I played pokemon ruby years ago and as far as I can tell latios is a roaming pokemon, that means he may be anywhere in the region. Also he can flee from battle and he usually does in the first turn so if you want to catch him i recommend catching a pokemon with 'arena trap' such as Trapinch, this will prevent him from fleeing (I cant remember if Trapinch is in ruby or not) or you'll have to use a master ball or rely on shear luck.
Latiasyou cant find latias in Pokemon ruby you can only find it in sapphire. in Pokemon ruby you get latios no, you get latias in ruby and latios in sapphire because of the colour, Latias is red means ruby,latios is blue so means sapphire. your right above me but you got it mixed up. No its latias in sapphire and latios in ruby trust me i took forever trying to catch latias in sapphire and i finally did.
It is posable to get a shiny Latios in Pokemon Ruby but the chances of getting it is even more rare then just getting a shinny pokemon. If you are able to get one you are one lucky person
As soon as you defeat the Pokemon league, you can find Latios roaming around in the wild. You can also get Latias in Pokemon Sapphire.
You can get the regice, regirock, or registeel.
