1. Ocelot in Metal Gear Solid 3. Any fan should see this as pure nerdgasm.
2. The Boss in Metal Gear Solid 3. Awesome music. Awesome story. Awesome atmosphere.
3. The End in Metal Gear Solid 3. Best sniper battle ever!
4. The Sorrow in Metal Gear Solid 3. Totally different in any way, and was a huge mind fuck.
5. Volgin in Metal Gear Solid 3. In my opinion, the best brawl in the whole series.
...Oh...
...
New list!
1. Metal Gear Solid 3 *Ahem*
2. Baldur & the last Joan fight in Bayonetta was damn epic. Everything a battle of super beings should be.
3. LUUUUU BUUUUUU at the gate in Dynasty Warriors 4. My friends and I have a theory that Lu Bu is the mightiest in the universe.
4. Palmer in FFVII. The fat fucker...
5. Ultros from FFVI. Heheheh, seafood soup! Does this make me a bad octopus?
Honorable Mention (Because even mentioning this battle makes all other boss battles inferior): God, at the end of Bayonetta. First, you ride a motorcycle at a 90 degree angle, up a rocket that sent God into space, dodging missiles and angels. Then, you summon a demon made from hair that is the size of Jupiter. With that demon, you then punch God through the solar system, into the sun, and then ride God into the atmosphere, turning her into a fine, snortable powder before she collides with the world.
You...you can't beat that!
