Every month, Pokemon GO has a new selection of Mega and Legendary Raid bosses to battle, and May 2023 looks to be pretty exciting!
This month features the debut of a brand-new Mega Pokemon, a new shiny Legendary, and the return of some fan-favorite Bug-types as Raid bosses!
The following Mega and Legendary Pokemon will be available to battle in Tier 4 or Tier 5 Raids at certain points during May 2023:
- Tapu Bulu
- Mega Slowbro
- Genesect (Shock Drive)
- Mega Scizor
- Tapu Fini
- Mega Pinsir
- Mega Altaria
If you want to catch any of the Legendary Pokemon in Raids, the best time will be during the May 2023 Pokemon GO Raid Hours. Each Legendary Pokemon gets at least one Raid Hour, where Raids featuring it will be much more frequent!
