timerball
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.
Latios is a legendary Pokemon in Pokemon Emerald. It can be caught with an Ultra Ball, although it is not very likely unless the player has managed to whittle down its HP and affected its status in some way.
yes unless you have a master ball latios is hard to catch
Well, without one its kinda hopeless, but , if you get it to its lowest health,and use alot of ultra balls, it'll give in, and you'll catch it!
If you have already beaten the elite four and have Latios or Latias already roming around in emerald then you can chase it down till you are in the same vicinity as it and go into the grass to see it appear. toss a master ball at it and you will have the latios or latias. Of course it's best that you clone the master ball first so that you can catch the other one the same way.
Yes it can, it would be easier to catch Registeel with a Ultra Ball than with a normal PokéBall.
Yes
Master Ball.
yes but it is hard and you have to be lucky
any ball just depends on how you weaken it and how lucky you are
yes try making it asleep and it will be easier or any status problems
Latios ways a few more pounds making it easier to catch with the Heavy Ball. Also, Latios has 20 more Base Sp. Attack than Latias (130 in total), whereas Latias has 20 more Base Sp. Defense than Latios(130 in Total)A comparison from Psypokes:LatiasHP80ATK80DEF90SA110SD130SPD110LatiosHP80ATK90DEF80SA130SD110SPD110
