How do I get latios?

First you have to defeat the Elite Four and the Champion. After it you appear in your room and when you get out of the house you'll see your dad. He'll give you a ticket and after he leaves you'll receive a news flash of a blue pokemen flying across Hoenn. Then it's a matter of luck since it's location changes everytime you enter or leave a house, go to other route...But you can always see his location on your pokedex. I suggest then after it you use a Pokemon with Mean Look or Sleep Powder cause latios will escape almost everytime. Good luck now!

1. Beat the Elite Four
2. At home go downstairs and when your mom and dad are done talking to you, click on the TV and it will say that a blue Pokemon is flying around
3. You might have to have a level 80 Pokemon or higher, I am not sure but it has worked 3 times
4. Go to pacifidlog town and surf to the left and look around for about 3 or 4 Pokemon and if he doesn't show up, go to the right side and do the same thing
5. Repeat this and you will likely find LATIOS(AWESOME)
Good Luck!
