That depends at what time you are referring to. Prior to Anakin's mutilation at Mustafar, he would probably have been able to defeat Sidious, since his potential to use the force was higher than any being of the age. However, after Anakin was fixed with cybernetics, his ability to use the force was greatly hindered, so at this time, he probably would not have been able to defeat Sidious.
Anakin because the only reason why sidious wanted him to be his apprentice is because he was more stronger and more powerful than any Jedi or sith.Even stronger than sidious himself!.
Anakin Skywalker and Palpatine
look at Revenge of the Sith Chancellor Palpatine was talking about Darth plaguies when he said life he looks directly at Anakin's face and you almost expect him to say "you" so Darth Sidious saw his master Darth Plaguies creating Anakin Skywalker. Darth Sidious saw that Anakin will replace him as Darth Plaguies' apprentice so Darth Sidious killed him in his nap.
He didnt change it. Darth Sidious did when Anakin became a Sith. It is traditional for the Sith to bear the name "Darth."
Palpatine
Darth
Anakin Skywalker would win since he has a lightsaber and the force and wonder women has bullet proof bracelets and a lasso.
anakin skywalker Anakin is a whiny bitch, Chief wins hands down. anakin is a jedi case closed
sonic
No one. Vader would have to battle himself since Anakin turned into Darth Vader in Episode 3.
wonder woman, tough.
It is not Anakin Solo. It is Anakin Skywalker and he is not dead. He became Darth Vader. EDIT: Anakin Solo was the son of Han Solo and Leia Organa, and was killed being overwhelmed by the Vong. The event started a cascade through the family, his sister came close to the dark side and Jaycen solidified his dark side role through this event also.
