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 the first 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.

In Generations II and III, a Trainer can use his or her Pokédex to check the ever-changing location of their 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.

Generation II

These Pokémon are found roaming Johto in Pokémon Gold, Silver, and Crystal; however, Suicune is found at the Tin Tower in Crystal. They can be captured at any point after they are disturbed by the player in Ecruteak City's Brass Tower.
