Swarming Pokémon

Swarms, or Mass Outbreaks, have been a staple since the original Gold and Silver games were released and we find this game mechanic returning with HeartGold and SoulSilver. Unlike the originals, however, HGSS see a lot more swarms and as a result, many more Pokémon. There are a total of 21 possible swarms.

You may be pleased to know that all of Gold and Silvers swarm Pokémon have returned, though the version exclusiveness of Qwilfish and Remoraid has been foregone in exchange for some rarities from Hoenn. A comprehensive list, organized by route and then location, follows...
