Two Bosses Enter ... but only One Boss Leaves, in WoW Insider's series of fantasy death matches. This season's bosses come from the five-man instances of Wrath of the Lich King.

With two matches under our belts already this season, it's time to lay out the season's preliminary lineup of bosses from Wrath of the Lich King's five-man instances. Two Bosses Enter, One Boss Leaves is our series of fantasy death matches between the game's infamous PvE villains.

The central tenet of a Two Bosses matchup is an assumption that the bosses are of approximately the same level and health. It's fighting abilities and style we're debating here – so don't get caught up in actual game mechanics. Consider the flavor each villainous gladiator brings to bear, and cast your vote for who you think would come out on top.

Join us after the break to see the first round of pairings for this seasons' five-man Wrath boss death matches.
