A former, brilliant Klingon military strategist, Korrd spent his emeritus years on Nimbus III as a diplomat. In 2287, Korrd fell under Sybok's influence and joined the Vulcan zealot on his quest for Sha'Ka'Ree.

A drunkard, Korrd played a critical role in using Captain Klaa's bird-of-prey to rescue Captain Kirk from Sha'Ka'Ree.
