Easy way to catch Latios
First get alot of max repels 99 to start. Second get a lvl 39 wobbuffet and a bit higher lvl wobbuffet like 50-60 third go to route 101 use a max repel and wal run or ride a bike through the grass untill you get latios make shure you have alot of great or ultra balls mabey even time balls they would preaty well. Being that wobbuffet has the skill (shadow tag) latios can't escape. This methed works because latios in the whild is lvl 40 and max repel repels Pokemon that are a lower lvl that you have set as your first pokemon. It may take awhile but trust me this methed works. The heigher lvl wobbuffet is for back up incase your lvl 39 wobbuffet faints. Good thing is when you get in a battle you will know that it is latios as long as you have a max repel on.
