Karis Tatenen

Karis Tatenen was a 23rd century male native to the planet Khepri. By the late 2240s, Tatenen was serving as a command division officer in Starfleet, assigned to the USS King Richard. He became famous across the Federation in 2248 after his brave deeds against several Klingon battleships during the Battle of Vonra, and was labelled as the "Destoyer of Klingons".

By the late 2270s, an elderly Tatenen had risen to the rank of fleet admiral and was one of the oldest officers in active service at that time. (SS TOS (The Blaze of Glory))
