The Pokémon Go Ultra Space Wonders event, running from May 23 to May 28 at 8:00 p.m. local time, marks the unofficial end of the World of Wonders season of content, which officially ends on June 1. And this event closes the season with a bang, introducing Naganadel, Stakataka, and Blacephalon to the game, along with improved spawns for many other rare Pokémon. If you're planning on taking on the various Ultra Beasts and attempting to complete every bit of free and paid research available, here's a look at the tasks and rewards you'll have access to.
The main draw for the Ultra Space Wonders event is the Timed Research of the same name, which will cost you $5 or the equivalent in your local currency for the Research Ticket. It includes more encounters with Mareanie, who makes her first appearance as a Shiny in this event, bonus items, and an exclusive Naganadel Wings item for your avatar.
The final page of the seasonal World of Wonders Special Research is also available to complete, which will net you 100 Poipole Candy and some other goodies upon completion. This must be done before it ends on June 1st.
