Finneon is an uncommon and colorful fish found in the rivers of Sinnoh. It's a hardy fish, and one of a relatively small number of new Water Pokémon in Diamond and Pearl, and has a variety of useful Water-type moves, among others. Perhaps most intriguing, though, is its Storm Drain ability – this ability can be a powerful strategic boon in two-on-two Pokémon battles. Send Finneon out with a Fire- or Ground- type Pokémon, and any Water-type attacks will only hit the fish for minimal damage, protecting the other. Just hope they don't have a Grass-type on hand, too.
Evolves into Lumineon at Level 31.
