While most trainers evolve Corphish into Crawdaunt immediately, the unevolved form has a niche with Eviolite boosting its defenses. Only weak to Electric and Grass. Part of the Gen 3 roster. Known as the Ruffian Pokemon.
Nothing fancy in Corphish's spread. It leans physical with Attack out front. And you'll get 1 Attack EV per KO for it. Follows a standard growth curve.
It came from overseas. It is a very hardy creature that will quickly proliferate, even in polluted streams.
Corphish Weakness
GoodElectric and Grass-type 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.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
