Darth Sidious (Dynamic Force Crisis)

"Good... Good... Use your aggressive feelings, my apprentice... Let the hate flow through you... May you strike your father down as he hungers to strike me..."

- Darth Sidious, to Luke Skywalker

Darth Sidious, a Force-sensitive Human male, was one of the last surviving members of the Order of the Sith Lords during the Great Era of the Galactic Republic, and eventually became one of the most powerful and notorious s ever known to.

Born to the , the young Sheev Palpatine was strong in the , but his potential had escaped the notice of the Jedi Order of his existence, and his future ,  (the same mysterious individual who kept Palapatine's presence from the Jedi Order), recruited and trained the young Nabooian into the secret Sith organization that was the Order of the Sith Lords, as his , whom he eventually dubbed as  Sidious. Sidious would later become a on his home planet, which was the beginning of his master's  for instating the  to rule upon the galaxy. Palpatine lived a double life for many years, serving an untarnished career as Naboo's ambassador in the Galactic Senate while learning from his master and training a young Zabrak as the Sith assassin Darth Maul.

Sidious would eventually be elected of the Galactic Republic, and, shortly afterwards, would murder Plagueis in his sleep, and seize the mantle of  for himself. In 18 BBY, Palpatine revealed his identity as Darth Sidious to the Jedi Knight Anakin Skywalker, telling that the dark side teachings that Plagueis had pursued could help Skywalker to save his wife, whom Skywalker had foreseen dying untimely. Despite his efforts to seduce the Chosen One into the of The Force, however, Skywalker would end up becoming uplifted by the, completely turning against Sidious after witnessing his old friend and Jedi Master Obi-Wan Kenobi died at the hands of Palpatine later on. In the years that followed, Sidious attempted to establish an, with himself as its , and, thus, continued his variation of the Grand Plan, which involved starting the Clone Wars, a galaxy-wide conflict that resulted in the deaths of billions of sentient lives, and secretly controlling both sides, until his plan was discovered by the , forcing him to separate himself from the Core Worlds for a while and dwell across both the rest of the known regions of space and one-third of the the Unknown Regions, wherein he would find more ruthless allies supporting his campaign, both for the future of the Sith and the galaxy itself. As the now-infamous Emperor Sidious, the ruler of both the Galactic Empire and the Sith, he began training a new generation of Sith apprentices which included Darth Tyranus,, , , and many others who would later ensure the survival of the Sith in the new form of a brotherhood, a few years after his and his empire's eventual fall.

As the Galactic Republic have fully fallen into the diabolical form of the Galactic Empire, the remaining Jedi Order across the galaxy have gathered and subsequently exposed most of the into revealing the Emperor's identity as a Sith Lord and his Grand Plan to reinstate the Sith as the rightful rulers of the galaxy. A few years since his galactic conquest, he basically conquered most of the galaxy in 17 BBY as the ruler of his own powerful and updated incarnation of the, and annihilated almost more than half the allied forces of the Jedi Order (slaying notable Jedi such as Mace Windu, Depa Billaba, Kanan Jarrus, and Obi-Wan Kenobi) in the great conflict of Force-sensitives and other allied rebel organizations against the Sith that would be dubbed as the Dynamic Force Crisis.

During his seemingly longing reign as Emperor Sidious, approximately in 5 BBY, the Empire and the rest of the galaxy would later come to face a larger threat than themselves or the Jedi Order that has emerged from a neighboring galaxies in the forms of the ruthless and bloodthirsty Yuuzhan Vong, and other unnamed that proved a catastrophic threat to their galaxy. Thus, the Great Intergalactic Invasion broke out, temporarily ending the war of the Empire against those who still rebels against his rule, most especially the Jedi Order. The conflict would eventually meet its end in 0 BBY, as the final battleground of the intergalactic conflict takes place in the, which ended in the near-annihilation and defeat of the extragalactic invaders, albeit costing trillions of casualties in the galaxy.

However, even the Sith Lord's reign itself would eventually come to an end after he would be finally slain for good in late 6 ABY inside his flagship, the, by the prophesied , the now Jedi Master Anakin Skywalker, with the assistance of his newly-trained padawan and son Luke Skywalker along with an elite group of Jedi Knights who assisted the Skywalkers, during the force crisis' known final battle, taking place in the Unknown Regions, subsequently ending the reign of terror that the Sith and the Galactic Empire has unleashed upon the galaxy since 17 BBY.
