Use something like mean look to keep it from running, then catch it like you normally catch a legendary.
Yeah it is possible to catch kyogre with out wasting your masterball you wont have to use it until you see latias and latias requires you to use your masterball.
EVERY Pokemon is able to b caught WITHOUT a masterball....... if you know a Pokemon will flee (latios/latias etc) have wobufett as your batteler so they cant escape.....Silph co.
You find Latias randomly in the wild on every route on the left side of the map. To make it easier to catch use repels. If youre pokemon are under level fifty latias will appear. If you didn't use your Masterball on Kyogre I recommend you use it on Latias.
You can get Latias? Oh right! Use a masterball for a guarantee catch, if you are a button masher use any pokeball.
yes but only on ruby or safia
It can be if you want it to or you can use it on rayquaza, the easiest way to catch latios or latias without using the masterball is by having a Pokemon that has the abilites: Arena Trap, Shadow Tag and having the Pokemon be sent out first then weaken latios/latias then throw many ultra balls.
weaken it and put it to sleep
you can, the catch is fairly easy even without a masterball although I woul use ultra balls if you arent going to use a masterball. I you knock out reshiram without sAVing before hand you can try again after the credits at dragonspiral tower
A fleeing legendary pokemon
No. You should use your masterball on a wandering legend like Raikou, Entei, or Latias.
get all 8 gym badges and profeser elm will give you a masterball and you can find lugia in the whirl islands and you need a silver wing
you cant stop her you have to catch her and you have to use a masterball
