Collect 151 is a special expansion featuring all 151 Pokémon from Generation I. It was revealed on December 22, 2024, as part of the introduction of the Scarlet & Violet era in the Simplified Chinese language.

Although the set is the equivalent of the Japanese Pokémon Card 151 and international 151 expansions, a number of changes have been made to its card list:

• all Trainer cards have been removed, leaving only Pokémon cards;

• all 18 illustration rare cards (with an AR rarity) from the original expansion have been removed;

• 18 shiny rare cards (with an S rarity), all of which are reprints from this set originating from Shiny Treasure ex, have been added;

• the special illustration rare prints of Venusaur ex, Charizard ex, and Blastoise ex have been removed;

• the shiny ultra rare prints of Wigglytuff ex, Alakazam ex, and Mew ex from Shiny Treasure ex have been added;

• the special illustration rare print of Mew ex from Shiny Treasure ex has been added;

• four illustration rare prints of Pikachu, each illustrated by Oswaldo KATO, have been added and are currently exclusive to the Simplified Chinese language.

Collect 151 Gathering is the last of the 4 sets completing the original color-in banner artwork and adding the last exclusive Pikachu AR card 173/151
