Pokémon Masters EX has added Chapter 10 to the Arceus Arc, continuing the game’s latest major storyline alongside a wave of new content. To celebrate, the Arceus Arc Celebration Special Battle Event is now underway through August 24, 2026, at 10:59 p.m. PT, giving players the chance to participate in special battles and earn a variety of rewards. Also now live is the limited-time Diantha Arc Suit Fair, which introduces the new 5★ Arc Suit Diantha & Gardevoir Sync Pair. Arc Suit Fair-exclusive Sync Pairs feature powerful Arc Suit Passive Skills that strengthen allies and manipulate Type Rebuffs when entering battle, while also debuting the new Multi Role, allowing them to excel offensively or defensively depending on their characteristics.
