Obi-Wan is a master of Form III Combat style, which is considered to me nearly impossible to penetrate. Though not invincible.
Anakin also has exceptional fighting skills and is a master of Djem So, which is an aggressive combat style but being adept in aggressive combat styles does not always gives you edge in combat.
Anakin and Obi-Wan know each other very well so it will be a very close battle and if Anakin is thinking clearly then he has a slight chance of gaining victory. In Force contest, they are almost equals.
Maul is also a good fighter but Grievous is no push-over either. He can give Maul a very hard fight.
I say that there is 50/50 chance for both sides for scoring a victory. But this is not my final judgment.
Obi-Wan only wan because Anakin was so emotionally wrecked, he just Forced Choked the person he cared about the most and now he was fighting Obi, his brother(loved him like a brother), the 2 person he cared about the most.
Anakin and Obi-Wan know each other very well, but that doesn't mean, they know every single move the opponent will make, i think Anakin thinking clearly, would win against Obi. GG is better then Maul with blades, but Maul can Force crush his lungs or something like that.
Maul and Anakin win.
It all depends on whether or not it's EU Grievous or ROTS Grievous.
If it's EU Grievous then:
Anakin and Kenobi fight. Could go either way, depending on whetehr Anakin gets reckless or not. Eitehr way it lasts several minutes.
Grievous and Maul fight. Grievous wins after a pretty long fight, then goes and helps Kenobi. Together they destroy Anakin.
If it's ROTS Grievous then:
Anakin and Kenobi fight. Could go either way, depending on whetehr Anakin gets reckless or not. Eitehr way it lasts several minutes.
Grievous and Maul fight. Maul wins after a long fight fight, then goes and helps Anakin. Together they destroy Kenobi.
Yes, but even if its Eu GG, maul can use Force on him, he is a Sith, he has offensive powers, like what Mace Did to Eu GG and he is a Jedi, he hast got as many offensive powers as Maul.
The blood only protects him against mental powers, not physical ones such as TK. Seriously speaking, any jedi with somewhat competent TK ability should be able to defeat Grievous, there are simply so many ways it can be used against Grievous:
1. It can be used to affect the on/off button of his sabers. Grievous would be kinda screwed if midway through one of his attacks, his lightsaber unignited.
2. It can be used to destroy (crush) his sabers.
3. It can be used to pull his sabers away from him.
3. It can be used to slightly push him off balance, or trip him over.
4. It can be used to push Grievous back and up into the air (like what Obi did), and try to gain an advantage from his fall (run up and attack him before he can regain his composure fr instance).
5. It can be used to weaken or destroy his internal organs.
6. It can be used to hold him in the air with TK.
Really, far too many ways.
Majority of the Jedi cant use offensive powers like that, if they could those Jedi(kI Adi and the other) , Adi Galea, Pablo Jill and others would have used it in ther fights with GG, They don't know the powers, they never used them in their lives, they cant just mastered immediately and Force crush is prety extreme, i doubt any Jedi besides Mace would use it.
1. They were surprised.
2. They were tired.
3. They knew nothing about Grievous.
I have no doubt in my mind that if those three factors weren't plaguing the jedi, Ki-Adi-Mundi at least would have just been able to use the force to disable him, because while Ki isn't exactly the best swordsman, he's pretty strong with the force.
