Does AS or OR Have These Pokemon?

Question

I want these Pokemon, but I'm not sure which game they are in:

Latios
Spheal
Bagon
Onix(?)
Aron

So yeah, if someone could tell me if these Pokemon are in Omega Ruby or Alpha Sapphire, that'd be great.

Answer 1

Latios is in Omega Ruby, found at Southern Island, you could have also got him with the Eon Ticket event, but that is already over.
Aron can be found in Victory Road as a horde encounter, or in Granite Cave.

Spheal can be found in Shoal Cave.

Bagon can be found at the bottom floor of Meteor Falls. (If my memory is correct.)

Onix can be found in Granite Cave and some Mirage Spots.

Hope this helps!

Thanks! So really the only Pokemon that is different between the games are Latios and Latias.
