The sixth Arceus Arc Celebration was a special battle event in Pokémon Masters EX celebrating the addition of the sixth chapter of the Arceus arc to the main story. It was focused on the sync pair Volo (Alt.) & Giratina.

The "Volo EX Master Fair" gave players an increased chance of recruiting Volo (Alt.) & Giratina from the beginning of the event to October 25, 2025.

During this event, players could earn event points by completing battles. Players received rewards based on the number of points accumulated, including 5★ Scout Tickets, a Support Move Candy Coin, a 5★ Power-Up, and medals. All battles could be challenged an unlimited number of times except Daily Extreme Battle 1, which could only be challenged once per day.

The player could battle using Volo (Alt.) & Giratina to obtain +0.6× bonus points; Rei & Decidueye, Arc Suit Cynthia & Garchomp, or Paulo & Lycanroc to obtain +0.4× bonus points; and Cyrus & Palkia or any unlisted Ghost-type sync pairs to obtain +0.2× bonus points.

This event featured the Battle Challenge, where players were challenged to defeat a team of strong opponents. Players could complete event missions by clearing these areas with one or fewer sync pairs fainting and sync pairs with specific theme skills on the team. It also included a challenging battle against Volo (Alt.) & Giratina, where Giratina would begin the battle in its Altered Forme but upon taking damage that would cause it to faint, it would transform into its Origin Forme and have its HP restored.

For the duration of the event, a splash screen featuring art of Volo (Alt.) & Giratina was displayed when opening the game.

This event ran concurrently with the Challenge Arc Suits Event Show Me Thy Bonds.

Trivia

Unlike most battles, the Pokémon on the left and right sides in Challenge Volo do not have their own Trainers. Instead, Volo commands all three Pokémon.
This was the only event to allow players to obtain multiple of the same Special Skill Feather in a single run.
