Meanwhile back on Utapau Obi-wan continued to follow Grievous through many hot zones, with clones and droids alike going down. As the chase went on Grievous grabbed a Magnastaff from a compartment on his bike and activated it. When Obi-wan was right next to him Grievous tried to shock him with the staff but Obi-wan grabbed onto it. They struggled until they were forced to depart due to the distance leaving Obi-wan with the staff. Obi-wan then struck the wheel of Grievous' bike before striking Grievous across the faceplate. Grievous retaliated by grabbing the staff and yanking it towards him bringing Obi-wan with it. Grievous and Obi-wan then struggled over the staff before Grievous grabbed a blaster intending to kill Obi-wan. But Obi-wan dodged out of the way and the two tumbled out of the bike as it fell never to be seen again. Obi-wan grabbed the staff as Grievous grabbed the blaster causing Obi-wan to knock it out of his hand. Obi-wan then struck Grievous' stomach and went for a right head strike which Grievous blocked before Obi-wan knocked him down. Obi-wan then stabbed Grievous in the stomach causing electricity to spark before Grievous kicked him backwards. Grievous the stalked towards Obi-wan and slammed him into Grievous' ship. Grievous then grabbed Obi-wan by the throat and went to punch him but the old Jedi dodged giving himself time to pry open Grievous' organ carrier. Grievous growled smacking Obi-wan back and tried stepping on him which the he dodged and landed a kick on Grievous' leg not knowing it was metal and grunted in pain. Grievous then through Obi-wan forward causing him to fall off the ledge which Grievous then grabbed the staff and stalked over to the hanging Jedi. As Grievous got closer Obi-wan noticed the blaster and used the Force to call it to him and shot Grievous straight in the organ carrier which caused it to burn. Grievous bent over and started growling causing Obi-wan to fire again and again until fire spewed from his eyes and his faceplate exploded. As Grievous lay dead Obi-wan hoisted himself up and walked over to Grievous' body. "So uncivilized" he groaned tossing the blaster away as he examined Grievous' body which smoked slightly.
Meanwhile on Coruscant Anakin went to find Mace Windu and tell him of his discovery. "Master Windu I must talk with you" Anakin told him. "Skywalker we just received word that Obi-wan has destroyed General Grievous and we're on our way to make sure the Chancellor returns emergency powers back to the Senate" Windu informed as the two walked. "He won't give up his power I have just learned a terrible truth, I think Chancellor Palpatine is a Sith Lord" Anakin told him causing him to stop and look at Anakin in shock. "A Sith Lord?" he gasped which Anakin nodded "yes the one we've been looking for" Anakin assured. "How do you know this?" Windu questioned. "He knows the ways of the Force, he's been trained to use the dark side" Anakin explained. "Are you sure?" Windu asked "absolutely" Anakin swore. "Then our worst fears have been realized we must move quickly if the Jedi Order is to survive" Windu explained. "Master the Chancellor is very powerful you'll need my help if you are going to arrest him" Anakin told him. "For your own good stay out of this affair I sense a great deal of confusion in you young Skywalker there is much fear that cloud your judgement" Windu denied. "I must go Master" Anakin insisted. "No if what you've told me is true then you have gained my trust but for now remain here, wait in the council chambers until we return" Windu ordered. "Yes Master" Anakin relented as Windu headed to the transport.
Meanwhile Melaena sat on the couch in her apartment waiting for Anakin before she walked up to her window and looked at the Jedi Temple in the distance.
In the Jedi council room Anakin sat in his chair deep in thought before he too walked to the window. "You do know don't you? If the Jedi destroy me any chance of saving her will be lost" Palpatine's voice spoke in Anakin's head. Anakin took a deep breath and suddenly turned around and headed for the docking bay with his decision made and hopped in a ship before flying towards the Chancellor's office
Meanwhile Mace, Kit Fisto, and two other Jedi walked inside Palpatine's office. Hearing footsteps behind him Palpatine turned around in his chair to greet them "Master Windu I take General Grievous has been destroyed?" the Jedi offered no reply "I must say you are here sooner than expected" Palpatine said wearily. "In the name of the Galactic Senate of the Republic you are under arrest Chancellor" Mace stated as he and the others activated their lightsabers. "Are you threatening me Master Jedi?" Palpatine growled. "The Senate will decide your fate" Mace told him. "I am the Senate" Palpatine snarled. "Not yet" Mace warned. Palpatine stood up and pulled out a lightsaber from his sleeve "it's treason then" he said before letting out a war cry striking down two of the Jedi before moving on to Mace and Kit. The ferocity of Palpatine's attacks soon became too much for Kit as he too was struck down leaving Mace to fight him off. As the moved through the room striking multiple blows Mace then blocked an attack getting right in Palpatine's face who was struggling to hold.
Meanwhile Anakin's ship landed in one of the hangar bays before he jumped out and sprinted towards Palpatine's office.
Back in the office Mace and Palpatine continued their duel striking blow after blow which Palpatine flipped over before resuming his attack. The two moved closer to the window which shattered when they both struck it. Palpatine gets desperate sending stab blows which Mace countered before kicking the lightsaber out of his hand causing Palpatine to stumble and scramble away against the wall. Anakin finally reached the office to see Mace pointing his lightsaber at Palpatine. "You are under arrest my lord" Mace sneered before taking notice of Anakin and halted him. "Anakin I told you it would come to this, I was right the Jedi are taking over!" Palpatine exclaimed. "The oppression of the Sith will never return, you have lost" Mace stated to Palpatine. "No, no no no you will die!" Palpatine snarled sending a wave of Sith Lightning which Mace blocked with his lightsaber. "He's a traitor!" Palpatine exclaimed. "He is the traitor" Mace denied straining as the lightning started hitting Palpatine. "I have the power to save the one you love! you must choose!" Palpatine said desperately. "Don't listen to him Anakin" Mace told him as the lightning started deforming Palpatine. "Don't let him kill me!" Palpatine begged. The lightning continued to hit Palpatine causing him to grow weak "I can't hold it any longer, I-I-I-I can't, I-I-I'm weak, I'm too weak" he rasped out before the lightning finally stopped. "Anakin! Help me! Help me" he begged "I-I-I can't hold on any longer" Palpatine rasped as Mace pointed his lightsaber again at the Sith Lord. "I'm going to end this once and for all" Mace said which Anakin interrupted "you can't, he must stand trial" he told Mace. "He has control of the Senate and the courts he's too dangerous to be left alive" Mace hold him trying to get him to see reason. Palpatine moaned in pain "oh I'm too weak, don't kill me please" he begged. "It's not the Jedi way, he must live" Anakin said desperately but Mace wouldn't give in. Noticing the look Palpatine's eyes widened "please don't" he begged. "I need him" Anakin said as Mace lifted up his blade for the killing blow. "Please don't!" Palpatine exclaimed before Anakin activated his lightsaber "No!" he screamed as he slashed off Mace's hand causing him to gasp and scream in pain. Smiling briefly at Anakin's choice Palpatine then sent a wave of lightning at the now unarmed Mace Windu "Power! Unlimited power!" Palpatine exclaimed in sadistic glee before tossing Mace out the window before sighing in relief while Anakin looked up in horror at what he'd just done "what have I done" he whispered in horror. Standing up and turning towards Anakin Palpatine looked at him with pride "you're fulfilling your destiny Anakin, become my apprentice and learn to use the dark side of the Force" he told Anakin. "I will do whatever you ask" Anakin gasped out still in shock. Palpatine smiled evilly "good" he said in glee. "Just help me save Melaena's life, I can't live without her" Anakin begged. "To cheat death is power only one has achieved but if we work together I know we will discover the secret" Palpatine assured. Anakin then bowed to his knee "I pledge myself to your teachings" he swore. "good, good" Palpatine said pleased before basking in Anakin's connection to the Force "the Force is strong with you, a powerful Sith you will become, hence forth you shall be known as Darth Vader" he bestowed onto Anakin. "Thank you my master" Anakin said bowing his head. "Rise" Palpatine ordered as he walked over to his desk and pulled on a robe. "Because the council did not trust you my young apprentice I believe you are the only Jedi with no knowledge of this plot, once the Jedi learn what has transpired here they will kill us along with all the Senators" Palpatine stated putting on his hood. "I agree the council's next move will be against the Senate" Anakin agreed. "Every single Jedi including your friends Obi-wan Kenobi and Jason Pandora is now an enemy of the Republic" Palpatine told him. "I understand Master" Anakin assured. "We must move quickly the Jedi are relentless if they are not all destroyed it would be civil war without end, first I want you to go to the Jedi Temple and catch them off-balance, do what must be done Lord Vader, do not hesitate, show no mercy" Palpatine ordered. "Only then will you be strong enough with the dark side to save Melaena" Palpatine assured as Anakin walked in front of him. "What about the other Jedi spread across the galaxy?" Anakin asked. "Their betrayal will be dealt with" Palpatine told him as he sat down in his chair "after you have killed all the Jedi in the Temple go to the Mustafar system, wipe out Viceroy Gunray and the other Separatist leaders so once more the Sith will rule the galaxy, and we shall have peace" Palpatine assured with a smile.
Later battalions of clone troops stormed the Temple with the newly dubbed Darth Vader standing in front leading them determined to carry out his new Master's will.
Meanwhile on Utapau clone troops are seen battling the remaining droids as Obi-wan sped past them on his mount. Then he finally reached Commander Cody who removed his helmet to greet him. "Commander contact your troops tell them to move to the higher levels" Obi-wan ordered over the blaster fire. Cody nodded "very good sir oh and by the way I think you will be needing this" he said handing Obi-wan his lightsaber causing the old master to smile. "Thank you Cody now lets get a move on we have a battle to win here ha!" Obi-wan ordered before speeding off. When Obi-wan started heading upwards Cody put his helmet back on and activated his beeping comlink to reveal Sidious. "Commander Cody, the time has come execute Order 66" Sidous ordered. "Yes my lord" Cody replied before turning to the other clones manning a tank. "Blast him!" he ordered which the tank shot at Obi-wan who tumbled down in towards the water below his mount whining sadly.
Meanwhile on Mygeeto Master Ki Adi Mundi fought with his clone soldiers before calling out "come on!" he said running forward which the clones followed but stopped abruptly. Noticing the clones stopping he turned around only to see them have their blasters aimed at him and looked in shock before they fired. He blocked some of them but soon became overwhelmed and was shot dead.
On Felucia Aayla and Jason stood looking at the view before their clones aimed their weapons at them. Jason quickly blocked the bolts and used Repulse on them killing them. When he looked over at Aayla he could only see her riddled with many blaster bolts. Jason quickly cradled her sobbing softly shaking his head before screaming to the sky at the loss of his friend.
On Kashyyk Yoda suddenly dropped his cane and held his head feeling all the Jedi being slain.
Master Plo Koon flew in his starfighter with clone pilots before one of them received the transmission from Sidious "Execute Order 66" he told the pilot. "It will be done my lord" the pilot said before they fired upon a surprised Plo Koon before his ship crashed into a pillar reducing him and his ship to ash.
With Adi Gallia she and two clone troops sped off before one of the troops also received the order and haulted back and fired upon Adi Gallia causing her to crash and die upon impact while the troops sped past.
Back on Kashyyk the battle continued to rage on as the Wookiees destroyed the droids. On one of the balconies a clone is seen replying to the order Sidious gave "it will be done my lord" he said before joining one of the scout troops behind Yoda and they aimed their weapons at him. However before they could fire Yoda activated his lightsaber slicing off both of their heads causing their bodies to tumble down. The commotion startled Chewbacca and Tarrful before Tarrful picked up Yoda and ran off.
Back at the Temple the clones killed Jedi after Jedi, Masters and Padawans alike. While they did Anakin walked inside the council chambers revealing the younglings hiding behind the chairs. "Master Skywalker there are too many of them what are we going to do?" one of the boys asked. Anakin just looked at them in pure hatred before activating his lightsaber.
In Melaena's apartment she stood in front of the window and watched as the Temple burned before 3PO walked up to her. "The Chancellor's office indicated that Master Anakin returned to the Jedi Temple, don't worry I'm sure he'll be alright" 3PO assured before walking away. When he was out of sight Melaena sobbed quietly worrying about her husband.
