How do you get a latias faster than waiting for it to show up ?

You can't it shows up eventually, always be prepared for it. It only appears after the elite 4 remember.

You dont.... Just keep checking your map and you might run right into it. Don't try to chase it down. And especially don't use fly.

I recemend that you go buy Max Repel's and use them while your searching for Latias. It helps you running into her faster.

Well, if youve seen it once you can track it in your pokedex. But if you havent seen it at all then you have to just wait

Try using an action replay or a gameshark.

Every time you teleport,move routes,fly,go to a different town it changes places 2 so b rdy for it 2 appear what I did was went to route 117 and kept goin in and out the day care and using max repel and running in the grass cause you're not changing locations

You have to follow it instead of waiting for it to show up. Keep an eye on your map. It should show the location of Latias. Every time you move from one zone to another, it will as well. Be sure you have something to trap it in battle with.
