Shiny Pokémon have different odds depending on which scenario you can encounter them in. During events, such as Community Day or 1-day limited events like Research day, your chance to find a Shiny Pokémon are greatly increased: 1 in 10 Pokémon, or 1 in 25 should be shiny. A similar story happens with Legendary Pokémon as well, where 1 in 20 has the chance to be shiny. The table below shows shiny odds in different scenarios.
| Scenario | Shiny odds |

| Base chance | 1 in 500 (0.2%) |
| Medium chance | 1 in 125 (0.8%) |
| Permaboost | 1 in 64 (1.6%) |
| Community Day | 1 in 25 (4.0%) |
| Legendary | 1 in 20 (5.0%) |
| Day event | 1 in 10 (10.0%) |
