Sauron starts off this list with a very chic gold mask and red cape, a welcome alternative to the LAME dark grey uncostumed variant.

A quick jump past Sarumon and whatever was going on in Weathertop (neither of which had bosses of note to give disguises I guess), and we are met with this absolutely DAPPER octopus... thing? wearing a beautiful top-hat-monocle-fake-mustache combo.

Mines of Moria brings us a cave troll with a very pop-punk mohawk. These guys show up later but they all look like this fella so I won't place them all on this list.

Lurtz from Amon Hen looks the same so the next boss on our list is the Balrog (who did appear in Moria but the lighting is terrible in those cutscenes and you can't see the Balrog and his flowery goodness so the mountaintop battle will do). You look very bonita, Balrog.

The pride of the Nazgul fleet, the Dead Baron wearing his signature aviator helmet flying in to destroy two Hobbits. Overkill much?

The Dead Baron later fights in the Battle of Pelennor Fields which gives a better look at his uncostumed rider (how lame!).

The pride of the Haladrim fleet, the great Oliphants are seen wearing their signature baseball-best while riding into battle. Underkill much? Once again, these guys are later seen everywhere, sporting (get it?) the same baseball get up.

After a bunch of Two Towers levels with no boss disguises (almost as if nothing really happens in that movie lol), we begin Return of the King with that one chick's favorite sex icon. Shelob appears at the very end of The Secret Stairs but the fight at the beginning of this level gave a much better look at her goofy lil skates to screenshot.

This guy looks like he'd lowball you when you're trying to sell your car. This guy looks like he's not allowed within 100 feet of a school. This guy looks... like a sex offender.

She may not be a boss (that we fight at least; verdict still stands for the Witch-King's perspective) but she is costumed and she is on this list.

This is also the end of the list apparently. Really thought there would be a cool Sauron tower costume but The Black Gate and Mount Doom have no boss disguises!

I don't have any final thoughts I just really wanted to make this because whenever I tried to look up these images all that came up with this (equally interesting) gallery of the bosses from LEGO The Hobbit.

Thanks for looking at these images if you were curious.
