Found drifting in the S.S Botany Bay by Captain Kirk and crew, Khan and his band of super-humans outsmarted and out muscled the Enterprise crew and gained control of the ship. If not for a double-cross that saved Kirk's life, Khan would surely have been the future ruler of the Universe. But it was not to be, Round 1 to Kirk.
The rivalry would be renewed many years later as Khan escaped exile on Seti Alpha 5 (no, I did not have to look that up), hijacked a starship and hunted Kirk down for vengeance.
I won't ruin Star Trek II: The Wrath of Khan for you but suffice it to say that Round 2 went to Kirk as well. Although only because Mr. Spock sacrificed himself to save the ship and crew - "That was hell of a thing when Spock died" (Seinfeld fans know what I'm talking about here).
Why This is a Great Rivalry
First of all, William Shatner vs. Ricardo Montalban - it doesn't get much better than that. This one had it all - decades of pent up hatred, stolen space cruisers, vengeance, and wrath - lots of wrath.
This little piece of video should provide you with a pretty good idea of what this rivalry was all about:
