General Grievous

General Grievous is a fictional character and recurring antagonist of the Star Wars franchise.

He served as the tertiary antagonist in Star Wars Episode III: Revenge of the Sith, a major antagonist in the 2003 micro-series Star Wars: Clone Wars, and one of the secondary antagonists in the 2009 - 2013 TV series Star Wars: The Clone Wars.

History
In Star Wars: Clone Wars, General Grievous's first public appearance is when he attacked several Jedi on Hypori. After killing Daakman Barrek, Grievous surrounded Tarr Seirr, Sha'a Gi, Aayla Secura, K'Kruhk, Ki-Adi-Mundi and Shaak Ti. After stating he would grant the Jedi a "warrior's death", Grievous killed Gi, and Seirr then injured Secura, Ti, and K'kruhk. He managed to possess three lightsabers (one in each hand and the third using his left foot) to fight Mundi. As they fought lightsabers blazing, clone troopers arrived to save the surviving Jedi from Grievous, though they left K'kruhk thinking he was dead.

Sometime later, Grievous searched for Supreme Chancellor Palpatine on Coruscant and fought several Jedi that took Palpatine to a secret bunker aboard a maglev train. However, Grievous and his MagnaGuards reached the hardened bunker and made his way to Palpatine. As Grievous was about to escape, Mace Windu Force-crushed his chest plates which severely damaged his lungs which gave him terrible coughing and wheezing problems.

Star Wars: Episode III - Revenge of The Sith
In Star Wars Episode III: Revenge of the Sith, General Grievous holds Supreme Chancellor Palpatine hostage aboard his flagship Invisible Hand. After a rescue operation results in Count Dooku's death at Anakin Skywalker's hands, Grievous retreats from the battle after the Jedi infiltrate his command bridge and later takes command over the Separatist Council.

Now the Republic's top priority, Grievous takes refuge on the sinkhole planet Utapau, the Separatist Council's base. Under orders from Darth Sidious, Grievous relocates the Council to the volcanic planet Mustafar. After Palpatine authorizies an invasion of Utapau, Grievous engages Obi-Wan Kenobi in a lightsaber duel. When Kenobi gains an early advantage, Grievous flees the scene towards his starfighter with Kenobi hot on his heels. The chase ends at Grievous's secret hangar where the pair fight hand to hand. Making use of his robotic body, the general has the clear advantage in the brawl and prepares to kill Kenobi but the Jedi Master manages to rip open his chestplate in the process. Using the Force to pull Grievous's blaster to him, Kenobi fires five shots into the cyborg's heart, incinerating him from the inside.

Trivia

 * In both the popular T.V. show and the 3rd film in the Star Wars saga, General Grievous seems to have an alliance with Count Dooku.
 * When Genndy Tartakovsky was creating The Clone Wars, George Lucas explained that General Grievous was the main villain of Revenge of the Sith which led Genndy to creating General Grievous in the series. In the series, Grievous was cold-machine that hunted Jedi by taking their lightsabers and later the Jedi were after him always in The Clone Wars series. His chest was force-crushed in the Clone Wars. After this, Lucas needed a new design for Grievous in the Movie which led to the creation of General Grievous for his villainous appearance of coughing and wheezing in the Movie.
