HP: 880

The Imp is both an enemy and a type of enemy (Imp-type). You can find them inside the Cavern of the Stolen Fayth. You need to capture five of each Imp-type enemy to unlock Vidatu in the Species Conquest section of the Monster Arena.

Imps are flying creatures, so have Wakka use his Blitzball attack to take them out. They are not resistant to any magic types, so have Lulu cast any spells on it that you like as an alternative to using Wakka.

Location
