You can use a Master Ball on a Regi, but it's not recomended. I caught 2 Regis with Ultra Balls and the 3rd one with a Timer Ball,which can be bought at the Pokemart in Rustboro, but first you have to talk to the guy you saved from the Aqua Grunt in the Petalburg Woods after you deliver the Devon Goods. He is found on Route 116 near the tunnel.
master ball
Well the best ball would be a ultra ball cause if u lower it with the move false swipe, u can catch a regi. this works wiith rayquazza too.
You can put it to sleep or freeze it
No it is not ok to use a master ball on zapdos ,use a ultra ball after you have weakend it.
no lower its hp then use an great ball
use an ultra ball and dont forget to put him asleep
you cant, you will need a master ball. I wasted mine catching Dialga yes u can use a heal ball i did it b4 im proved by pkmn master
use a master ball use a master ball
use action replay and get the code walk through everything
No but i have heard that you can use it like a master ball on latias
you should use it on lugia. he is the hardest one to catch. you cant catch him with any other pokeball. you can only catch him with a master ball.
its a trainers Pokemon so you cant catch it you can only catch wild Pokemon - awnser by softy312
use a master ball if you haven't got any u cant
First find it and weaken it. you cant catch it with full health unless you use masterball. Then, use either dusk ball or ultra ball.
You get it at level 50 at the whirl islands my advice is use as many ultra balls as you can then if you cant get it use a master ball.
When you get far enough in the game you will get a master ball, dont use it than even further in the game, there he is, that is when you use your master ball, cant miss, hope this help, but if you are to beat this game, you must fight dialga, hope this helped
you cant have to use action replay ds or if u have an r4 download cheats on it good luck
