The beginning of the end.
Bravo my man! I like...I like...
Ok here goes,
round 1 - sabers: I believe Dooku and Anakin take it after a LONG fought battle. Anakin can take just about anyone in saber combat, so he'd go after Sidious, and Dooku would take on Maul. I see Maul hurting Dooku a little, but Dooku pulling out a hard fought win, same as Anakin only with no injuries going to Anakin.
Round 2 - force: This gets tricky. Sidious is the best here obviously, and I believe Maul to be the weakest. Dooku is also very gifted in the force and i believe close to Sidious. Sidious has the lighting on lock, but if Dooku can produce it, I'd be willing to bet that he can deflect it, much like he did with Yoda. Anakin and Maul are susceptible to lightning, and although Maul withstood lightning from that Witch, I'm sure that's nowhere near comparable to Dooku's. While Anakin is strong in the force, he doesn't seem to have the needed control over it to win a force contest with Sidious. Likewise with Maul to Dooku. However, I say Sidious and Maul take this due mostly in part to Sidious.
round 3 - all out: I say Anakin and Dooku. If Anakin/Vader reaches his "zone," I don't think anyone here would be able to stop him. He wouldn't reach his retard rage state since Padme and OB1 aren't a part of the equation, so he'd be virtually unstoppable. Considering how he ran through Dooku like nothing, I think he could do the same to Maul, however with slightly more difficulty due to Maul's ferocity. If that's how it played out, I think Vader could take out Maul before Sidious could take out Dooku, then Vader runs over to help destroy Sidious. On the flip side, I think Dooku could beat Maul quickly with the force, or severely weaken him with it then finish it with sabers; and Vader could defeat Sidious.
Thats my story and I'm stickin' to it!
