I'm going to say not too many. He seems to be overpowered by each council member he faces with the exception of ki-adi-mundi (in the old star wars clone wars cartoons.)
I don't have good knowledge on all of these characters, so i'll start out like this: He loses at LEAST 1, 2, 8, 9, 10, 11, 12, 15
Maybe more. He could keep up with sabers against 8,9,10,12 and POSSIBLY 15, but he gets owned by everyone who attempts to use the force against him. Since these are council members, i'm thinking quite a few of them try it. so he loses possibly more than the listed, if the ones i didn't know well are powerful with the force.
Yeah but in the past (when the clone wars were still badass and not just CIS-losefests) he's taken on 3 council members at once and curbstomped them. Lets see though: He beats imo 3, 4, 5, 6, 7, 8, he should beat 9 but whatever, 10, 13, 14, 16, 17 and 18 and pose a challenge for all the others but Yoda and Mace.
In my opinion, this is the single most Badass thing to have come from Star Wars. All the Clone wars fights are like this (some of the Anakin vs Assajj Ventress ones are epic too).
I mean, at certain points he treats high-level Council members like fodder. That's Sidious-lvl man!
edit: I've just found out this isn't the original, I'll try to find the real one so we don't have to lsten to teh awful music of this one.
Yeah, watch that one, Much better than the last one. The fight with Dooku that you can see in related is also great, and Grievous looks like a ****ing monster in that cloak.
Think he would be a difficult opponent for 5 & 8 but they would defeat him.
He actually killed Adi Gallia. [SPOILER - highlight to read]: He will kill Eeth Koth in the CW cartoon. Coleman Trebor didn't really leave a good impression in EP2, so he would end up dead too.
well, it was to avoid making multiple grievous threads against each council member. This was faster, i probably should have called it something else though.
heres all of them IMO which ones grevious would win
1Yoda - LOSE DEFINITELY
2Mace Windu - Lose
3Ki-Adi-Mundi - Win but Ki- would put up a fight
4Plo Koon - lost because of plo's force
5Saesee Tiin - win
6Even Piell - win
7Oppo Rancisis - not shure
8Shaak Ti - win
9Kit Fisto - lose period. end of discussion.
10Agen Kolar - not shure
11Obi-Wan Kenobi - lose
12Anakin Skywalker - lose
13Adi Gallia - win
14Coleman Trebor - not shure
15Depa Bilaba - not shure
16Eeth Koth - lose
17Yaddle - win <--- debatable
18Yareal Proof - win? <---debatable
