I've had this Scenario simulated over and over in my head, especially after having returned to my Script for a Re-Imagined 'Attack of the Clones' and I must say that there still lies immense opportunity within the Choreographic descriptions of certain battles such as the Jango Fett vs Mace Windu duel.

Up until now, I have had this part written off as an explanation ; "Jango Fett survives Dooku's Betrayal and is incredibly injured leading to his ultimate defeat against Mace Windu who was conveniently there to battle him" and that of it's own can empower the reader's imagination however I'd like to take it a step further and present my own interpretation of a duel between the two with consideration of the power scaling difference between the two within This Universe.

Firstly, Jango Fett is a different bread within this universe, and the best description of him can be a War hardened warrior with a line of code and honor who had left his role of Governance to seek out what brings him Joy in the form of Combat, Risk, and Adventure. Having become ultimately the greatest Bounty Hunter and a Renowned Warrior always found in Conflicts across the galaxy. He possesses the most advanced Mandalorian Gear, Equipment, and Ultimately combat skills to the point he is Referred to as 'Fett of Mandalore' with the meaning of Fett within the Universe being Legend.

Secondly, He had already displayed a series of feats and capabilities in the movie, or previous shows/comics I had created as context behind his existence in the Universe. He is shown to be Capable of Capturing Obi Wan, of Defeating a number of Jedi, and being responsible for the creation of an Arial Acrobatic Maneuver allowing the user to Bypass force grips, as well as recoiling the Force Grip placed on them back to the Force User leaving his Arm Temporarily Numb as if he had slept on it an entire night.

Thirdly, Jango Fett is largely about match ups, like He'd ultimately be able to Defeat multiple powerful Jedi although is too likely to be overwhelmed by too many blaster fire, or too many opponents, or Strictly powerful Force Users. Hell his own son, later Boba Fett is more than likely to defeat him, that is if he was to keep his distance and remain vigilant throughout the battle.

Now, in the context of the Battle of Geonosis, Obi Wan had been captured, so has Anakin and Padme whom have been dispatched to retrieve Obi Wan before the Invasion Occurred. Jango Fett having been tasked by Dooku to reveal the Clone Army to the Jedi, and ultimately the Republic without leaving any leads tying to Dooku. Following this successful mission, he had been updated by Count Dooku to Eliminate the Jedi accompanying Obi Wan, and to retrieve him alive to then possibly be convinced to side with Dooku (In Opposition to Sidious by Dooku) Then there Dooku continues with Sidious's Plan by delivering an Ultimatum to the Republic forcing their hand to use the Convenient Clone Army against an Unsuspecting Separatist Droid Army. They do just that and attack the city. The Jedi and Clone Army arrive at the same time, with the Coruscant Guard given the Hardest Battle of the planet, that being the Capital City/Arena. There they tried to sabotage, Eliminate, and Rescue. Ultimately they were only able to Sabotage, and Rescue with Far less Jedi Casualties, around only 8 however nearly the Entirety of the Coruscant Guard with Exception to Commander fox having Died. Initially placed on Guard Duty and ensuring Dooku's Safety, following Coleman Trebor failed attempt to kill Dooku and being Brutally slimed by Jango, Dooku gave Fett an approval node allowing him to participate in the Blood shed. There he has the time of his life, by fighting Clones of himself, and Jedi, even grabbing the attention of the small Kashyyyk Expeditionary Force of Wookie Warriors that have begun to fire at him with Bow-Casters. Seeing this Jango Fett being there for the love of the game Decides to Increase his thrust to it's Maximum when charging head first into one of the blasts whilst in the Air. Leaving a Massive Shock Waves with even Impact Frames being shown. Then the next we see of him is just more chaotic fighting though Dooku's informed by Lord Sidious to Eliminate all loose ends and have Jango Fett killed. The Battle Droids all aim and fire at him with a number of explosives, including a Blast by a Armored Assault Tank hitting him, he was momentarily nocked back though was able to recover midair right before being hit by an LAAT completely damaging his Jet Pack and sending him crash landing into a Hanger Bay where Mace Windu had been. Jango Fett was incredibly injured, and lacked his iconic Jet Pack. He already had burnt his hand unnecessarily though remains protected by the bescar plating all over it. He had been injured in the Stomach and Shoulder as shown through the scorch marks. He suffered a number of blunt force trauma making him only capable of displaying a % of his capabilities. With this Mace Windu has a chance at succeeding.

Jango Fett proceeded to get up and as he's about to remove his Jet Pack, it then suddenly blows up and nocks him onto the ground. Sending Jango Fett's Helmate flying and further injuring him by leaving burn marks on the back of his neck and furthering the already existing pain from the Blunt Force Trauma already delt. Mace Windu turns to notice Jango Fett, having just secured the Hanger at the cost of the few clones who have acompanied him that can be observed dead on the ground as a communication device updates Mace Windu that Transports are headed towards his location. Mace Windu Quickly reacts to Jango Fett and Instinctually uses the force to push away Jango Fett's Helmet as he had thrusted to grab it in time.  Jango Fett leaping forward to grab his helmet was then force gripped as Mace Windu though this was Short Lived as Immediately Jango Fett initiates his Iconic Arial Maneuver by utilizing his remaining side thrusters (Feet, Back Foot, Lower Back, Ankles, Arms, and Shoulders) to escape the grip, and immediately does his deadly move of using the Marlinspiked Fibercord whip to try and skin off Mace Windu's Arm expecting the Force grip to recoil back, however Mace Windu had reacted quickly by using a small force push against the recoil, though the Fibercord latched onto his arm and tried to skin it off though was only able to rip away the armor he conveniently had on it. Mace Windu immediately yells out to him "Surrender Fett, or You will be Eliminated" though Fett being Fett he responds with, "You are Mistaken Master Jedi, and you will die for it" Mace Windu responds with "Then You Leave me no choice but to Defend myself" and ultimately the Battle Begins.

We don't see all of it as we cut away to other things however by the time we are back, we can see Mace Windu with a number of Bruises, to the point he's unable to properlly stand up without his right ankle acting weak and unbalanced. Likewise Jango Fett's Armor is Run Down with Saber Marks and the previous Blaster Scourch Marks all indicating his physically weakened state. Jango Fett is nitoriously known for Enjoying wounds, and the pain that comes with it, though it is evident to anyone that enjoying them or not they still effect a Fighter's combat capabilities negatively. Jango Fett can be seen using the famous Flame Thrower to parry Mace Windu and keep distances for whenever unable to parry with his Dark Saber, or to limit Mace Windu's manouverment by using his multiple small rockets which all can be located on his Right Shoulder, Left Arm, and both his knees. Mace Windu appears to be Physically exhausted all the whilst Jango Fett can be seen inject himself with Adrellilin and Stem Packs. Seizing the Opportunity Jango Fett thrusts in to then continue the duel through his Dark Saber by having Mace Windu's Saber be dragged by the Dark Saber's Magnetic Capabilities. Any Chance Jango Fett had to harm Mace Windu in any way is ceased, with it either being Impressive acrobatic spin kicks and flips to land physical blows such as bunches or uppercuts against Mace Windu for whenever Parried by Mace Windu's Far Superiori Dueling capabilities. Jango Fett is actively playing with fire though is more than capable of ensuring he is safe in consideration that his entire face is exposed meaning Mace Windu is genuinely able to Eliminate Jango Fett.   
  
Leaving Mace Windu defenseless and unable to parry he attempts to strike though is stopped by a force push nocking him away though is quickly recovered. The two attempt to strike and parry one another with Mace Windu successfully slashing Jango Fett once more on the shoulder though unable to penetrate the Bescar. Further More Jango Fett is able to utilize every opportunity to thrust kick or punch Mace Windu after every parry or block then Ultimately Mace Windu is able to use the force to throw a series of obsticales and lure Jango fett to another Saber Clash which has Jango Fett spin kick him away and quickly Fibercord grab Mace Windu's Lightsaber and immediately Jango Fett attempts to thrust towards Mace Windu however Mace Windu reacts quickly by using the force to send a series of obstacles slow him down though ultimately was injured in the shoulder by the Dark Saber just as he acquired his lightsaber through the force. Mace Windu then uses all his strength to launch Jango Fett in the opposite direction with all the surrounding obstacles resulting in an explosion by Jango Fett's Right Foot Thruster. This nocked him down and had Mace Windu force dash to quickly strike Jango who quickly reacts by parrying Mace Windu and tried to shoulder thrust, though Mace Windu expecting this used a Massive Force Push against Jango instead of going in for a strike which resulted in Jango being slammed to the ground and in an Attempt to Recover Jango Fett thrust backflip spins to try and land behind Mace Windu only for his attempt at a parry to fail with Mace Windu Ultimately cutting Jango Fett's head off just as his head was about to go over Mace's and evade him completely. Immediately collapsing to the ground following his Victory, he lies next to Jango Fett's body right behind him. Taking a second to get back up a Transport ship just arrives to retrieve him, as distant noises within the hanger complex can be heard. Mace Windu immediately reacts wanting to investigate though is called by the Clones to return to captured territory and receive medical oversight. Mace Windu Reluctantly agrees. Though to the audience we remain to witness Bossk arriving at the scene who has used Jango's Scent to locate him, and not too far behind him is a Young Boba. Entering the Hanger he sees Mace Windu escaping with the Transport in an incredibly wounded state though immediately rushes to the body and embraces it. Even shedding a tear all the whilst Boba is stun locked and unable to react at all to his Father's Death. Both Bossk and Boba are enraged by this and immediately grab the body, and Helmet.

Tell me if you wish to know other Scenes I have already created Coergography or the Blue Print Concepts behind them. I have a number of such scenes with Boba Fett, or other Iconic Star Wars Characters. 

This is how I'd have Jango Fett's life end in my 'Absolute Star Wars Re-Imagined' Project.
