Pokemon Go List of New Raid Bosses May Edition, Shiny Included

The Legendary Lake Trio Azelf, Mesprite, and Uxie are the new Regional Legendary Raid Bosses in Pokemon Go, and as now reported by the Pokemon Go community, players around the globe will have a chance to battle and catch new Tier 1-Tier 5 Raid Bosses.
The Raid Boss’ pool has changed once again and new Raid Bosses are now available to battle and catch. The following Raid Bosses will most probably stay the same until May 27 (when Legendary Lake Trio leaves Raids), so if something changes, you’ll be the first to know.
Now, let’s take a look at what’s new:
Tier 1: Duskull (can be shiny), Drifloon (can be shiny), Shuppet (can be shiny), Shinx (can be shiny)
Tier 2: Pineco (can be shiny), Exeggcutor, Sneasel, Mawile (can be shiny), Misdreavus (can be shiny)
Tier 3: Sharpedo, Machamp, Gengar, Scyther (can be shiny), Alolan Raichu (can be shiny)
Tier 4: Absol (can be shiny), Alolan Marowak (can be shiny), Shiftry, Houndoom, Tyranitar
Tier 5: Azelf (Americas and Greenland), Mesprit (Europe, Middle East, Africa, and India), Uxie (Asia-Pacific Region)
Most of the players were hoping to see Lapras as part of the new Raid Boss pool, but it seems like Niantic is saving this Pokemon for a new Water event this summer and hopefully they will bring it back to Raids.
For last, and as now confirmed by Niantic to Reversal, the Legendary Trio will not be rotating after May 27. This means that a new Raid Boss will join us after the Lake Trio.

Don’t lose your hope, Niantic also confirmed that Azelf, Mesprit, and Uxie will be available in the wild after the event, but with a smaller spawn rate.
