I'm not 100% sure i'm thinking of th correct person when i think of bane, but nonetheless I think he would have a slight upperhand on this 1.

Matching brains (not 100% sure).
Fett's mando training vs Bane's pure power... I give it to Bane, i mean he is a Force Tank.
Boba has my respect, but Bane just overpowers him in too many ways.
Only reason id say Boba has a chance, is due to his arsenal and ability to stay alive in dire situations.

Obi-Wan Kenobi or Anakin from Episode III wouldn't stand a chance for instance.

Wow that was very convincing if he could beat Yoda then i think Boba would lose but i reckon Boba could beat Mace. In a tales comic it says only a handfull of people could beat Boba in hand to hand combat. Can anyone else help me give reasons why Boba might atleast draw ?

I would imagine the handful of people were trained in Echani or Mandalorian methods.

Assuming "Hand-to-Hand" doesn't mean the force.
Which it probably doesn't seeing as the context was with Han Solo.

Vaders peak was more around episode 3 then before episode 4...after he lost his limbs and padme, he ws just an empty shell, Bane learnt from Revan and A Lot of other powerful sith lords, Vader had palpatine yes but i would also like to add that Darth Krayt gets Banes holocron...not Vaders and i do believe Krayt was alive during Vaders reign...Fett it was nice knowing ya but Bane would crush him. Also Bane wasnt the only one considered the Sith'ari, there was also the Zabrak whos name escapes me right now.

I have a few things to add.

Well first I was gonna say about the Sith'ari thing but I didn;t want to make a mistake and I couldn;t be bothered to go get my copy of Path of Destruction to check. And secondly thats the reason I won' tell you the name of that Zabrak.

As for the Holocron well, I think ol' Krayt was probably not as learned as he would have hoped, seeing as if he wanted eternal life or whatever surely he should have used a holocron belonging to Plagueis?

Also he wanted to talk to Bane cos similarly to his Vong infection Bane had suffered that obalisk thing.
And the Vader Peak thing. Between III and IV. For Sure. Maybe around... 8 BBY or so?

As for Bane's advantages well he was a supreme master with a lightsaber he would have easily defeated the likes of Mace Windu and probably Yoda. He was also a master of the dark side. Think Luke (circa Betrayal) only on the dark side. On the first day he learnt Sith Lightning I would imagine it was Palpatine standard. He used the dark side to survive when powerful (really powerful) poison was in his system (killing him. He was also no physical pushover. Due to years in the Cortosis mines he was massivley strong like "World's Strongest Man" strong, it would take an awful lot to knock him off his feet even without the force.

Plus as many of you say in a lot of these things "Depends if Boba got the drop on him"

You can't "get the drop" on the dark side of the force.

This reminds me of a quote from Tales Of The Jedi The Sith War: "Technology, no matter how deadly,is no match for the force"
(So what I'm basically saying is stop going on about the EE-3 and junk, this is about skill not weaponry.)

"The Outcome-----Hangs in the air"

if Fett had both EE-3 and pistol w/ stock he would probalby win.. Bane would be to arogant with his "im more powerfull than u" and "the dark side will destroy u" sith type stuff.

Bane learnt not to be arrogant after his tussles in the Sith academy.

and like ummm someone said earlier. Bane was believed to be the chosen one in his day.

He coulda given a Vader at his peak a run for his money.
