Grievous looked hard at Kenobi. His cloak off, his sabers starting to whirl.
Kenobi looked hard likewise at Grievous, his saber activated, his hand forward in a battling stance.
The near pure mechanical Grievous began to spin, unlike what any organic being could have done, two of his lightsabers until they were a mere blur. Bringing his other two sabers behind, he slowly, his eyes intent on the prey, marched towards Kenobi.
Obi-Wan backed off, apprehensive of this unfeeling Kaleesh cyborg. But then he remembered. He used Soresu, and Grievous could try all he liked, but until there was an offensive weakness, Kenobi doubted the General could harm him. And when that weakness came, Obi-Wan's lightsaber would cut the Separatist general down with a quick flick of the wrist. Kenobi waited, until the General would strike.
Grievous was closer now. Surely the Jedi scum will back off now. His mind starting to back off itself from this seemingly terror starved display, Grievous brought his sabers from the ground and jumped, his four sabers flailing. Now that was a show that would surely scare Kenobi. Certainly, Kenobi moved back, but only for a second, bringing his saber down and cutting away one of Grievous' hands. The saber, a three fingered hand still clutching it, fell away cluttering to the floor.
The General landed, but badly, the early injury shocked him. He stared at Kenobi incredulous. Kenobi smiled, almost cheekily, the General should not have been flailing his arms like anything. Then again, the General still beat Kenobi by a saber count of 3 to 1.
Suddenly, Clonetroopers from every doorway rushed into the hanger, cocking their guns and shooting down every battle droid in sight. The General wheeled around as he looked upon the scene. He turned to Kenobi.
"Army or not, you must realise that you are doomed."
However, Grievous was not prepared to take the Clonetrooper onslaught, and ran towards the back of the hanger, jumping into his customised wheel bike. The bike activated, and before Obi-Wan realised what was happening, Grievous had shot through the hanger and was now jumping over the edge with the extra legs. In a split second, Obi-Wan jumped upon his trusty steed, Boga, and followed down after the general.
The chase was on, Kenobi slowly catching up with Grievous. Grievous looked around him, seeing and Obi-Wan, and cursed. This was going to be a more complex battle than he thought. Suddenly his eyes caught his blaster. That would do the job perfectly. Using two of his hands to keep at the wheel bike controls, he took his other hand, holding a blaster, and pointed it at the troublesome Jedi. Darting his head back and forth, he shot, as accurately as he could, at Obi-Wan.
Kenobi was a hard target, but the 15 metre long Boga was a different story. On his second shot, Grievous hit bang on on the feathered lizard's shoulder, Boga shrieked with pain, and stopped in her tracks.
Obi-Wan knew that it was the end of the chase for Boga, and so without any thought, he automatically jumped for the wheel bike, guiding himself slightly with the Force. He landed upon one of the main wheel holders of the chassis, inches away from Grievous.
The General started with a cry, and in doing so took another hand off the controls. He took advantage of this however, and with the now spare hand, clutched at Obi-Wan's throat. In the blaster hand, he pointed it straight at his head.
"Foolish Jedi!" Grievous shouted over the roar of the giant wheel careering down the sink hole. "You will now taste the bitter sensation of death, which I have come so close to in the past!" Over the roar, however, Grievous didn't hear the activation of a lightsaber.
Obi-Wan brought the saber up in an uppercut slash, decapitating the whole of the arm that had been choking him. If having Obi-Wan jump on his wheel bike didn't freak out Grievous, this did. Grievous took the shot, but his mind already knew it was too late. Obi-Wan had jumped onto the wall of the sink hole, and now with the aid of Force jumps, was clambering back up. The General waited a couple of seconds, judging his next move, before jumping off and stealthily following.
Obi-Wan quickly found Cody, and spoke equally so.
"Listen, Grievous will come back, I can sense it, but don't shoot him while we're duelling, it might have dangerous implications on me. Do you understand?"
"All clear, General." It made no difference anyway, Cody thought. He'll be dead soon.
General Grievous came up immediately, his fully operational arms grasping lightsabers. Obi-Wan sighed, back to square one.
Grievous ran forward, his arms spinning wildly, when he engaged Obi-Wan, their sabers screaming as they bashed away for a couple of minutes.
Kenobi's arms began slowly to tire from the attack, he jumped back, and then, before Grievous knew what was happening, he leaped onto one of the hanger's support beams. There he caught his breath.
The General looked up.
"Aha, the cowardly bird stands upon the tree where the canine cannot reach. Come down little bird, and I will cut your throat." The threats passed over the Jedi's head.
"And yet you were the one who desperately tried to escape from me on Utapau. A poor performance, my dear general. Are you losing your touch?"
Grievous growled.
"A tactical retreat, something that a mediocre strategist like you would not have heard of."
"In other words running up the tree."
The General's hot blooded mind could not take this banter any longer. Especially when it was calling him a coward. He bent down, and jumped, his mechanical legs able to mimic the Force aided feat that Kenobi had displayed.
He glared at Obi-Wan.
"I am thirsty, Jedi, I am parched. And it is not water that I crave."
With this hellish hint, Grievous leaped forward, his two sabers pointed forwards at the same point-Kenobi's head.
Obi-Wan decided to take a risky manoeuvre. He ran forwards towards the general as he was in the air. With a mechanical gasp, the Separatist General realised that Kenobi was behind him. He twisted, and landed facing the Jedi, a screech as his clawed feet stopped him against the durasteel beam.
"I am made of sturdier awareness than a droid, Jedi." Again he ran forward, swirling the sabers around and around, bewildering Obi-Wan. But Obi-Wan already had a plan. Grievous was easily distracted, all he had to do was focus on one blade, and-
He took his saber forward and hit one of the whirlpools of light emitting from Grievous. Grievous, with a cry, stopped, and looked down. Falling to the ground was a third hand. He turned back to Obi-Wan, only to find that the Republic General he sought wasn't there. But behind him.
Grievous had no time to lose. Bending low, his left foot swept around, only to find Obi-Wan jumping over it. Obi-Wan smiled cheekily.
"And my awareness is just as sturdy, my friend."
"I will not have scum like you call me friend."
With a snarl, Grievous lashed at Kenobi. An intense clashing followed, Obi-Wan being lead backward as he blocked Grievous' every attempt.
Finally, Kenobi found himself against a wall. A cold, dark wall. Grievous ceased. Holding his saber back in a position prepared to slash, he glanced at Obi-Wan's lightsaber. Turning back, he spoke, a hideous air of relish in his voice.
"Your lightsaber will make a wonderful price for my three hands, Jedi." He could have stopped there, but his glee at the victory swelled his burnt head. "The great Republic general Obi-Wan Kenobi. Your kind will speak of you for years to come. But they will speak of me more highly. I will see what I can do to have you honoured with a small statue on some faraway Outer Rim planet, for you have certainly been an honourable oppon-GAAAH!"
Kenobi Force-pushed Grievous back along the beam. Grievous lost his footing, and slipped down. In a split second, he dropped his final lightsaber and with the last free hand clung on tightly, the metal fingers carving into the beam. Kenobi was not in a hurry to give him a chance. Throwing his saber, he directed it towards the clinging arm. It sliced through the elbow, sending a cursing Grievous down to the floor. The lightsaber span round the hanger, and found itself in the trusty hands of Kenobi once more.
The general, meanwhile got up, his breathing weakened, the inhales and exhales echoing around. He looked up to Kenobi. Panting in between each word, he spoke.
"You…will…surely…die…Jedi. I will…not…forget…this…infringe-infrin…this…attack…on my…honour."
Turning away, he staggered away from the hanger.
Kenobi suddenly realised the situation he was in. He was letting the Separatist general go. And why weren't the clonetroopers pursuing?
Running along the beam, he jumped down. It was then that something told him not to. A disturbance. Their battle had come to a stalemate, and he sensed that that would be their only time they came lightsaber-to-lightsaber. But it would also be the General's last stalemate.
"I'm sorry sir."
Commander Cody's voice. Obi-Wan turned around.
"Sorry for what, Commander?"
Then he saw Commander Cody, a gun in his hand, pointing at Kenobi. And the dozens of clonetroopers surrounding him. Guns in their hands. Pointed at Kenobi. Obi-Wan raised his eyebrows.
"Oh."
