How do you catch latios and latias.I already watched the T.V and I picked..

1. You need somethin' with Arena Trap/ Shadow Tag. Trapinch and Wynaut and Wobbofet all have those effects. Weaken then throw a ball. If you haven't ran into them yet, you need to find them randomly. The other Lati you can get on Southern Island with a cheat or ticket.

2. Nintendo Events are where you get the secret tickets. They are NOT in the game so don't think for a second they are. You need to find where one is and they are only in the US of A. Ain't we lucky? ;)

They appear randomly. If you run into them, make sure you have a level 40 Woboffet in front of the line. His effect forces the Lati to stay in battle. It's Psychic vs. Psychic, so it may be hard. Good thing is, you might not faint as easily. Anyway, slowly wither down the Lati's HP, and make sure they don't use recover.

If you paralyze, freeze, or burn them, they can use refresh to stop that. So, put them to sleep when their HP is in the yellow/red zone using hypnosis. I reckon Woboffet knows it by now... Now, keep using ultra balls. You should catch them, eventually. Nintendo Events are special events taken place in famous places in the U.S. In order to go to one, go to www.pokemon.com and look at the happenings including pokemon.

The first one should be about a Nintendo Event. If it isn't, forget about it. But, if it is, select it and read it. It will say when and where it will be. Anyway... Nintendo Events give out special tickets, Pokemon, and items. Well, so I hear... I haven't been to one, yet. But, if you're not in the U.S. Or not even close to it, forget it.

If you use a golbat with mean look, the latios/latias can't escape.

You search around in the water or in the grass!!! Hope I helped

The only thing to do is play the game normally and youll find him eventually. Latias youll have to go to a nintendo event and get the eon ticket. Nintendo events are events sponsored by nintendo through which you can receive the ticket. However I'm not sure where the next one is or when.

You go to the route that has the bike path above it (i forget what it is called) and you have a pokemon that is at level 30 or less(no less that 20). you must also have repels. First you put on the repel and go to a patch of grass and run around for a while.

If he dosent show up then go into a house and right back out. Walk around some more(do not let the repel run out). Repeat process as often as needed.

I caught mine in a time of 5 minutes using this method. The reason for the entering and exiting is that every time you change a route, so will he.

By the way the pokemon you are looking for is latios.

Use max repel on a place with weak Pokemon like littleroot town so that only latios will appear. Nintendo events are events that are held to see future nintendo games & systems and stuff like that.

You can either use the Masterball you got (if you haven't used it already) or get a Golbat that knows Mean Eye. That way Latios can't escape. Then try to catch him.

Just keep on searching around for them and eventually you will find them. If you have alredy found it once you can go into the pokedex and look at area. It will show where it is. And when you do find it use a master ball( if you have one ).
Anyway I hope that helped!
