Klingon criminal who fled imprisonment in 2364 by causing the destruction of the cruiser T'Acog and hijacking a Talarian ship, the Batris.
Korris, along with his accomplices Konmel and Kunivas, apparently crippled the Batris during their takeover, and were the only survivors rescued by Enterprise-D personnel from the Batris just before the Batris exploded. Kunivas died shortly thereafter.
Korris and Konmel were later killed when a second cruiser was ordered to return them to the Klingon Homeworld. (Heart of Glory [TNG])
