Best boss

I gotta say Dark Bowser.He's Bowser,Fawful with their dark power combined,witch the only way is Dark Bowser swollows Spider fawful to crate the ultimete boss.Bowser fights Dark Bowser and makes Spider fawful come out of D Bowser's stomach and then Bowser swollows Spider Fawful so Mario and Luigi can fight S Fawful.He's Awsome!

SERPHIOTH
or
TABUU
Or
Xenmas

In terms of difficulty, I'd have to say Jemima from Clock Tower 3. Length is topped by either Yami(Okami) or Melbu Frahma(Legend of Dragoon). Best boss sequence goes to Meta-God(Shadow Hearts) and Yunalesca(Final Fantasy X), and overall, throughout the whole game awesomeness....KEFKA XD

Yeah...I like a lot of bosses...

Well, for the most difficult boss, I'd have to say, the Lingering Sentiment from Kingdom Hearts II Final Mix+ But, my favorite boss of all time is Liquid Ocelot at the end of Metal Gear Solid 4. Coolest boss fight ever.

Easiest i'd say was the final battle in sonic chronicles:the dark brotherhood
A hard one is Richter is TOS2:Dawn of a new world

Yunalesca was one hard boss and Kefka is one crazed person

In Difficulty of bosses i would say the hardest boss i ever fought in a game would have to be Seprioth Kingdom Hearts 1

I agree Layle. It took my brother forever to beat Sephiroth.
