Get the National Pokedex from the proffesser when you have seen 150 Pokemon
Here is how you get Latias and Latios In Pokemon Sapphire & Ruby
To get Latias and latios you have to beat the Elite four and when you are finish beating them up you are going to be in your house and then go down the stairs and watch the T.V. and they will say something about latias/latios what they are saying is that latias/latios is roaming hoen so you have to search the sea and the land to find latias/latios don't worry because they will be only in the olace where normal wild Pokemon appear if you have a sapphire version you need the Eon ticket to get latios or you can just ask your friend that has a latios to trade him to you and if you have a ruby version you need the same thing I mentioned before. happy catching!!!!!!!!Latias does not have a specific place in Hoen.I have a fiew tips on how do get Latias .First, if Latias is in your area use a repel or super repel.Why?Because it will only have an affect on the Pokemon that aren't Latias. Two, you need a Pokemon that that has an ability that won't let a wild Pokemon escape in battle.For example,Wobeffet that is the only one I know of that has that ability.You can also put it to sleep.It can still escape when poisand or paralized.Three.If Latias is not in your area you can always move in between routs till it comes to you area(see step 1,2). Latias only will come around Slateport to Ever Grand City only in that area,and all in between! Good luck. It also has the move Teleport, keep the in mind.
Actually I got latias in sapphire, First you need a Pokemon with block or mean look because it is hard to train wobbuffet.
Concluded n worked:
Most probably near Mawille city.
At route 118, thr's a small indent so make a secret base to go in n out of it, rather than changing routes or buildings, grass is jz outside, way more efficient.
Everytime u go out, check around 10 Pokemon encounters, then change,within an hour i assure u'll get it.
Last time i tried, only took me 1/2 hour, then i threw a master ball at it.You can get latias on sapphire, first you have have to beat champion which you probably already know next you got to go to the television in your house and it would say something about a flying red bird. That would be latias, the most common place it goes are above water and in the route under the bike road. I recommend using a masterball to catch latias because it's the only thing runs from you like crap.after you beat the elite four First, beat the Elite Four. Then watch tv. Then run around catching all the Pokemon that you skipped the first time. Eventually, you'll bump into Latias/Latios. Once you have seen her/him, you can find it via your PokeDex. You'll need a Pokemon with Arena Trap, Destiny Bond, or something to keep it from running. If possible, weaken it as much as possible w/o killing it. then throw balls like crazy. You'll get it eventually.
To encounter Latias/Latios after seeing it, go to the entrance to Cycling Road near Mauville. Keep going in and out of the door and checking your locator whenever you are outside. When the Pokemon is in your area, run to the grass and battle!
1. Defeat the Elite 4 2. Complete your Pokedex. 3. Collect all Battle Frontier symbols. 4. Defeat all Gyms; get all 8 badges. 5. Win a ribbon in all 5 of the Master Rank Pokemon contests. By the way, you can't go to space I think.
you have to train the Pokemon latios or latias till level 67 and talk to the guy in the space station ,he will take you to the moon .
if it did't work train it till 77 and try it again.
