A fight between the following in a semi-barren wilderness (mostly flatlands with a few wooded areas), 5 km radius. Just the hero, any summonable minions, and their usual equipment, they know about each-other's presence and are looking to kill each-other.

King Arthas (post-corruption Lich King, end of Frozen Throne)
Infested Kerrigan (Queen of Blades, end of Brood War)
Warden Maeiv (Sentry, end of Frozen Throne)
Prince Kael (Blood Elf Leader, after he turned to Illidan & the Burning Legion for magic)
Gul'dan (from Warcraft II, at the height of his power)
Lothar (another Warcraft II hero, also at the height of his power)
Zeratul (post-Brood war)

This is so Zeratul it's not even funny. I don't know too much about the WC3 heroes (other than they suck, they're stupid arses, etc) but I doubt any one of them has detection abilities. Kerrigan is the only one who can give Zeratul a run for his money, and only if she can cast psi storm on his position, or somehow cast ensnare.

Zeratul on the other hand is permanently cloaked (at least when in combat), and has a massively damaging "warp" blade - 100 damage every slash.

Of course, the scenario is flawed - WC3 heroes have more hitpoints and never die (as long as you have an Altar of the Kings or somesuch). By game mechanics Zeratul will have to constantly hacking and slashing the WC3 heroes who will keep on getting reincarted.

Though on the other hand, if you accept "realistic" conditions, an invisible warp blade to the neck will sever it. Without any way of detecting said invisible weapon and it's wielder, Zeratul beheads everyone - with the exception of Kerrigan, who can cloak (though it drains her energy). I still think it's a duel to the death between Zeratul and Kerrigan. My money's on Zeratul. He's lived longer. He's like Starcraft's Yoda.

I would say Uther, actually.
