My Pokémon Ranch explaining the general mechanics of a mass outbreak

Mass outbreaks (Japanese: 大量発生 mass outbreak), also known as swarms, Pokémon 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 from Generations II to V, in Pokémon Brilliant Diamond and Shining Pearl, and in Pokémon Legends: Arceus.

In the games

Generation II

In Generation II, if the player registered a certain Trainer in the Pokégear, that Trainer occasionally calls to tell the player that they saw or heard about a large number of Pokémon in a certain area. Until midnight (in-game time), the swarming Pokémon appear in the given area with much greater frequency than the usual 1%. Only one swarm can appear per day. The player can force a particular swarm to appear if a swarm has not already appeared that day by first deleting all possible phone numbers except the swarm Trainer's and then repeatedly toggling Daylight Savings Time by speaking with the player's Mom in New Bark Town. There is a 50% chance of triggering a phone call every time DST is changed.

Generation III

In Generation III, in addition to making rare Pokémon temporarily more common, this feature can be combined with record mixing to allow the player to catch Pokémon that cannot be caught at all normally. Pokémon encountered through mass outbreaks will also have a predefined set of moves.

After entering the Hall of Fame, every time the player wins a battle, there is a ~0.5% (328/65536) chance that the game will generate an outbreak; this does not apply to link battles, e-Reader battles, the Safari Zone, or the Battle Tower/Frontier. After an outbreak is generated, the television program announcing it will appear the next day. Once the television program has been watched, the outbreak becomes active.[1] Once outbreak has been activated, it will last until the end of the next day - during this time there's a 50% chance the game will generate the swarming Pokémon instead of using the usual encounter table (effectively halving the encounter rate for non-swarming Pokémon). However, seemingly due to an oversight, once a particular savefile generates an outbreak, it will never generate another one outside of record mixing.[2]

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.

Generation IV

Mass outbreaks were largely expanded in Generation IV. Once the player attains the National Pokédex and has entered the Hall of Fame, a "swarm of Pokémon" will appear every day in a particular location, which changes the probability of finding the given Pokémon from 0% to 40%. Outbreaks last only one day and are random events. Information about mass 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 outbreak seems to be determined using a formula, because it is not chosen randomly when the player starts the game that day. Even if the date is edited, the next swarm will always be the same. 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.

Pokémon Diamond, Pearl, and Platinum

Many of the Pokémon obtained through mass outbreaks are outside of the Sinnoh Pokédex, and are usually otherwise exclusive to other regions.

Due to the high encounter chances for Pokémon that appear during outbreaks, they make for longer and better chains when using the Poké Radar.

Generation V

The gates in Unova have a monitor inside that will alert the player to where an outbreak is taking place.

Unlike in previous games, mass outbreaks can be manipulated by soft resetting the game, 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.

Black and White

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 found there. All outbreaks in these games have a level range of 15-55.

Generation VIII

Pokémon Brilliant Diamond and Shining Pearl

A mass outbreak in Pokémon Brilliant Diamond and Shining Pearl. Of note is the Corsola appearing in the tall grass.

Pokémon outbreaks return for the first time since Pokémon Black 2 and White 2, featuring the same encounters as in Diamond and Pearl.

Unlike in Generation IV, the Pokémon featured in the mass outbreaks appear in the top grass, popping in and out en masse. These Pokémon cannot be interacted with, however, and the means of encountering them remains the same as in the original games.

Pokémon Legends: Arceus

Pokémon Legends: Arceus has two types of outbreaks: mass outbreaks and massive mass outbreaks (Japanese: 大大大発生). Prior to v1.1.0, only mass outbreaks were available. Outbreaks can be seen on the Hisui map when choosing where to travel. They are indicated by a circle with the headshot of a Pokémon (for a mass outbreak) or a question mark (for a massive mass outbreak) over an area.

De/activation% Outbreaks per area Spawns per outbreak
Mass outbreak 20% 1 10-15
Massive mass outbreak 25% 11-15 Wave 1: 8-10 Wave 2: 6-7

In a mass outbreak, many Pokémon—from the same evolutionary line—spawn in a single location. Only a single mass outbreak can be active in an area at a time, but multiple areas can have a mass outbreak. In total, a mass outbreak will spawn 10 to 15 Pokémon before ending, with 4 Pokémon being spawned at any given time. A new mass outbreak may activate any time the player returns to Jubilife Village, at a 20% chance per area; when leaving the village, there is also a 20% chance an outbreak will deactivate per area, except for the area the player is traveling to.[3]

In a massive mass outbreak, many mass outbreaks (11 to 15) occur in an area. Massive mass outbreaks draw on their own set of mass outbreaks that has some overlap with species seen in normal mass outbreaks, but also many unique species. Initially, each outbreak location is only visible as a question mark; they can be revealed by visiting each location or by giving 5 Aguav Berries to Mai's Munchlax (near the area's exit). When revealed, some locations may be highlighted by a yellow circle, with either a Berry or a star marking it. A star indicates that that location has extra waves to its outbreak. A Berry indicates that each time a Pokémon from that outbreak is defeated or caught, the player will receive one Aguav Berry. There may be zero or multiple locations with a Berry or a star (but never with both). Each outbreak location has a 10% chance to be a Berry location, but only if it is not a starred location.

If a location in a massive mass outbreak initially has a star, then it will spawn Pokémon in two waves. After clearing all Pokémon in the first wave, a second wave will spawn with Pokémon that are either evolved versions of the original wave (with a small chance for any to be an alpha Pokémon), one of the species from the first wave but always as alpha Pokémon, or both (i.e. evolved versions of the original wave, all of which are alpha Pokémon). If the second wave consists of evolved versions, the map icon for the location will change to reflect this; either way, however, the star will remain present on the map during the second wave. A cleared location that does not have a Berry or star has a chance to nonetheless produce a second wave as though it did have a star.

All Pokémon found in massive mass outbreaks will be at least level 60, unless the Pokémon's species is one that evolves starting at some specific level, in which case non-alphas of that species will be found 1-3 levels under the level required for evolution.

Massive mass outbreaks last for a limited time after the player arrives at the containing area. They may start with 7, 9, or 11 minutes of time. As the time wanes, the game will display a warning at certain intervals.

Time remaining Message Start point chance
0 minutes The rainstorm seems to have ended. --
1 minute The rainstorm seems like it’s about to clear up. --
2 minutes, 30 seconds The rainstorm may go on a bit longer. --
5 minutes The rainstorm shows no signs of stopping anytime soon. --
7 minutes 75%
9 minutes 15%
11 minutes 10%

Pokémon in outbreaks have increased chances of being Shiny. For example, with the Shiny Charm (and therefore all research task bonuses), wild Pokémon have a Shiny rate of approximately 0.17%, Pokémon in a mass outbreak have a rate of 0.78%, and Pokémon in a massive mass outbreak have a rate of 0.46%. For full details, see Shiny Pokémon → Legends: Arceus.

The Pokémon that can appear in each area in outbreaks are as follows (mass outbreak and massive mass outbreak are abbreviated as M.O. and M.M.O., respectively, Pokémon marked with an * only spawn in massive mass outbreaks of their pre-evolution or from a second wave):

The majority of Pokémon species in Hisui can have a Mass Outbreak in the region(s) where they normally spawn in the overworld, with the exception of five categories:

  • Pokémon species that never appear in the overworld (Mythical and Legendary Pokémon, Sneasler, Overqwil, Hisuian Electrode, etc.);
  • Pokémon species that appear exclusively as fixed Alphas in the overworld (such as Infernape, Torterra, Empoleon, Rapidash, Dusknoir, etc.);
  • Pokémon species that appear exclusively in the Space-Time Distortions (starter lines, Eeveelutions, Magnemite line, Johtonian Sneasel line, Cranidos and Shieldon lines, etc.);
  • Pokémon species that exclusively appear flying in the overworld (Togetic, Togekiss, Hisuian Braviary, Magnezone, Crobat).

Also, Pokémon that normally spawn only during the day or at night in the overworld can have an Outbreak at any time of day, such as Drifloon or Zubat that normally only spawn at nighttime, but can outbreak during the day as well.

Two Pokémon have additional requirements for appearing in Massive Mass Outbreaks:

  • Spiritomb will not appear until all 108 Wisps are obtained and Request 22: "Eerie Apparitions in the Night" is complete.
  • Unown will not appear until all 28 forms have been found and cataloged in the Unown Research Notes.

A mass outbreak of Pikachu in the anime

In Ivysaur's Mysterious Tower!, Vermilion City was the site of a mass outbreak of Bulbasaur and Ivysaur. Ash and Goh learned that the former grassland, now the site of a new Gym, was the ideal site for the Bulbasaur line to absorb the solar energy and wind needed to undergo evolution.

In Gotta Catch a What?!, Ash and Goh ventured into the mountains to discover a reported Pikachu outbreak. They learned that Pikachu had gathered because the area was rich in Thunder Stones, helping the Pikachu, including Goh's newly caught one, evolve into Raichu en masse.

In Trials of a Budding Master!, Goh learned of a mass outbreak of Geodude at the Rock Tunnel. After arriving there with Ash, he almost immediately found one and caught it.
