It can be if you want it to or you can use it on rayquaza, the easiest way to catch latios or latias without using the masterball is by having a Pokemon that has the abilites: Arena Trap, Shadow Tag and having the Pokemon be sent out first then weaken latios/latias then throw many ultra balls.
Yes
Master Ball.
yes unless you have a master ball latios is hard to catch
Latios, since rayquaza does not run away.
any ball just depends on how you weaken it and how lucky you are
Use your grand master ball on dragon ball z woop woop
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
no u hav 2 use a master ball sorry
it won't be fast or easy unless you have a master ball
I recommend the master ball
You have to fight it until its weak then use a master ball
well, I would save the master ball for latias/latios. so, use the timer ball. or just palin poke balls, like I did.
