Warlock (Infinity Gauntlet) Amazing how everyone gives one character a massive advantage while the other is base form. Base form vs base form should be the question here. I would say that given the knowledge Apocalypse has he would teleport both of them to a universe other than Earth 616 to even the playing field as the Infinity Gauntlet would then be just a glove. Come on people balance these fights a little bit.

Deadpool Wolverine said in a comic "Deadpool is a far more efficient killer than I am"

Plus Deadpool's healing factor is not the issue here. It is better than Logan's but he is not as durable as Wolverine.

He does have a fast healing factor but the issue is that Thanos made it so Deadpool could never know the embrace of Death there by adding to the chance of the win.

Dr Manhattan (Watchmen 2009) This fight really depends on where the fight takes place. If it is anywhere other than Earth 616 in the Marvel universe then the Infinity Gauntlet is useless and it is Doctor Manhattan vs Base level Thanos in which Thanos is outclassed. If it is in Marvel Earth 616 then Thanos would win. My guess is that the fight would not take place there so I give this to Manhattan.
