You can catch the shiny version of Regigigas in Pokemon GO, but only if you are very fortunate after winning a Regigigas Raid.
The exact odds of any Regigigas you encounter in Pokemon GO being shiny is 5%, or 1 in 20. This is the shiny rate for Legendary Pokemon in Pokemon GO.
The best time to catch a shiny Regigigas is during one of the Pokemon GO Regigigas Raid Hours. This is because the number of Regigigas taking place during both of these events is greatly increased.
Of course, the more Regigigas Raids you win, the more likely you are to find a shiny version. All you need is enough Raid Passes to take part in plenty of Raids!
