Ultra Beast/TCG

Ultra Beasts were introduced to the Pokémon Trading Card Game in the TCG Crimson Invasion expansion as a classification of TCG Pokémon cards. Certain TCG attacks, TCG Ability (Abilities), TCG Trainer cards, and TCG Special Energy cards interact specifically with Ultra Beast cards. Unlike the core series of games, the TCG considers Dusk Mane Necrozma, Dawn Wings Necrozma, and Ultra Necrozma to be Ultra Beasts. Every Ultra Beast card has an attack or Ability that affects or is affected by the player or opponent's TCG Prize cards. In the case of an Ultra Beast GX card, this is always its GX attack. Several of the Ultra Beast-related Trainer cards interact with Prize cards as well. This association with Prize cards may be a reference to the Ultra Beasts' Ability in the core series, as both Beast Boost and Prize cards center around knocking out the opponent's Pokémon.

Ultra Beast cards are distinguished by a red Ultra Beast label superimposed on the card art below the and TCG type. Ultra Beast GX cards have a red graphic instead of the blue  graphic depicted on other other Pokémon-GX cards. Additionally, the GX attack bar, effect text, Pokémon-GX rule box, and outlines for the TCG Full Art card (Full Art) graphics are colored red rather than blue. This red motif may be a reference to the red aura surrounding wild Ultra Beasts in the core series of games.
