Pokémon Masters EX has added new missions to the Ultimate Battle stage Two Finest Subway Brothers, giving players additional challenges to complete in the mobile strategy game. The update went live on Oct. 12, 2026, at 11 p.m. PT, and the new missions have no time limit, allowing players to attempt them whenever they are ready. The Ultimate Battle is part of the permanent Challenge the Strong content in the Side Area and features some of the game’s toughest battles, requiring carefully assembled teams and well-developed Sync Pairs. Players are encouraged to improve their Sync Grids, unlock Lucky Skills and upgrade their gear to prepare for the challenge. To access Challenge the Strong, players must first complete Champion Stadium Hard Lv. 1 for any region, while attempting the new missions requires completing Main Story Chapter 1, The More the Merrier, on Normal difficulty in single-player mode.
