The Munikis Zero expansion, also known internationally as Nihil Zero or Perfect Order, is a pivotal Japanese Pokémon TCG set. As the third main expansion of the Mega Evolution M3 series, it draws heavy inspiration from the Pokémon Legends: Z-A video game, specifically focusing on the restoration and balance of Lumiose City. The set’s name is derived from the Japanese term munikisuru meaning "to return to nothing," which thematically ties into its central mascot, Mega Zygarde ex, a legendary powerhouse that represents order and the reset of the natural ecosystem.

Comprising over 80 cards in its main set and 117 cards total including secret rares, the expansion reintroduces the Mega Evolution mechanic as a dominant force in the meta. Collectors and players alike are drawn to high-end "Mega Ultra Rare" cards, which feature a distinctive gold finish and low pull rates, as well as Special Illustration Rares for fan favorites like Mega Zygarde and Meowth ex. The set also marks the debut of new human characters and supporters like Tarragon, Naveen, and a nostalgic "Rosa's Encouragement" card, further cementing its status as a landmark release for the TCG season. Each pack contains 5 cards.
