Everthing in bayonetta and Shadow of the Collosus.
Yes, I have an epic boss battle fetish too.
Oh and Lost Planet 2.
I was gonna name Lost Planet 2 as well but then I figured that its more like youre the epic one in those boss fights, since enjoyment varies with how good you are at it.
I remember beating the supposed insane difficulty in like 3? hours.
In MetalGearSolid 2, against the many Metal Gear Ray, and the final battle against Solidus. And it was hard as hell.
In Devil May Cry 3 both of the battle against Vergil.
And the various Kratos fight of God of War Saga
Also this
Was pretty epic for me the first time i played it.
I should say.. God of War 2... battle with zues...
I would say it's safe to say most of the boss battles in the God of War series were pretty fucking legit. Remember Cronos in God of War 3? One of the best moments.
-Kessler from inFAMOUS on hard mode(Please someone back me up on this)
-Terumi from Blazblue continuum shifts true ending(Actually, I dont need to list why. Anyone who loves Blazblue enough to play it already knows).
-Yazmat from Final Fantasy XII(Oh my fucking god. That is all).
Kessler was a bastard on Hard Mode. Took my ass down at least 20 times.
Terumi is just an asshole.
Yazmat...did not make it far to fight him, but I did fight the Hell Wyrm.
And the final battle on Heavenly Sword was pretty epic as well.
fighting yazmat was like trying to kill the hand of god. That fight, LITERALLY took me 5 hours of nonstop nerve wracking scrapping & bare survival, only to have it victory stolen from me at the absolute last second. & I did this fight over 17 times. I wanted to rip that little moogle into fur clumps.
For me the most Epic/Hardest Boss Battle would have to be Alatreon for Monster Hunter Tri, that is if you tried to kill him without being cheap and sleep bombing him and try to slash him to death. He was such a bitch to fight so many times I would die from just two hits but fun none the less.
another one of my favorite boss battles was ganon on windwaker. i love it when he turns around and smacks the crap outta zelda for shootin him with light arrows, and when he kicks you in the face when you try to block his combo, lol (i don't remember it being that hard of a battle tho).
Kinda recent but I really did like fighting Sonic Generations Death Egg Robot battle. That remix music as well. Really fun to play imo along with the original Death Egg Robot :)
