>Episode 3: ORDER 66
Palpatine has now complete control of the senate, with his personal bodyguard and right hand man: Lord Vader.
Palpatine convinces the public that the Jedi are evil, and hunts them down.
Anakin travels around the galaxy with legions of stormtroopers hunting down Jedi & rebels. It becomes clear how strong Anakin really is. He mows most of them down with ease. We actually see him training new skills under Palpatine, become stronger over time.
The jedi are being decimated, and Obi-Wan assembles the last remaining members of the council on a planet in the outer rim: Mustafar.
From there, they lay low while they come up with a plan to defeat the emperor.
Unfortunately, their location is found.
Anakin, now at full sith lord strength, takes on the council:
He slices through Mace Windu like he's nothing.
Yoda gets a few hits in, but is also badly wounded. Barely manages to get away with his life.
In the end only one Jedi is left standing: Obi-Wan.(He was late to arrive, because he spent the last few months helping a pregnant Padmé on the run)
Who realises he has failed his former padawan. He loves Anakin, but knows there is no hope for him.
The epic fight begins, It looks like an impossible task for Obi-Wan, but by sheer willpower he seems to be able to match Anakin's strength.
In the end, Anakin makes a wrong move, Obi-Wan cuts off his limbs and runs off.
Palpatine senses Anakin is in trouble, Puts him in the Vader-suit. His powers are severely weakened in this suit. He becomes bitter and depressed. His ego has completely crumbled. All that's left is his hatred.
