August 2021 has lived up to the hype after July was one of the biggest months in Pokemon GO history.

The yearly celebration, Pokemon GO Fest, took place in the middle of the month and we also had the fifth anniversary of the game, which Niantic has thrown an event for. Now, we move into the final Ultra Unlock bonuses players earned at this year's GO Fest.

All of this means there are set to be plenty of raid boss changes for players to get stuck into.

So, with that in mind, here are all of the current Pokemon GO Raid Bosses that are active in August 2021 that will be coinciding with Ultra Unlock part 3.

One-Star Raid Bosses

GO Fest is now in the rearview mirror, and players earned a bunch of bonuses during the event, and therefore, Raid bosses have once again changed. You can find the One-Star Raid Bosses below:

  • Galarian Farfetch'd
  • Galarian Slowpoke
  • Galarian Zigzagoon
  • Unown U

This information is correct from August 20 and will be updated when the Raid Bosses change again.

Three-Star Raid Bosses

Alongside the One-Star raid bosses, the following Pokemon will be available to battle in Three-Star Raids.

  • Galarian Weezing
  • Lapras
  • Machamp*

*Note - Falinks was originally due to appear in Three-Star Raids, however, due to a bug, it has had to be replaced by Machamp. It will still be available in the wild, however.

This information is correct from August 20 and will be updated when the Raid Bosses change.
