Rank: Supreme Commander of the Separatist Droid Army but prefers to still to go by General
Spiecies: Former Kaleesh but now a cybernetic warrior to destroy the Jedi and the Republic
A Long time ago in a Galaxy far, far away
A Kaleesh Warlord and feared warrior from the Planet Kalee, Grievous learned battle tactics and warfare during Kalee's war against the Yam'rii of Huk. Grievous also developed a personal vendetta against the Galactic Republic during this conflict because of the government's support to the Yam'rii. At some point in his life, Grievous became a cyborg following a serious accident that destroyed most of his body and almost killed him, but afterwards he chose to receive extreme cybernetic upgrades to increase his skills in combat and to become even more threatening While the transformation left Grievous to be more cybernetic than living Kaleesh flesh, Grievous saw his cyborg implants as improvements.
While Grievous claimed his old form was no more than weak flesh, Grievous had several reminders of his past life. As a cyborg, Grievous wore a Kaleesh cloak, which was a vestige of his past identity, and the type of fearsome mask that was often worn by Kaleesh warriors. By the time he owned his fortress on Vassek, Grievous had several statues that showed a progression from his organic life to that of a cyborg. After Grievous's reconstruction, all that remained of his original body were his brain, eyes, several vital organs,spinal cord, and a small amount of red Kaleesh flesh could still be seen around his eyes. Grievous's armor and synthskin gut-sack protected his remaining vital organs, but his organic lungs were irritated by their implants. This gave Grievous a persistent cough for the rest of his life.
After Grievous received his cybernetic enhancements and trained in lightsaber combat by Count Dooku, he gained the rank of General in the Confederacy military. Serving as the Supreme Commander of the Droid Army,his forces engaged the Grand Army of the Republic in the Clone Wars, and, under his command, the Separatist Droid Army moved throughout the galaxy. Early into the war, around the time of the Battle of Christophsis, Grievous had already spread Republic forces thin. While the war against the Yam'rii had given Grievous a vendetta against the Republic, Grievous had changed by the Clone Wars. Grievous now was indifferent to the Republic, and his main goal was to see the extermination of the Jedi Order. Grievous fought against numerous Jedi during the war, and he and defeated and killed many. Grievous was proved him to be a feared Jedi Hunter. The General collected lightsabers and other trophies from the Jedi he killed and kept them in his growing collection.
As the Separatist Army's leader, Grievous caused fear throughout the Republic, and as a number of galactic citizens saw Dooku as noble yet misguided, many saw Grievous as the true face of the Confederacy. Jedi Anakin Skywalker considered him a monster that needed to be stopped, but Skywalker and Grievous would not meet face-to-face until the war had nearly reached its conclusion. However, Grievous did encounter the Jedi Master Obi-Wan Kenobi, and the two fought each other numerous times throughout the war.
Ultimately, the Republic held all the momentum for the third year of the war. The Separatists were pushed to the Outer Rim Territories, and, in the campaign known as the Out Rim Sieges, the forces of the Republic kept up the pressure. A surrender from the Separatists seemed as though it would come in due time, but, with the Republic Military occupied in the galaxy's spiral arms, the capital of Coruscant was left with fewer defenses. Republic strategists were not worried, but Sidious arranged for Grievous to launch a massive assault to capture Sidous's alter ego, Supreme Chancellor Sheev Palpatine. The Coruscant Home Defense Fleet was caught off guard, and, with the chaos and Confederacy Navy providing cover, Grievous and a strike team could land on Coruscant's surface. Grievous landed in the Exective District and fought his way through layers of security forces and Jedi to secure Palpatine, killing Jedi Roron Corobb and knocking out Master Shaak Ti with electrified cables and stealing her lightsaber in the process.
Grievous then took the Chancellor aboard his flagship the Invisible Hand. Jedi Knights Anakin Skywalker and Obi-Wan Kenobi boarded the Invisible Hand to rescue the Chancellor. They first defeated Count Dooku and were escaping with the Chancellor when Grievous captured them, meeting with Skywalker face to face for the first time. The Jedi broke free of their bonds, and after destroying IG-101 and IG-102, the pair cornered Grievous. Too wounded to fight, the General had to shatter the front window of the cruiser with an electrostaff. Kenobi, Skywalker and the Chancellor managed to stay in the ship, but Grievous was sucked into space. Protected from exposure to vacuum, the general survived and used a grappling hook installed in his arm to latch onto the hull of the ship.
After ejecting the rest to trap the Jedi and the Chancellor inside, Grievous fled in one of his dying flagship's escape pods, and later headed for the secured planet of Utapau in the Outer Rim Territories, where the Separatist Council was hiding. With Count Dooku's death, Grievous succeeded him as Head of State of the Confederacy of Independent Systems. Under the direct order of Dooku's Master, Darth Sidious, Grievous was to relocate the Council to the planet Mustafar.
After the Republic received word that Grievous was hiding on Utapau, General Kenobi was sent to defeat him. Kenobi watched as Grievous spoke to the Separatist Council, and though Nute Gunray doubted Grievous's ability to keep them safe, they followed his orders and left just moments before Kenobi would jump down to Grievous.
Kenobi jumped down from a bar above and greeted Grievous, who applauded his audacity before ordering his bodyguards to kill the Jedi Master. After Kenobi handily defeated Grievous' bodyguards, the droid army prepared to open fire. However, Grievous ordered them to back away as he decided to engage Kenobi himself. He immediately split his arms in four and attacked the Jedi Master in one last duel. But the injuries to his left side had not yet been treated and, as a consequence to either his negligence or a lack of spare parts, he was apparently unable to fight as well as he used to. Grievous lost two of his hands to Kenobi before Clone Commander "Cody" and the 212th Attack Battalion arrived, ambushing the droid army. Fighting broke out all over Pau City between droid and clone forces. Grievous continued to threaten Kenobi, but Kenobi ended the initial duel with a tremendous Force push that disarmed the general. Grievous fled on his wheel bike.
Pursued by Kenobi on a varactyl named Boga, after a prolonged chase and running duel, the two soon crashed onto Grievous' private landing platform, where the Soulless One was docked. As they fought hand-to-hand, Grievous made use of his mechanical body's superior strength. However, Kenobi managed to rip open Grievous' chest plates, revealing Grievous' gut-sack. Angered, Grievous tossed Kenobi off the platform, but the Jedi manipulated his position via Force and caught hold of the edge. Grievous charged Kenobi with an electrostaff, preparing to finish off his old adversary. However, Kenobi used the Force to summon Grievous' blaster, shooting Grievous five times in his exposed gut-sack. The oils preserving Grievous' remaining biological components ignited, incinerating the famed cyborg from the inside and finally destroying him.
After his death The Empire rose into power, strong and killed most of the Jedi. They took General Grivous's body and researched it they could replace their emperors right hand only for it to blow in their faces. So The Emperor locked away the remains of Grievous so that it could be used again by scientists for the project known as NK. But their project was cut short when one of the scientists stole Grievous and took him in order to make Grievous home planet he was still alive and make an army to take over the Galaxy. But in the end Grievous's body was broken apart by bounty hunters who would sell his parts.
Everything that happened led to one Grand Admiral taking the mask of Grievous in a collection of ancient artifacts and war trinkets. But something stirred, a dark aura could be seen in the eye sockets as if life was still in them. Years had past and the Empire was no more; What remained of the Empire took the mask of Grievous and decided one more project must be done if the Empire were to survive. They put Grievous back together, but with more stronger parts, a better yet slicker armor that would be resistant to blunt objects like pure steel hammers and hard metal that lightsabers could not penetrate his armored body. They took him to a asteroid field filled with the Darkside of the force. They shot him into space with the intent of collecting enough energy from the darkside to make an army of Sith warriors.
But when Grievous absorbed most of the darkside, something stirred inside of him. All the memories from the past, the battles, the rage...it all came back to him. Soon enough he started to feel agony for the first time as the one thing that was keeping the former dead General from feeling anything was the inhibitar of that in his brain. A great push led to him flying toward the ship of scientists breaking through the hanger bay slaughtering those inside. Now conufused and floating in the echos of space all he could do was contemplate his next move; that was simple...revenge on this new galaxy, and repair the Droid Army...one way or another.
The first he did was enter Coruscant where he slipped into the the lines of the fallen Empire and straight to the Emperor's chambers. He stole the two lightsabers that belonged to Darth Sidious, then went to his statue only to tear it down revealing yet another; three light sabers were now part of his collection, and a fourth was closer then he thought As he went to one of Sidius's treasure rooms finding Count Dooku's, Darth Plagus and Darth Bane's lightsabers intact. He would question how he got them but decided against it as he would make his leave killing a few guards on the way while taking the droids that were in the treasure room as his own. Now the only thing he needed was transportation with a hyperdrive. With his magna droid Grievous managed to cut down what remained of the stormtroopers that were guarding the shipyard. Taking a private ship they left the planet only to head straight to Mustafar.
There he learned that things were more complicated as things were. The planet was more of a castle domain and reeked of death, and not to mention the late Sith Lord. His data banks recollected about Darth Vader, he knew who he was and what he has became. But at the time that didn't matter to Grievous, all that mattered was preparing for the new age. He restarted production of the battle droids and hired engineers to make shipd to carry all the droids and including the making of a few Lucrehulks to operate them. When the First Order and the Resistance began to fight General Grievous had already had his own dreadnoutght; he calls it the Harbinger, with it he uses the ship to hyper speed to any planet he desired.
