RKS System (Japanese: ＡＲシステム AR System) is an Ability introduced in Generation VII. It is the signature Ability of Silvally.

Effect

In battle

RKS System changes the type of the Pokémon with this Ability depending on the memory attached, as well as Multi-Attack.

Role Play, Gastro Acid, Worry Seed, Simple Beam, and Entrainment fail if the target has the Ability RKS System. Skill Swap fails if either Pokémon has RKS System. RKS System cannot be copied by Trace, Power of Alchemy, or Receiver. RKS System cannot be replaced by Mummy or suppressed by Core Enforcer. If a Pokémon other than Silvally obtains RKS System with Imposter or Transform, the Pokémon will copy the form of the target Silvally regardless of its own held item.

In Generation VIII, RKS System is hampered in performance when Dynamaxing. While RKS System will still change the current type of Silvally depending on the Memory, it cannot influence the typing of Multi-Attack while Silvally is Dynamaxed.

Outside of battle

RKS System has no effect outside of battle.

Trivia

• The name of this Ability is a reference to Arceus, with its English name being similar to the pronunciation of "Arceus". In German, Spanish, French, and Italian, its name is instead a reference to Arceus's category, the Alpha Pokémon.
  • The company RKS Laboratories (Japanese: アルセウス製薬 Arceus Pharma) in Galar has a logo similar to the rings on Arceus's body, furthering the connection.
