Yes, you can catch the shiny version of Cresselia in Pokemon GO, but only if you are very lucky.
After winning a Cresselia Raid, there is a low chance that the Cresselia you encounter will be the shiny one.
If you are after a shiny Cresselia, by far the best time to get one is during the Pokemon GO Cresselia Raid Hour. This is because Cresselia Raids will be taking place much more frequently during this event.
How to Catch Shiny Cresselia in Pokemon GO
To catch shiny Cresselia in Pokemon GO, you must first win a 5-Star Cresselia Raid. Then, you have to hope that the Cresselia you encounter as a reward for beating the Raid is the shiny version.
Unfortunately, you have to rely on luck for this, as there’s no way of guaranteeing that the Cresselia you encounter will be shiny.
Cresselia Shiny Odds
The odds of Cresselia being shiny in Pokemon GO are 5%, or 1 in 20. This means that, on average, you will encounter one shiny Cresselia for every 20 you encounter.
1 in 20 is the standard shiny odds for all Legendary Pokemon in Pokemon GO. Therefore, Cresselia has these shiny odds too.
What Color is Shiny Cresselia?
The shiny version of Cresselia retains the light yellow head, neck, and stomach of the standard version but swaps out every other color.
Shiny Cresselia has a purple body, green wings, teal paws, and a teal marking on its head.
