Can you catch Johto or Hoenn Pokemon?
Considering Ruby and Sapphire has all the Hoenn Pokemon, they’re not included in Fire Red and Leaf Green aside from Deoxys and two others (see below). While all of the Kanto Pokemon barring Mew were included, only a handful of the Johto Pokemon were added in these games, all of them only available in the wild once you reach the Sevii Islands. The remaining Johto Pokemon can be captured in Pokemon Colosseum.
