Event pokémon, also known as Eventmon, are pokémon that are found via special conditions. Some of these conditions include:
- Specific days of the week.
- Specific times of the day.
- Having a specific item.
- Entering certain contests. (EX.: The Wish Jirachi contest)
- Participating in certain events. (Ex.: Easter Events, Halloween Events, Special occasions such as 11/11/11)
- Buying DP items / pokemon
They do not appear in the results of Mapdex searches because they are not normal, every day pokemon.
