The eighth Arceus Arc Celebration was a special battle event in Pokémon Masters EX celebrating the addition of the eighth chapter of the Arceus arc to the main story. It was focused on the sync pairs Arc Suit Misty & Starmie and Arc Suit Brock & Onix.

The "Misty Arc Suit Fair" gave players an increased chance of recruiting Arc Suit Misty & Starmie from the beginning of the event to March 14, 2026, and the "Brock Arc Suit Fair" gave players an increased chance of recruiting Arc Suit Brock & Onix from February 19 to March 14, 2026.

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 Tech 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 Arc Suit Misty & Starmie or Arc Suit Brock & Onix to obtain +0.6× bonus points; Blue & Pidgeot, Red & Snorlax, Leaf & Eevee, Milo & Eldegoss, Nessa & Drednaw, or Brassius & Sudowoodo to obtain +0.4× bonus points; and any unlisted Kanto 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.

From the beginning of the event, a splash screen featuring art of Arc Suit Misty & Starmie and Arc Suit Brock & Onix was displayed when opening the game.
