Silvally was a Pokémon created by Faba to fight Ultra Beasts. Four years prior to the start of Sun & Moon series, Lillie was attacked by a mysterious Ultra Beast, and was saved by Silvally. The fierce expression Silvally had on its face, combined with the emotional trauma of the incident, left Lillie with a fear of touching Pokémon. Following this incident, Silvally was given a restricting helmet by Faba, turning it intoType: Null. Some time later, it was stolen by Gladion, who felt sorry for the Pokémon and wanted to rescue it from Faba's cruel experiments.
Silvally first appeared as a Type: Null in Rising from the Ruins!, in a secluded cave on Akala Island. After being called out, Silvally began to act restless due to the stress brought by its helmet. The Pokémon eventually calmed down after being comforted by Gladion. It later appeared in A Dream Encounter!, where it began acting restless again. Gladion inferred from its uneasiness that it had sensed the presence of an Ultra Beast.
In A Masked Warning!, Silvally was seen training with Gladion on Ten Carat Hill until they were interrupted by Ash, who had been teleported there by Nebby. Silvally started growling at Nebby, causing Nebby to start crying and leading Gladion to the conclusion that Nebby is the Ultra Beast his Pokémon sensed before. Later, Gladion accepted Ash's challenge to battle, choosing Silvally to fight Ash's Lycanroc. Silvally was able to overpower Lycanroc and managed to throw it in the nearby lake. This dirtied Lycanroc's fur, which temporarily caused it to go berserk. Once Lycanroc had calmed down, the battle continued, and Silvally quickly defeated Lycanroc.
Silvally briefly appeared in Night of a Thousand Poses!, where it was seen with Gladion after Lillie had been teleported to him by Nebby. Upon seeing Silvally, Lillie recalled a brief scene of the Pokémon from her traumatic incident, which made her believe Silvally attacked her and once again rendered her unable to touch Pokémon. In Mission: Total Recall!, Faba stole Silvally back after defeating Gladion's Umbreon and Lycanroc and putting its Trainer to sleep with Hypnosis. Gladion, together with Lusamine, later retrieved Silvally from Faba's office and used it to confront Faba, who was trying to erase Lillie's memories and cover up his mistakes. Ordered to save Lillie, Silvally broke its mask and attacked Faba's Alakazam, breaking the Psychic hold it had on Gladion's sister. It then used the RKS System and a Dark Memory to turn into a Dark-type and defeated Faba's Pokémon with a Dark-type Multi-Attack. After being brought to safety, Lillie fully remembered Silvally's heroism four years ago and thanked it for rescuing her, which allowed her to completely overcome her fear.
In Family Determination!, Gladion used Silvally to help him and his sister overcome obstacles on the way to the Altar of the Sunne. Standing right before the altar was a horde of Jangmo-o and Hakamo-o, led by a TotemKommo-o. Thanks to the help of Lillie and Snowy, Gladion was given enough time to give Silvally a Fairy Memory, allowing it to resist Kommo-o's Clanging Scales and defeat it. Silvally was later used to battle Lusamine's Absol alongside Gladion's other Pokémon. Having its feet frozen in place by Absol's Ice Beam, Gladion used a Fire Memory, allowing Silvally to melt the ice and counterattack. This released the hold it had on Gladion's other Pokémon thanks to its Mean Look. Gladion later used a Steel Memory to change Silvally to a Steel-type, allowing it to ferry him across the sea of poison the Nihilego-possessed Lusamine left behind.
In Filling the Light with Darkness!, Gladion had to calm Silvally down again. Gladion recognized its behavior as a bad omen. It was later sent out as its Trainer and the other Ultra Guardians witnessed an Ultra Wormhole form above the Altar of the Sunne, where it sensed twopresences coming out. In the next episode, Silvally teamed up with Pikachu to free Nebby and Lunala from Team Rocket's electric net. In The Prism Between Light and Darkness!, it was revealed that Silvally was able to perform Breakneck Blitz, which it used along with Ash's Pikachu, Kiawe's Marowak, and Lana's Popplio's Z-Moves to help separate Nebby from Necrozma and to give Necrozma enough Z-Power to turn it back into its true form. However, this attempt failed as the amount of Z-Power was too little and Necrozma used it to power itself up instead. Silvally later joined the rest of Alola in showering Necrozma with Z-Power, causing it to separate from Nebby and revert to its normal form. Necrozma still had not absorbed enough Z-Power though and tried to capture Nebby again, but was stopped in its tracks by Silvally who attacked it with Air Slash.
In SM129, Gladion used Silvally during the Battle Royal round of the Manalo Conference, where it was able to defeat several Pokémon. It was among the 16 Pokémon remaining at the end, securing Gladion a place in the next round.
Personality and characteristics
Silvally has the ability to sense the presence of Ultra Beasts and Ultra Wormholes. Silvally often becomes stressed when it senses danger, barking and lashing out when it feels threatened. As a Type: Null, its helmet was also a source of anxiety for it. Despite its anxiousness, it appears to trust its Trainer, and can be calmed down with Gladion's words. It eventually became able to trust Gladion enough to use the full extent of its power, breaking its restraints. It also has a strong connection to Lillie, having saved her from Nihilego during her childhood. It inadvertently caused Lillie's fear of Pokémon, and was ultimately what caused her to stop fearing them. Initally, Gladion wanted to keep Silvally's existence a secret, likely to prevent Faba from discovering that it was he who stole his research.
After breaking its mask, it gained access to the RKS System.
Gladion's Type: Null was one of the three Type: Null created by Faba of the Aether Foundation to be an "Anti-UB Fighting life-form". Codenamed "Beast Killer", the Type: Null were given cells taken from all known Pokémon types with the intention of giving it the ability to shift between types by holding a corresponding memory, an ability originally inspired by the myths researched at Canalave Library. This ability led the Aether Foundation to give it the name Type: Full (Japanese: タイプ：フルType: Full). However, all three rejected the RKS System and went berserk. After being subdued, the three Type: Full were given limiter helmets to lessen the effects of the RKS System's rejection and were put into permanent cryogenic stasis, and the "Beast Killer" project was deemed a failure, and their name changed to Type: Null.
At some point before the events of the game, Gladion was able to free one of the Type: Null, which he adopted as his own in the hopes of finding a way to undo the effects of the limiter helmet and allow it to use the RKS System. Gladion, who sympathizes with Type: Null due to their shared connection with the Aether Foundation, often calls it Null. Gladion and Type: Null battle against and alongside the player at various points of the story, and eventually, the two become close enough that Type: Null no longer needs its helmet, and evolves into Silvally, a new form named by Gladion himself according to the Rotom Pokédex. Gladion and Silvally later challenge the player at the foot of Mount Lanakila, where it holds the memory matching the starter of the type the player's starter is weak to.
In the finals, Type: Null was used to battle against Sun. First, it went up against Sun's AlolanMeowth, Cent, which it easily defeated while Sun was distracted. Sun then switched out for his Litten, Dollar, but his fireballs were blocked by Type: Null's mask, preventing him from doing any damage. Sun attempted to get over this by having Dollar lodge hairballs inside of Type: Null's mask and then lighting them on fire to damage Type: Null internally, but Gladion saw through the strategy and had Type: Null shake the hairballs out.
As a Type: Null
Angered by Sun's apparent lack of seriousness during their battle, Gladion chastises Sun and questions why he's even participating. Gladion's words anger Sun, which causes the cast on his injured arm to burst open, revealing the Sparkling Stone underneath. A powerful energy shoots out from a crack in the sky and lands on the Sparkling Stone before moving towards Dollar. The energy powers up Dollar's Ember, allowing it to create a powerful sea of flames that defeats Type: Null. Despite having one Pokémon left to use, Gladion was forced to give up the tournament by Hala, making Sun the victor.
In The Wild Full-Power Pose of Fire, at the Ruins of Life, Type: Null was used to attack Sun, Moon, and Kiawe as they were preparing to stop Gladion from kidnapping Tapu Lele. Hoping to have Sun defeat Gladion with the Z-Move he recently mastered, Kiawe threw his Z-Ring to Sun for him to use, only for Type: Null to destroy it. While Gladion claimed he wouldn't have lost regardless, a voice calls out and argues that Gladion wouldn't have destroyed the Z-Ring if he truly believed that. The voice is revealed to be Kahili, who uses her golfing skills to send her Toucannon out to distract Type: Null long enough to deliver Sun his own Z-Ring.
Now with a Z-Ring of his own, Sun successfully has Dollar perform Inferno Overdrive on Type: Null. Though the attack succeeds, Type: Null doesn't faint and its mask begins to crack. Worried as to what might happen if the mask completely broke, Gladion switched Type: Null out for his Porygon.
In PASM14, Gladion arrived at Po Town for the first. Immediately after his arrival, Gladion was attacked by a Salazzle, forcing him to have Type: Null blow it away with Air Slash. The Salazzle's Trainer then revealed herself to be the Team Skull Admin Plumeria, who was testing Gladion to see if he was good enough to be an Enforcer.
In PASM22, Type: Null was used to battle Celesteela and Guzzlord at Route 10 in order to prevent them from reaching Hokulani Observatory. While Type: Null easily took down Celesteela, Gladion was distracted when Lillie appeared and called out to him. Guzzlord proceeded to attack Lillie, only for Type: Null to swoop in and take it down, evolving into a Silvally in the process.
In PASM23, Gladion and Lillie rode on Silvally's back as they traveled through Poni Plains on their way to the Altar. As they passed through the area, a Xurkitree appeared and attacked, forcing Silvally to stop and battle it.
Personality and characteristics
Silvally is a powerful and determined Pokémon who is capable of handling itself. As a Type: Null, it was very sluggish due to its helmet, but made up for it with its incredible strength. Its helmet also bolstered its defense, allowing it to take multiple hits without taking any damage. It has the ability to sense Ultra Wormholes and can fight any Ultra Beast with ease due to it being created with that goal in mind.
