'''Shadow Pokémon''' (Japanese: '''シャドウポケモン''' ''Shadow Pokémon'') are Pokémon in {{g|GO}} that have been modified by [[Team GO Rocket]] through unnatural means, resulting in them having dark, flaming auras (except Mewtwo, and Apex Shadow Pokémon) and angry, red eyes. By defeating members of Team GO Rocket, players can capture Shadow Pokémon and restore them to a more normal state through purification.

In the {{GO|Pokémon Box}}, Shadow Pokémon have a [[File:GO Shadow icon.png|24px]] icon at the bottom left of their image, and Purified Pokémon have a [[File:GO Purified icon.png|24px]] icon. Similar to {{DL|Trade (GO)|Lucky Pokémon}}, the [[Pokédex]] will keep count of the number of Pokémon that the player has purified of that species; evolving a Purified Pokémon will not increment the evolution's purified counter.

The {{GO|Move|Charged Attacks}} {{m|Frustration}} and {{m|Return}} are exclusive to Shadow Pokémon and Purified Pokémon, respectively. Unlike all other moves, these are not re-rolled upon [[evolution]]. On [[Community Day]]s, eligible Purified Pokémon may learn event-exclusive moves, replacing Return upon evolution, even if that Pokémon already knows a second Charged Attack. Shadow Pokémon can only learn their event-exclusive moves if Frustration is first forgotten, either by purification or using a [[Charged TM]] during certain events. Once forgotten, Frustration and Return cannot be relearned, even if an [[Elite Charged TM]] is used, or if it evolves.
