Your favorite 'last boss' battles

Marauder shields from mass effect 3

Fable 2s last boss was epic. I loved it & no im not being sarcastic. It was beautiful & i wish more boss battles were like it.

Also I liked Duke Nukems old boss battles from DN 3D, & i liked the boss battles from Deus Ex HR

Zhao in Deus Ex HR

Shao Khan in MK

Darth Malak KOTOR

Darth Traya in KOTOR II

RAAM in Gears

The Joker in Batman AA

The Boss in MGS 3

Most memorable is Ganondorf from Zelda OoT. Loved that fight as a kid.

God of War is the Pandora Box of Boss Battles.

Giygas from Earthbound (SNES)

Ganon from The Legend of Zelda (NES)

Glados from Portal (Xbox360)

Mundas from Devil May Cry (PS2)

Off the top of my head:

-Aforementioned Mother Brain
-Emperor Ing/Dark Samus combo at the end of Metroid Prime 2
-Ares from the original God of War
-King K. Rool in Donkey Kong 64 (Funny as hell, very creative)
-Yami from Okami (Don't see this one brought up often, and it's absolutely amazing)

Dead Space, Mass Effect 1/2 & Batman Arkham Asylum (against The Joker).

1) Planescape Torment (PC) - The Transcendent One - Definitely my favorite "last boss" battle, just by the sheer genius and varieties in which you can deal with him. I defeated him through pure conversation...and not only that, it was one of the most intense and interesting final boss confrontations I've ever experienced in a game. How many games can claim to give you the option to defeat the final boss through pure conversation, and still have it be one of the most interesting final boss confrontations you'll encounter.

2) Shadow of the Colossus (PS2 / PS3) - Malus aka the Sixteenth Colossi - Huge and towering...this final boss isn't just a "boss"...he's basically a level, and an epic one at that.

3) The Legend of Zelda: The Wind Waker (Gamecube) - Fighting alongside Tetra / Princess Zelda to take down Ganon - I've always enjoyed the final boss fights of the Zelda games, but what sets the one in Wind Waker above the rest and allows it to be among my favorites is this is the first time that Princess Zelda aka Tetra is fighting alongside you the whole battle. Sure, she's controlled by the computer, but it gave a whole new dynamic to the fight and her, instead of the cliche damsel and distress that we had seen Nintendo Princesses adopt before. Instead, Tetra / Princess Zelda in Wind Waker is more then willing to fight right beside you two-to-two with Ganon the whole time, and it's her teamwork plan that allows you to deliver the final blow to take him out.

4) The Legend of Zelda: Ocarina of Time (N64) - Ganon - At the time, it was a big epic boss to cap off a big epic game.

5) Serious Sam: The First Encounter (PC) - Ugh-Zan III - Huge and over-the-top.

6) Doom (PC) - The Spiderdemon - Most here may be too young to remember this or not even know what I'm referring to...but at the time, The Spiderdemon was one bad mofo in a game that revolutionized gaming at the time.

7) Metroid (NES) - Mother Brain .

8) Diablo II (PC) - Diablo - Something about finally encountering Diablo in Diablo II felt epic.

9)Portal (PC) - GLaDOS - an entertaining final boss.

Radec in Killzone 2

GUN had a cool last boss.

Ocarina of Time even tho it was too easy.

I see two mentions for The Mother Brain from the original Metroid. How could I forget about that epic fight? Time to dust off the old NES and fire this baby up!

-I enjoyed the Bane Joker battle at the end of Arkham Asylum

-Zoran Lazarevic was a good fight in the end of Uncharted 2.

Mundus from DMC1

Jeez guys, you ever heard of spoiler warnings? Wouldn't be too surprised if this thread get's closed ^^

So, spoiler for Wild Arms 2:

The Lord Blazer Battle, though not difficult (the actual "real" final boss is a battle before him, so this is more like a philosophic battle), it's just amazingly good made, the music is an epic orchestrated version of the standard main theme of the game, cutscenes that really get your emotions to the fullest and a nice battle mechanic as well as setting.

You could also play Metroid: Zero Mission, which is basically an excellent remake of the original Metroid.
