Pokémon, so Gladion split with the group to let Ash, Pikachu and Solgaleo advance on to confront Lusamine. Gladion, his Lycanroc, Umbreon, and Silvally faced Absol, who used Ice Shard on Silvally's feet, as well as Mean Look on Lycanroc and Umbreon, immobilizing them.
With all three of his Pokémon immobilized, Absol continued to attack them. Gladion equipped Silvally with a Fire Memory Disc, changing it into a Fire-Type Pokémon. Silvally broke free from the ice, and with Absol distracted, Gladion had Lycanroc use Continental Crush to defeat it. However, Absol was restored to its health, due to the Ultra Beast energy powering it up. Gladion realized until UB01 was defeated, this fight would continue on; he left Lycanroc and Umbreon deal with Absol, and rode off on Silvally. Gladion met up with Lillie, Snowy, Ash's Lycanroc, and Lusamine's Clefable, whom Lillie managed to free from the Ultra Beast's control, while Ash, Solgaleo and Pikachu were facing Lusamine across the toxic goo. Gladion informed Ash of the situation, and was worried about the others. Lillie went atop Clefable, who was protected from the toxic goo with Magic Guard ability, while Gladion equipped Silvally with a Steel-type Memory Disc to make it immune to that. Lusamine rose up, creating a mountain of rocks. Lillie went to talk things over with her mother, and managed to snap out of her state. However, the Ultra Beast refused to let Lusamine go and made her attack Lillie, who was saved by Gladion and Silvally. Thr Ultra Beast grew bigger and covered itself with more rocks and spikes, making Gladion believe UB01 was as interested in learning about humans as was Lusamine about Ultra Beasts. Ash wanted to use a Z-Move with Gladion, who already had Lycanroc use Continental Crush against Absol. Instead, Gladion and Lillie distracted Lusamine to let Ash have Pikachu use a new Z-Move, which was 100 times stronger than Thunderbolt. The powerful Z-Move defeated the Ultra Beast, allowing Lillie and Gladion to pull their mother out of it, who was unconscious and covered in black ink. While the Ultra Beast fled, Lusamine woke up, causing all of her Pokémon to stop the battles with the rest of Ash's classmates. Gladion and Lillie help their mother stand up, and Lusamine apologized to them. Gladion watched as his sister cried in her mothers arms, relieved mother has snapped out of her state. The group came out of the Ultra Wormhole by riding on Solgaleo, pleasing Kukui and Burnet for their arrival. However, Gladion was not glad to see that Sophochles has brought a rock from the Ultra Space. In the end, Lillie, Gladion and Lusamine took a helicopter to Aether Paradise.
The night before Professor Kukui and Burnet were getting married, Ash and Pikachu were greeted by Gladion and his Umbreon. Ash invited Gladion to the wedding ceremony, Gladion replied Ash he was going on a journey, due to his amazement of the Z-Move Ash and Pikachu did in the Ultra Space. Thus, Gladion swore to do the Island Challenge, and asked of Ash to congratulate Professor Kukui and Professor Burnet for him. As Gladion left, Ash promised to him that he'll continue his Island Challenge too, and offered to challenge him to another battle someday, causing Gladion to smiled and waved goodbye.
Later, Ash remembered Gladion and his Type: Null during his battle against Nanu and his Krookodile when Lycanroc's fur got dirty after being hit with Sand Tomb and Mud-Slap.
