You mean "Latias" or "Latios", not lotias. You can only get Latios (blue) in Ruby, and you can only get Latias (red) in Sapphire. Both are level 40. After you beat the Pokemon League just walk around the whole region and maybe, eventually, one day you'll find a Latios. After you find Latios and try to attack/use an item you'll find that it flees. Its supposed to do that, so don't think your game is glitched up. After you found it look up its location ocasionally in your Pokedex and follow it to encounter it for another chance to battle.
