Out of frustration when Padme arrived on the plant Mustafa, Anakin went to greet her and noticed she had brought Obi-Wan Kenobi. Anakin says "You brought him here to kill me". and so outraged he knew that Padme couldn't defend herself so took out his rage on her
Anakin Skywalker and Palpatine
Luke Skywalker would kill Anakin and bring balance to the force.
Anakin Skywalker, of course (He's the one who killed Count Dooku in Revenge of the Sith)
Count Dooku is killed in the beginning of Episode III by Anakin Skywalker cutting off his head.
Yes, she was killed by sand people.
He gets killed by Anakin on Mustafar in Episode III
Sort of. Anakin killed Padme by using the Force and choking her. He did this because, when he saw Obi-Wan with her in her shuttle, he thought she betrayed him by telling Obi-Wan they were married. Anakin let his anger get the better of him, causing him to loose the one thing he loved most... Padme. Actually, he didn't. He let go of her in time for her to survive. It was the fact that Anakin had become a Sith that killed, Padme died of a broken heart and sadness. And she died after the birth of her two twins, Leia and Luke Skywalker.
Count Dooku is defeated and killed by Anakin Skywalker
It is in fact Anakin Skywalker (Luke's father) who turns into Darth Vader. Anakin begins his turn to the darkside when he finds that his mother has been killed and he takes revenge on those who murdered her. Anakin's conversion to the darkside is completed when the emperor tells Anakin that he has killed the woman he loves (Padmé) and Anakin is consumed by guilt and anger.
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.
Well, she wasn't technically killed. She was taken prisoner by Tusken Raiders. But she has been held hostage for a month and when she died in Anakin's arms, she was battered, severely dehydrated and sleep-deprived. She was just too weak to hold on any longer
Count Dooku was killed by Anakin Skywalker during the Battle of Coruscant in "Star Wars: Episode III - Revenge of the Sith". Anakin decapitated him on Palpatine's orders, as part of his transformation into Darth Vader.
