Montalban Khan. Unarmed fight.
Worf obviously loses, to show that Khan is a menacing, scary, threatening dude. It's pretty much his job description.

Going by the Abrams movie, Vulcans are noticeably stronger than Klingons, and Khan was overpowering Spock pretty decisively and would have almost certainly won if not for getting phasered in the back, so don't see how Worf fares better here

and honestly I don't remember the Montblanc version having any feats whatsoever to go on, he picked up Chekov at one point fairly effortlessly so he's clearly meant to be superhuman strength wise but other than that there wasn't anything I recall to go use for a rumble
