weaken it and put it to sleep
MasterBall
Use a masterball,parilize it,constently huck balls at it,damage it.
when you find that Pokemon if you have a master ball with you use a pokeball and you will capture it
You can catch Lugia when you get to the top of Citadark Isle. If you still have the masterball now is the time to use it. Then after you catch Lugia you battle Greevil and he has Torous, Exectutor, Rydon, Articuno, Zapdos, and Moltres. Hope I helped!!!
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.
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
try using dusk 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.
Ultraball, Duskball, and Masterball are your best choices. But sometimes, if the HP is low enough, it can be caught with a simple Pokeball even.
No.
Use something like mean look to keep it from running, then catch it like you normally catch a legendary.
