Try using a Pokemon with the ability Shadow Tag or a Pokemon that knows Block that has higher speed than Latios/Latias. Then weaken it and use an Ultra Ball or some other ball. You can make it Sleep, Poisoned, Paralyzed, etc. to make it easier to catch too.
use a golbat that has mean look so that latias cannot escape.
You have to get it's health down to the lowest you can. if you kill it, it will come back later with full health. You should use ultra balls, you don't want to waste really good ones.
NONE!! Except for the master ball. i have heard that luxury ball can also be used like a master ball on latias comment but i have wobbufet as my first pokemon,then i found a latias,then i caught it with two ultra ball...
After you beat the Elite 4 in Pokemon sapphire, latias will be in the wild in random places. I suggest you keep a master ball because latias always runs away in battle when you incounter it.
Pokemon ruby/ sapphire/ emerald= latios/latias. Pokemon diamond/pearl/platinum=cressila.
Try letting it sleep Then throw a Master Ball.....I tried that and it actually worked
use you weakest Pokemon and hit his until his hp is half.and use perimeter ball or master ball and the highest ball and you will catch his be careful because you do not want to kill it.
a master ball!!!
LATIAS no doubt that's what they ment it to be for i think.
In the Aqua Hideout.
Right of Lilicove
In Pokemon ruby you can catch latios but not latias, in Pokemon sapphire you can catch latias not latios, in emerald you can choose. Use your master balls on them so they wont fly away. You can use other types of balls, eg timer ball, ultra ball, or great ball on the other legendaries.
The trick is to save your master ball.
you can get a master ball by winning the lottery in lilycove
