Gladion's Silvally/Games

Silvally appears in as Gladion's main Pokémon and partner.

As Type: Null, Silvally 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 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 undefined 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 of the type the player's starter is weak to.

In Pokémon Sun and Moon, after the player becomes, and Gladion becomes acting president of the Aether Foundation, he discovers another of the Type: Null that was put into stasis. He entrusts it with the player at Aether Paradise's Conservation Area, knowing they will take good care of it. In Pokémon Ultra Sun and Ultra Moon, Gladion and Silvally leave for Kanto and Johto to train after the player becomes Champion, and leave the other Type: Null with Wicke to give to the player at Ancient Poni Path on their way to Poni Grove.
