Any Pokémon is catchable without the Master Ball, though some-especially Legendaries-are harder than others.
Catch Groudon.
you get a master ball from someone. use it. he's AWESOME!save your master ball for latios use an ultra ball to catch groudon that's what i did and it worked
you can if you have a Master Ball
you can use master ball in caught the groudon
weaken it, make it sleep and use many ultra balls it will work eventually.
you can with ultra balls or if your stupid waste your master ball-PS i caught groudon with a heavy ball (he weighs more than two thousand pounds) so that might be to him a master ball
You should save it for later to catch Latios.
Not unless you trade it. Sorry.
no
I'm not quite sure what your talking about, but I would have to say that you would not have to catch it in a Master Ball.
In order to catch your legendary Pokemon in Pokemon Sapphire, save your master ball For Rayquaza...you can catch KYogre/Groudon/both with either an Ultra Ball or Timer Ball.
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.
