Trainers, attention! After appearing for the first time at the in-person GO Fest 2023 events in London, Osaka, and New York City, Diancie’s Mega Evolution—Mega Diancie—will make its worldwide debut for ticket-holding Trainers during Pokémon GO Fest 2023: Global!

We already know that Diancie is making a stellar appearance at the event, as part of the usual GO Fest exclusive Special Research quest lines, which will be available at every in-person event, and at the GO Fest 2023 Global virtual event.
Mega Diancie will be available through Mega Evolution, and it is expected that there will be special Research Tasks rewarding Mega Diancie Energy.
Mega Diancie is the second Mega Evolution to be announced for this year’s GO Fest events – we are also looking forward to evolving our first Mega Rayquaza! Mega Rayquaza will first debut in raids during the in-person Pokémon GO Fest 2023 events hosted in London, Osaka, and New York City!
London and Osaka in-person events are basically around the corner, and we really think you should start reading up on them if you are planning to go to any of those two. Here’s our recommended content for getting up to speed:
