Preaty simple just mention some of your most memorable boss fights in any game you have played
First ones to come to my mind are:
1)The last boss from Maximo,the total darkness room is incredible
2)The last boss from ZOE2 it was so fast yet ran so smoth it was awesome
If this has been posted before sorry.
My favorite was probably Ganon in Zelda 64 (OoT).
However using the Diety Mask on the boss of Zelda 64 MM was a LOT of fun!
…man, I need to get Windwaker…
Mantis (I think that’s it) from the Metal Gear Solid (not sure, think it is) game; the thing that read your memory cards and generally freaked you out.
The Egg from Saga Frontier 2. I like a good challenge.
The last boss from Arc the Lad 2…he was a challenge too.
Zeromus(FF4) was always a challenge for me.
The Black Dragon from Chrono Cross was pretty cool too (i liked the actual waking up part).
Also, I can’t neglect mentioning Magus with his cool-ass battle music.:fungah:
Zelda 2: Adventure of Link.
After the bird, you encounter none other than…
Yourself?
Ruby Weapon from FF7.
In Mischief Makers, trying to get all the gold gems from the bosses was quite an ordeal. (To get them, you have to beat each of the bosses without getting hit. And while most of the bosses ain;t too hard on their own, THIS was a bitch.)
THAT is something I will never forget.

Can’t argue with that, mantis was a classic enemy.
Others that stick in the mind are…
That bastard tyrant on the plane from ressi Evil: Code Veronica (I cheered no end when I finally killed him)
Ash at the end of the GBC pokemons. What a twist.

Hee ^_^, I’ll have to agree with you on that!
0_0, you don’t have Wind Waker? You should get it! The final boss in that game is definitely one of my most memorable boss fights!
Also, when you fight the Sinistrals in Lufia 2. I’ll never forget that.
Hiruko in Shinobi on Super Mode. Best 12 hours of my life.

Amen. Psycho Mantis was indeed a classic. But I have to say the fight with Ocelot just because of everything that happens following the fight. 
Shaher from Tactics Ogre -KoL. It seemed sooo hopeless in the beginning but thanks to Rictors “Ignis Fatuus” I finally did it. p:unch::
And the two vampires from Illusion of Gaia… I was never able to beat them… sob
Dragon Tank - Chrono Trigger
Magus - Chrono Trigger
AtmaWeapon - Final Fantasy VI
Siren - Final Fantasy V
Ultimecia - Final Fantasy VIII
Ultima Weapon - Final Fantasy VII
Metal Gear RAY - MGS2SOL
The final boss in Earthworm Jim; just getting to the boss and taking down the… ahem… was cool enough, but then you get to the boss itself, and you have to keep a straight shot while spinning around and around on a platform.
The Mad Doctor fight in Contra: Hard Corps. You stand in a laboratory, as the doctor splices combinations of enemies together, and you fight them off. It’s unique. Also in Hard Corps, the fight against the afro fish-guy with the Castlevania whip.
