Pokémon Sapphire Tips

Another way to catch Latias
Get a Wobbuffet to at least level 50 and/or another Pokémon with ANY move that can keep her from fleeing. Go to Route 120/121 and walk into the grass. Save here and walk around until you find Latias. Don't expect to catch her now unless you saved your Master Ball. Whittle her HP down a bit, and save again after the battle. (If you didn't find her, skip this step.) Restart your game and check your Pokédex for her. (If you didn't find her before, don't worry- you don't have to do this until you have done the previous step.)If she's in your area, look for her, and if you find her, repeat what you did the first time you saw her. If she isn't, restart your game and check your Pokédex for her. Keep restarting and finding her until you catch her. This works in Ruby (w/Latios), Sapphire, and Emerald (w/whichever one you picked).
