Corphish cannot be caught in this game. It must be traded in from a compatible game where it appears in the wild. On GBA, cross-region trading unlocks post-game after Celio's Sevii Islands Ruby & Sapphire quest. The Switch re-release supports only one-way transfers out to Pokemon HOME.

How to Get Corphish in FireRed & LeafGreen

Nothing in FRLG fishes up Corphish. Route 102 fishing in Hoenn produces the crawfish in all three Gen 3 games, so trading from any RSE save supplies one for Kanto.

Corphish Weakness

Electric and Grass moves hit Corphish for super-effective damage. The Water typing picks up 4 resistances to work with. Corphish's physical bulk (base 65 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
