EX Hidden Legends is the name given to the fifth main expansion of the EX Series of the Pokémon Trading Card Game. In Japan, it was released as Undone Seal, the fourth and final expansion in the Pokémon Card Game ADV Era. It is based on Pokémon Ruby and Sapphire, featuring Generation III Pokémon and the legendary giants, Regirock, Regice, and Registeel. The English expansion was released on June 14, 2004, while the Japanese expansion was released on January 16, 2004.

Due to the removal of the Dot-Code strip, the bottom border of the card returned to normal. The Reverse Holofoil cards featured a new design. Several Holofoil Energy symbols appeared on the artwork. The type of the Pokémon was displayed as a faint foil symbol in the attack box. Reverse Holofoil versions of the Rare Holo cards have a foil rarity symbol.
