Dynamax Regirock appearing in Max Battles

Dynamax Regirock is live in Pokémon GO Max Battles this week, giving local groups a new Power Spot boss to fight and catch through Saturday, April 26. (pokemongohub.net) Pokémon GO Hub’s weekly schedule lists Dynamax Regirock in Max Battles during the April 20–26 event window, with the week running from 12:00 a.m. local time on Monday to 11:00 p.m. local time on Sunday. (pokemongohub.net) Niantic says Max Battles happen at select Power Spots, require at least one Max Pokémon in your battle party, and allow up to four Trainers to join the same fight. Successful clears award items and a chance to catch the boss. (niantic.helpshift.com) A Pokémon GO Hub event guide says Regirock’s featured Max Monday ran on April 20, 2026, and marked the debut of Dynamax Regirock in the game. The same guide says the battle costs 800 Max Particles, which are only consumed on a win. (pokemongohub.net) Max Battles work differently from standard raids because they are tied to nearby Power Spots and local groups, not the broader remote-raiding system Niantic added in 2020. Niantic’s help pages describe them as neighborhood encounters built around Max Pokémon, Max Particles, and in-person coordination. (niantic.helpshift.com (pokemongolive.com) That makes Regirock’s arrival part of a wider April schedule that has leaned heavily on Max content. Pokémon GO Hub’s April calendar lists Dynamax Regirock alongside other featured Max Battle bosses and weekly rotations across the month. (pokemongohub.net) Niantic also says Max Pokémon use special Max Moves that can be trained with Max Particles and Candy, including a defensive shield move and a healing move for allies. Those mechanics matter more in harder Max Battles, where survival and team support can decide whether a group finishes the encounter. (niantic.helpshift.com) For players deciding whether to make time this week, the short version is simple: Dynamax Regirock is available now at local Power Spots, and the current weekly rotation ends on April 26.
