Heroic Anub'Rekhan :o
My favourite boss in Naxx all time since i played WoW is Sapphiron. Everyone hide behind that Fake iceblock now!
Loatheb for sure!
Easily Sapphiron; his assembly animation is really cool and then he also has a pretty awesome design in general.
Always liked Anub'Rekhan. Nax was the first raid I ever did and seeing this giant beetle guy ready to wreck your face is one hell of an intro to WoW raiding.
I would say Maexxna simply put the hardest boss so far and you aren't able to win without an astonishing and fast combo.I 'm waiting to see sapphiron and kel'thuzad until then Maexxna is the boss!
Faerlina and her OP hero power
Heroic Maexnna
I like Gothik, myself. The two sides thing is fun when soloing.
Gluth was always my favorite because it was my job to snare & kite the adds away from everyone. <3
Loatheb
Heigan the Unclean for me, that boss brings a good memory back of laying on the ground dead watching one healer and one dps kill him by them self from 80% there other 8 of us lay on the ground dead.
My favorite boss in Naxx is Maexxna. That's because one time back in WotLK when Naxx was still relevant, my guild was at her door, getting ready for the pull. While they were waiting, I pulled out my Crashin' Thrashin' Racer Controller and ran around in circles. Turns out that it can aggro NPCs, though... and Maexxna ended up kicking its ass, then started kicking ours. Luckily, we managed to kill her, and I even won The Jawbone for my Death Knight. I get the giggles every time I fight Maexxna in WoW or Hearthstone.
My favourite is Kel'Thuzad. Definetely. Master of mages! :D
Patchwerk. Still the purest form of raid boss there is, and the measure against which all others must compare against.

My favorite fight is Heigan. No matter how old the fight gets, there're always a few players who die on the dance :)
Patchwerk is by far the best!
Maexnna most def
I still love to this day, Gothik the Harvester. Being separated into two groups even during 40 man was scary enough to have half the resources you were depending on. Constant wipes made him a pain but when he came down from his perch you got such a resolve to push at him and beat him for the night. And when you did it was both enthralling and disappointing, because you would stand over his body but then down the hall was one of the worst Naxx had to offer. The Four Horsemen.
