Pokémon GO Fest 2026 will focus on Mega Mewtwo X the most anticipated Pokémon. The creature appears as the main raid boss and as a loot in the brand‑new ‘Genetic Mastery’ quest. Players can freely choose the X form or the Y form, triggering debate over which is more powerful. Eurogamer outlined the Y form’s weaknesses and top moves earlier. The event runs without tickets, allowing the fest to all players without hassle. A Times Square Mewtwo display earlier this week drew pushback; Niantic has issued a clear official response.
