Roaming Pokémon

Roaming Pokémon are a type of legendary Pokémon that, instead of remaining in one place as a special event, run around the region they appear in, seemingly at random. Roaming Pokémon have appeared in every main series game since Generation II.

In addition to their changing of routes (something that happens every time the player passes through a route boundary), they will also, on every turn of battle, attempt to flee. The only way to prevent this is to either use a trapping move such as Mean Look or have the Pokémon sent out have a trapping ability such as Shadow Tag or Arena Trap. If they try to flee and fail, they attack on the same turn.

In Generations II and III, a Trainer can use his or her Pokédex to check the ever-changing location of their target after they have seen the target. However, in Generation IV, the Pokétch's Marking Map application and the Pokégear's map card serve this purpose, relieving the player from having to change through a multitude of screens, as was the case in past generations.

List of roaming Pokémon

Generation III

Hoenn

The Eon Pokémon can be caught in Hoenn after defeating the Elite Four for the first time. Only one will roam Hoenn (the other can be obtained on Southern Island with the Eon Ticket), depending on version, or in Emerald, depending on the color of Pokémon the player tells his or her mother. In Ruby and Sapphire Versions, the roaming Pokémon will have low IVs due to the Roaming IV glitch.

Kanto

These Pokémon are only present in Pokémon FireRed and LeafGreen. The only one that will appear will be the one whose type weakens the type of the player's chosen starter Pokémon (Raikou for Squirtle, Entei for Bulbasaur, Suicune for Charmander). They will have low IVs due to the Roaming IV glitch. If they use Roar to flee, they will disappear due to the Roaming Roar glitch.

Torunerosu will only appear on Pokémon Black Version while Borutorosu will only appear on Pokémon White Version.
