As far as I know, hes not on any specific route, he wonders all around.
In kanto, on route 4. :-)
the Pokemon on the tv on Pokemon emerald version are latios and latias. If you say it was a blue Pokemon, you'll be looking for latios; if you say red you will find latias. Latios and Latias fly to different areas on the map. If, for example, a Latias is on Route 118, and you fly to Mauville, the Latias might move, this also sometimes happens if you are walking and then walk onto a different route. Hope this improved definition helps! 8)
No, you can only get Latias in Sapphire and Emerald and Latios in Ruby and Emerald.
you cant. You can only catch it in Pokemon emerald, but, you cant catch latias in emerald.
Anywhere.
Yep.
Ruby cannot capture latias only sapphire and emerald can.
you get latias and latios everywhere you just have to look very hard latias is mostly by slateport city and mauville city route 110,103. latios is mosty by forttree city and and lilycove city route 120,121,123.before getting latios and latias get a lot of ultra balls (save your master ball(s)!but you have to beat the elite four first to catch latios and latias.
Latias isn't in firered, it's in ruby, sapphire, and emerald.
You can find Latias and latios anywhere in Hoenn. You just have to get lucky.
One way is to trade with another emerald or you could trade your latias (or latios) to another emerald then restart the game and choose the opsite then catch it and trade back.
The only way to get a latios or latias in your Diamond or Pearl is to migrate, latios from Ruby or Emerald. latias from Sapphire or Emerald.
