Pokémon GO Hydreigon event — exclusive move

Niantic is giving Pokémon GO players until 9:00 p.m. local time on Saturday, May 16, to evolve Zweilous into a Hydreigon that knows the exclusive Charged Attack Brutal Swing, according to event listings and game guides. The move is tied to the game’s Deino Community Day Classic, which ran from 2:00 p.m. to 5:00 p.m. local time and left a four-hour evolution window afterward. Pokémon GO Hub’s weekly event roundup and Deino Community Day Classic guide both say the bonus applies worldwide in local time. A 2022 Pokémon GO post from the official game site shows the same event rule for Deino Community Day, with Hydreigon learning Brutal Swing when evolved during the event window or the extended period afterward. ### What exactly do players have to do before 9 p.m.? Pokémon GO players need to evolve Zweilous before 9:00 p.m. local time on May 16 to receive a Hydreigon with Brutal Swing, according to Pokémon GO Hub’s May 2026 event listings. That means players must first have enough Deino Candy to complete the evolution line — 25 Candy for Deino to become Zweilous and 100 Candy for Zweilous to become Hydreigon, Pokémon GO Hub’s guide says. (pokemongohub.net) Hydreigon’s featured attack is not listed as a normal always-available reward in the event guide. Pokémon GO Hub says Brutal Swing is the Community Day move for Hydreigon and is learned only when the evolution happens during the event hours or the post-event grace period. ### When did the main event end, and what is still live tonight? (pokemongohub.net) Saturday’s Deino Community Day Classic ran from 2:00 p.m. to 5:00 p.m. local time, Pokémon GO Hub said in both its weekly calendar and dedicated guide. The same sources say the evolution bonus continues until 9:00 p.m. local time, which is the remaining live portion relevant to players who already caught Deino or built up Candy during the event. (pokemongohub.net) The official Pokémon GO site’s June 2022 Deino Community Day announcement described the same structure: a three-hour event followed by up to five hours in which evolving Zweilous granted Hydreigon with Brutal Swing. That older post does not cover the May 2026 event directly, but it matches the mechanics cited in current 2026 guides. (pokemongohub.net) ### Is this only for one city, or is it worldwide? Pokémon GO Hub describes the May 16, 2026 Deino Community Day Classic as a global in-game event that runs on local time. That means the 9:00 p.m. cutoff applies separately in each time zone rather than at one single worldwide hour. Palo Alto players can take part the same way as players elsewhere by evolving in-game before their local deadline. (pokemongolive.com) The user-provided local reference points to Pokémon GO Hub’s event page for area-specific planning, but the event itself is not limited to California or any one in-person venue. ### Why are players targeting Brutal Swing Hydreigon? (pokemongohub.net) Pokémon GO Hub’s Hydreigon database page lists Bite and Brutal Swing as the recommended moveset for the Dark- and Dragon-type Pokémon. The same page lists Hydreigon’s maximum CP at 4,098 and says the Pokémon is especially weak to Fairy-type moves. Pokémon GO Hub’s event guide identifies Brutal Swing as a Dark-type Charged Attack with 55 power in Trainer Battles and 65 power in Gyms and Raids. (pokemongohub.net) Those figures are part of the reason the move is treated as the key reward from the event, according to the guide. ### Where can players check the remaining details tonight? (db.pokemongohub.net) Pokémon GO Hub’s “Pokémon GO Events This Week: 11–17 May 2026” page lists the Deino Community Day Classic schedule, including the 2:00 p.m. to 5:00 p.m. event hours and the 9:00 p.m. evolution deadline. Its separate Deino Community Day Classic guide includes the Candy requirements, the featured move details and the move’s battle power. (pokemongohub.net) Saturday, May 16, is the last date in those listings for players to secure a Brutal Swing Hydreigon through evolution. After 9:00 p.m. local time, the event pages do not list another same-day window for that exclusive move. (pokemongohub.net)
