Use an ability or move which prevents escape, such as Block or Mean Look, and then lower its health/ give it a status ailment like paralyze, and procede in the usual way.
Yes
yes unless you have a master ball latios is hard to catch
you save it for latios because it is almost imposible to catch him without it
Master Ball.
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!
Either cheat or transfer it from a GBA game. You cannot catch Latios in the wild without cheating.
no
You have to fight it until its weak then use a master ball
I recommend the master ball
No, latios is very rare and it is stupid to do that you have to catch it with a master ball or cheat. If you useSleep Powder it will get asleep but go away anyway
Master Ball which you can get at the (Team Magma or Team Aqua) hideout
You should save it for later to catch Latios.
