What is Enigma Week in Pokemon GO?
By Jack O'Dwyer

What is Enigma Week in Pokemon GO? It's your chance to encounter some of the most legendary Pokemon in-game long after the GO Fest event concludes.
Niantic Labs' annual Pokemon GO Fest tradition continues with Ultra Unlocks. Every year, trainers are faced with global challenges that they all must work together to complete. For every eight challenges completed, Niantic provides them with a week-long event happening later that year. The first Ultra Unlock was Dragon Week. The second, and more popular, is Enigma Week.
We can confirm that Trainers are encountering Victini, the Victory Pokémon, when completing their #PokemonGOFest2020 Special Research! Is Victini’s appearance tied to the arrival of Team GO Rocket? Trainers, see here for more details: https://t.co/lyCuDVdTlJ pic.twitter.com/coHQ1E4C4A

It's no wonder as to why trainers are clamoring about Enigma Week. After completing 16 global challenges, Niantic has unlocked the opportunity to encounter Deoxys this August.
From Aug. 7 at 1 p.m. to Aug. 14 at 1 p.m., trainers will be able to find powerful "mysterious" Pokemon such as Bronzong, Claydol, Bronzong, Elgyem, and Unown U, L, T, R, and A in raid tiers one through four. In five-star raids, Deoxys will be appearing with a shiny chance.
Additionally, Cleffa, Igglybuff, Lunatone, Solrock, and Elgyem will hatch more frequently from 7 k.m. eggs while Staryu, Jigglypuff, Clefairy, Lunatone, Solrock, Baltoy, Bronzor, and Elgyem will appear more frequently in the wild. Staryu will be available with a shiny chance for the duration of the week.
More information about Enigma Week and other Ultra Unlocks during Pokemon GO Fest are available on Niantic's Pokemon GO blog.
