Pokémon outbreaks (Japanese: 大量発生 mass outbreak), also known as swarms, mass outbreaks or wild outbreaks, are a feature introduced in Generation II that allows the player to catch Pokémon that are usually rare or otherwise unobtainable. They appear in every generation after their introduction except Generation VI.
Pokémon outbreaks originated in Generation II. In that generation, if the player registered a certain Trainer in the Pokégear, that Trainer would occasionally call to tell the player that he saw or heard about a large number of Pokémon in a certain area; for the next 30 minutes after such a call (in real time, not play time), the swarming Pokémon would appear in the given area with much greater frequency than the usual 1%.

In Generation III this method allows the player to catch Pokémon that cannot be caught normally and makes rare Pokémon temporarily more common.
The player may view televisions in houses to see if and where an outbreak is occuring. Outbreaks are determined randomly each day and last for 24 hours. During an outbreak, the swarming Pokemon will have an appearance rate of 50%.
The record mixing feature of Pokémon Ruby, Sapphire, and Emerald allows players to give an outbreak they've seen to other players, regardless of whether that outbreak would naturally occur in the player's game. The traded outbreaks will be announced on television in the following days after mixing records.
Pokémon outbreaks were largely expanded in Generation IV. Once the player attains the National Pokédex, every day in a particular location, a "swarm of Pokémon" appears, which changes the probability of finding the given Pokémon from 0% to 40%. Outbreaks last only one day and are random events. Information about Pokémon outbreaks can be found in Sandgem Town by talking to Lucas/Dawn's sister or by watching the Sinnoh television DPPt, or by listening to Professor Oak's Pokémon Talk HGSS.
When players all join the same group, they will all experience the same outbreak on any given day.
The species of an outbreaks seems to be determined using a formula, because it is not chosen randomly when the player starts the game that day. It is also possible that the species is determined the day before, though there is no additional evidence to support this. If the DS clock is changed or a different DS is used, then the game will detect this and will not change the species swarming until 12:00 AM.
Due to higher catching rates for Pokémon that appear during outbreaks, they make longer and better chains when using Poké Radar.
The feature also appears in HeartGold and SoulSilver, where all the wild Pokémon available include all those that were available in Generation II, Ditto, Chansey, and Pokémon from Hoenn and Sinnoh. Information on swarms can now be found by listening to Professor Oak's Pokémon Talk on the Pokégear radio.

Unlike previous games, the Pokémon outbreaks can be manipulated by soft resetting the game: turning the console off without saving the game beforehand, but only if the player has not saved their game at all that day. When the game is restarted, there will be a different Pokémon swarming.
During winter, the monitor may occasionally not report on outbreaks, which is due to parts of Route 8, where Croagunk can be found, becoming frozen during Winter and not allowing the Pokémon to be caught there. All have the level range of 15-55.
All have the level range of 40-55 and encounter rate of 40%.
