How to catch latios and latias on emerald?

Question

Do I maybe need an event?

Answer 1

Finish the game your mom will make you look at the tv and you say red or blue depends on what you will get the event is for the other One example you chose red then latias will be and latios in the event

Answer 2

As Megaswifter says, your TV choice decides which of the 2 you can catch. The other sadly, Is unobtainable without an event/trade.

When you do this, Latias or Latios is made available for capture. However, they can appear almost anywhere, in random encounters, and are very likely to flee. They behave similarly to the legendary beasts of Johto. Unfortunately (as far as I know) there is no way to track either of their locations, since they change randomly as you travel.

• They can even be encountered in Sea Routes while Surfing!

Answer 3

After you beat the game you will be at your house in littleroot town and your mom will see a report on TV and you will have to anser Red or Blue If that will give you Latias or Latios then
(I recomend having the acro bike for this) go to slateport city then go north untill the cycling road and there will be a patch of grass go into the patch of grass and get on your acro bike and put up a repel and hop on it (hop with B button) the acro bike hopping will not count as steps so you wont run into random wild Pokemon only latios or latias if hopping in the grass doesnt work try it for about 2-5 minutes still not working go into the cycling road house then go back out to reset it you have to keep trying until it works but it will it took me 30 something minutes but it will work though I hope I helped :)
