I don't own Star Wars, but if I did, the storyline would have crashed and burned a long time ago. So, it's probably in everyone's best interests that I don't own it.
After countless hours of research, the Jedi council finally found out Grievous' weakness. Apparently, when he was being turned into a cyborg, San Hill removed his sense of honor, making him a ruthless killer. Now they knew that Grievous' mind could be altered, they could change him into a Jedi. They sent Jedi knights Anakin Skywalker and Obi-Wan Kenobi to reprogram him.
Ooo
As Obi-Wan sat in his quarters, he felt a dark surge in the force. It told him that Grievous had taken over Utopia. He would make a powerful ally, although first, he would have to be defeated.
They were landing now; he could sense battle droids coming up to the ship. Obi-Wan drew his lightsaber and opened the hatch. Then he and Anakin jumped out. The droids were scrap metal in seconds.
Then, he felt a surge in the Force and dived out of the way a second before a missile hit the spot where he had stood a second before. He looked up and saw a magnagaurd with a missile launcher. Suddenly, a lightsaber appeared in its head and it crumpled to the floor.
Anakin had thrown his light saber at it.
As they approached the building, two magnagaurds ran out wielding electro staffs. Defeating the magnagaurds took a little while longer than the battle droids, but they overpowered them in the end.
They ran towards the building. The Force told him to watch out in the entrance hall. He glanced at Anakin. He could tell that he sensed it too. Lightsaber drawn, he heard mechanical clacking. He dove out of the way just as Grievous jumped down from the ceiling.
He spun around to face Grievous, who had all four light sabers drawn. Anakin had not been so lucky, he had been knocked unconscious. Grievous turned to face Obi-Wan. "Jedi scum!" he yelled. Then he lunged at Obi-Wan, but his claws had gotten tied up in Anakin' robe. He fell down and his light sabers cut a pole and it hit him in the head. He fell and didn't get up.
"Looks like I'm doing the reprogramming," Obi-Wan muttered to himself. He hit Grievous twice with a wrench, and on the second try, a burst of sparks jumped out at him. "Hope that wasn't important, he muttered."
He then dragged Anakin and Grievous back to the ship, where he set the hyper drive for the Jedi temple. Then, he closed his eyes and went to sleep. A few hours later, he awoke to Grievous' mask six inches from his face
