The fourth Arceus Arc Celebration was a special battle event in Pokémon Masters EX celebrating the addition of the fourth chapter of the Arceus Arc to the main story. It was focused on the sync pairs Arc Suit Alder & Volcarona and Benga & Volcarona.

The "Alder Arc Suit Fair Scout" gave players an increased chance of recruiting Arc Suit Alder & Volcarona from the beginning of the event to June 9, 2025, and the "Benga Poké Fair Scout" gave players an increased chance of recruiting Benga & Volcarona from May 5 to 21, 2025.

This event featured event points, a currency that players could earn by completing battles. Players received rewards based on the number of points accumulated, including 5★ Scout Tickets, a Field 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 Alder & Volcarona or Benga & Volcarona to obtain +0.6× bonus points; Marshal & Conkeldurr or Iris & Haxorus to obtain +0.4× bonus points; and any unlisted Unova 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.

Additionally, the music and artwork on the title screen were different than usual. The title screen artwork depicted Arc Suit Alder & Volcarona and Benga, and the background music was Glorious Battle! (Alder) (Pokémon Masters EX Version). In addition, a special voice-over line of Alder or Benga saying "Pokémon Masters EX" would play as soon as the game's logo appeared on the title screen, chosen at random each time the title screen was loaded.
