weaken it confuse it and paralaze or poison or put to sleep to it and throw any pokemon a large amount of times then throw a timer ball
masterball
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.
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
you just need to get the master ball off the galactic grunt boss it has a 100% catch rate hope i helped or you can buy lots of ultra then go to terra cave (thats where find and weaken groudon down real low like about its about to faint but dont kill it then try to catch groudon with an ultra ball this will take patience.........lots of patience
A fleeing legendary pokemon
you can`t catch kyogre or groudon or both of them without linking them from sapphire, ruby or emerald version.
try using dusk balls
It really depends. If you aren't going to use your master ball on anything else, then using it on Groudon is fine if you want to. But you can catch it with a Poke ball or Great Ball, etc. Use dusk balls or ultra balls. It is not worth it to use masterball because groudon is not so hard. I caught groudon with only 3 ultra balls.
the strongest pokeball is the masterball. the masterball can catch any Pokemon out of the 493. it doesnt matter what kind of Pokemon it is, the masterball can catch any Pokemon.
No.
Use something like mean look to keep it from running, then catch it like you normally catch a legendary.
