any ball just depends on how you weaken it and how lucky you are
yes unless you have a master ball latios is hard to catch
Yes
Master Ball.
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 have to fight it until its weak then use a master ball
I recommend the master ball
Master Ball which you can get at the (Team Magma or Team Aqua) hideout
You should save it for later to catch Latios.
you should do what ever you think is right try a quick ball
Ideally, the Master Ball is what you want to catch Latios/Latias, because their legendary status makes them difficult to catch. If not the Master Ball, I recommend the Timer Ball. The Timer Ball's catch rate becomes higher the longer the battle lasts. So, waste time in the battle (20-30 turns should suffice) and then throw a few Timer Balls.
In Pokemon ruby you can catch latios but not latias, in Pokemon sapphire you can catch latias not latios, in emerald you can choose. Use your master balls on them so they wont fly away. You can use other types of balls, eg timer ball, ultra ball, or great ball on the other legendaries.
Any.
