John Colicos as Kor was slated to be the recurring Klingon adversary for Kirk, but he notified that he was unavailable for "The Trouble With Tribbles". Then, he was supposed to play Kor in "Day of the Dove", but was again unavailable.
According to Memory Alpha
Koloth was meant to be a recurring character. In fact, I've often wondered if in Trials and Tribble-Ations Dax's comment about Koloth regretting never facing Kirk in battle was a reference to those plans falling through.
