after u beat the elite four.
after that, someone at the battle frontier will tell you about latias and latios. then, latias will start roaming kanto.
In pokémon Ruby and Sapphire Latios or Latios start roaming Hoenn after you beat the Elite four. The place you meet them is random - but someone say that if you have a bigger chance of catching Latios in route 119, and Latias in route 110. In Pokemon Emerald, one of them starts roaming Hoenn after you beat the Elite four, and you tell your mom what colour it was on the Pokemon they mentioned on the TV. Red gives Latias, blue gives Latios.
When you knock out a roaming Pokemon, it will faint and then start roaming again, but with its health at full.
There are Contests, completing the Pokedex, Latios is roaming the wild (Latias if you have Sapphire) and of course you can migrate your Pokemon to Diamond, Pearl or Platinum and start an entirely new game. Hope this helps! :D
I got Squirtle and the Pokemon that was roaming around was Raikou. I caught it after he was roaming about for a while I battled him a lot of times. By the way! You don't get legendary dogs in original Red, you get them in Fire Red only.
Special*. Bulbasaur*. And to answer your question, you get Entei, the fire dog pokemon, roaming around Kanto region AFTER you defeat the Elite 4.
After you get the lost doll from the fan club at vermilion city, Steven talks to you about latias(heartgold) latios(soulsilver). After that, latios/latias will start roaming the kanto region. You can see where it is in your pokegear
start with squirtle beat the elite4 and it will be roaming wild
Yes in fact you can. To start roaming latias get the clefairy doll from the man in vermilion and step out the door and latias will roam. To get latios, you need to get the enigma stone from wifi.
After you capture/defeat heatran they start roaming sinnoh
first you have to go go to olivine city you have to go to cherrygrove city and battle 100 pidgeys in a row if you don't get them all in a row,you have to start over. so i would say, after you battle 1 pidgey save your adventure, then once you battle 100 pidgeys in a row, you go to the elete four, and walk around in the Pokemon center only around the edges, then you talk to nurse joy and she will give you latios!!!
Grodonobtanable rare pokemon-latios(blue at start of game)latias(red at start of game),kyorge(marine caves)groundon(terra cave),rayquaza(sky pillar) latios,latias random areas (after elite 4)
