General Grievous (Legends)

General Grievous, born as Qymaen jai Sheelal, is a secondary villain of the original Star Wars: Clone Wars series. He was voiced by John Dimaggio in the animated series.

Star Wars: Clone Wars
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 for the rest of his life, which would not be long.

Personality
The Legends Grievous was nothing like the.

The Legends General Grievous was a brilliant Separatist military strategist and a feared Jedi hunter, known for his ruthlessness and hacking cough. A twisted melding of flesh and metal, his body itself was a weapon, allowing him lightning quick strikes and devastating blows. He was also quick to retreat from a disadvantageous tactical position in battle, a tactic that worked until one final meeting with Obi-Wan Kenobi. He was also a brilliant military strategist who can't be bothered with compassion or mercy for his enemies. His lightning strikes and effective battle planning made him infamous in the eyes of the Republic, Grievous' living matter was encased within his precision-engineered artificial body; inside the hardened shell beat the heart of a remorseless Jedi killer. A pressurized gut-sack held his vital organs, while his skull-like mask contained his living eyes and brain. Each of his six-fingered arms could split in two, resulting in an array of four limbs, each armed with a lightsaber that he would take as a grim trophy of his foes. Grievous could spin these arms in a whirling storm of deadly light. Despite his imposing image, it seemed Grievous was a coward at heart, only entering into combat with opponents he believes he can defeat. This was due to invasive and manipulative brain surgery performed on him in secret by separatist scientists, and originally, Grievous was known to willingly take on seemingly impossible foes. His ruthlessness and thirst for victory at any cost made him Enemy Number One in the eyes of the Jedi Council.

Trivia

 * When Genndy Tartakovsky was creating 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.
 * After that a new was made but as a hero not a villain
 * General Grievous and Obi-Wan Kenobi are rivals in any Star Wars universe either hero or villain. The Clone Wars however, didn't have Grievous and Obi-Wan Kenobi fight however, except in one comic they met. however, has fought the villainous Obi-Wan various times.
