Two bosses enter... but only one will get to leave in our series of fantasy deathmatches. Over at WoW Insider HQ, we've selected some of the most dangerous bosses to be found in the World of Warcraft today, and now we're pitting them against one another in a fight to the death where only one can be champion. And the best part of all this fun? You get to pick our winner! That's right -- after reading up on each boss, your votes and comments will determine who goes on to the next round and whose lifeless body gets a victory screenshot.

This week we're looking at Prince Malchezaar from Karazhan and Hakkar the Soulflayer from Zul'Gurub -- and before you balk that Karazhan and its inhabitants are much more difficult than those in the lower-level Zul'Gurub, I must remind you that the rules of our little game mean we attempt to consider these bosses on equal footing. That means they're both going into this fight with approximately the same level, health, and damage ability -- what we're debating here is how they fight, not which one has the most hit points.

If we've piqued your interest, keep reading for a rundown of each bosses' mad fighting skillz!
