What Pokemon will I have to encounter in Pokemon Ruby&Sapphire?

Question

I want to know what Pokemon do I have to encounter. Like the Snorlax in Pokemon Firered/Leafgreen.

Comments

Did you mean Pokemon you have to encounter in the overworld? Like how the Snorlax is blocking your path?

I think the asker means what Pokemon are you forced to encounter.

I'm pretty sure the only wild Pokemon you need to encounter are Kecleon and either Kyogre or Groudon.

Answer 1

As sumwun already told, the only wild Pokemon you are forced to encounter are the Kecleon on Route 120. The second one is either Groudon (Ruby) or Kyogre (Sapphire) in the Cave of Origin. The rest of the encounters are only optional.
