Pokémon GO Fest 2026 will centre on Mega Mewtwo X the most anticipated Pokémon. The creature appears as the primary raid boss and as a loot in the fresh ‘Genetic Mastery’ quest. Players can easily choose the X form or the Y form, triggering debate over which is more powerful. Eurogamer outlined the Y form’s counters and top moves earlier. The event runs without tickets, opening the fest to all players without hassle. A Times Square Mewtwo display earlier this week drew negative reaction; Niantic has issued a prompt official response.
