How do you catch latios in Pokemon sapphire
There are many Pokemon you catch that are similar in sapphire and emerald but there are many Pokemon emerald can only get and not sapphire.
NO!
you can`t catch kyogre or groudon or both of them without linking them from sapphire, ruby or emerald version.
Catch it in route 116
you can't catch it in any version
Yes, Pokemon Sapphire version is the version in which you can catch Latias. You can only find it once you have beaten the Pokemon League, then there is a report of a legendary red flying Pokemon in Hoenn. Latias appears randomly.
Sadly, you can't catch Groundon is the Sapphire Version, however you can in the Ruby version, you will find him in the same place you find Kyorge in the sapphire version.
You can't: you can only get it in a trade from a person with either Pokemon sapphire version or emerald version.
jump on a bike and eat its tail
Can't. You can't but if your friend will give you 1 from other version you can have 1 :)
You can't catch Exeggcute on Pokemon Sapphire. You need to trade one from Fire Red or Leaf Green.
