Star Wars: Jes Gistang the Female Stormtrooper

Presenting Jes Gistang, the only NAMED Female Stormtrooper in the entire Star Wars saga. There was actually another female Stormtrooper who appeared in issue #0 of Star Wars: Legacy but she was unnamed. Prior to Star Wars Legacy, there is no mention of women serving as Stormtroopers in the Empire. Agents, yes; pilots, yes; techs, yes; Hands of the Emperor, yes; but no Stormtroopers.  

But then what do you expect from an organization built on the premise of the generic superiority of "humans" over "aliens?" Gender Equality definitely has to fly out of the door.

Anyway, better late than never. Jes Gistang was a member of Joker Squad: Company C, 9th Battalion of the 407th Stormtrooper Division under, first, the Fel Empire, then later under Darth Krayt's One Sith Empire.

I'm not really sure why they were called "Jokers" but they do get killed a lot. Sadly that includes Jes Gistang dying while assaulting the 908th Stormtrooper Division's fortress on Borosk. The 908th consisted of Stormtroopers who remained loyal to Emperor Fel, so naturally they had to be wiped out. Jes Gistang met her end in the heavy fighting when a stray blaster bolt hit one of her exposed Powek Paks and she blew up. Which is sad because Jes Gistang didn't want to be in the battle and tried to convince the rest of the Jokers to defect or leave the battlefield.

STAR WARS: Darth Nihl (Legacy series)

Presenting Darth Nihl of the One Sith Empire from the STAR WARS Legacy Series. Darth Nihl is a member of the Nagai race - a race of near-humans with pale white-skin and sharp features (often thought to be walking dead-humans) - also known as "Knives". They come from the planet Nagi from the Firefist Universe - one of the closest universes to the main STAR WARS universe that is still currently classified as "Unexplored" though the Nagai have actually tried several invasions and member of the Nagai have long traveled the STAR WARS universe, some of whom actually became Jedi.

Darth Nihl chose a different path obviously.

Darth Nihl was recruited by Darth Krayt for his One Sith Empire, initially serving as a "Fist"or warlord. Eventually however - given the more... "expansive" yet heretical view of how the Sith should be organized by Darth Krayt, Darth Nihl was eventually promoted to the rank of "Hand" (A position he would have to begrudgingly share with Darth Talon.) Upon becoming Darth Krayt's hand, Darth Nihl would lead an attack on the Jedi Praxeum on the planet of Ossus where he would find himself in battle against, among others, Jedi Master Wolf Sazen who would severely wound him (At the cost of an arm). Before his battle with the Wolf though, Darth Nihl was able to kill Kol Skywalker, ancestor of Luke Skywalker and father of Cade Skywalker - who was presumed dead after the destruction of the temple and who would later resurface as a bounty hunter.

STAR WARS Legacy of the Force: Imperial Knight Masters Sigel Dare, Antares Draco and Ganner Krieg

Presenting Imperial Knight Masters Antares Draco, Sigel Dare and Ganner Krieg from STAR WARS Legacy of the Force.

Imperial Knights are an order of Force Sensitive Jedi that served the Empire-in-Exile (Formerly known as the Fel Empire) - a long, long time ago after Luke Skywalker had become one with the Force. They were formerly known as the Knights of the Empire till Darth Krayt's One Sith Empire came to power and kicked them out.

They were founded because Jagged Fel - squeeze of Jaina Solo - thought that it would really be great if the  Imperial Remnant had Jedi Knights.

In essence, Imperial Knights are trained Jedi who instead of being loyal to the ways of the Force, swear fealty to the Emperor of the Empire BUT with the clause "As long as he serves the Light Side of the Force." Because of this they were rejected by the Jedi Order and considered "Gray Jedi" - or Jedi who rejected the Dark Side of the Force but did whatever was necessary to bring "Order and Peace to the Galaxy" (Very Anakin Skywalker, but think of them a bunch of Qui Gon Jinns who "Do what they must" with or without the council's permission).

With the fall of the One Sith Empire and the rise of the Galactic Federation Triumvirate led by Admiral Gar Stazi, Jedi Master K'Kruhk and Imperial Knight and heir to the Fel Empire, Empress Marasiah Fel, the Imperial Knights remain separate from the Jedi Order, but now consider them allies - for now.

STAR WARS Legacy of the Force: Cade Skywalker

Presenting from STAR WARS Legacy of the Force, Cade Skywalker from the Legacy of the Force 2-pack that included Darth Talon.  Cade Skywalker is assumed to be the Grandson of Ben Skywalker - son of Luke Skywalker - son of Anakin Skywalker. So that makes Anakin from STAR WARS Episode 1 his Great-Great Grandfather. Cade's father Kol, and uncle, Nate, were Jedi Masters and members of the Jedi Council when the One Sith began their rise to power.

For the uninitiated  the One Sith is a deviation from the traditional Sith philosophy called the rule of 2 that was initiated by Darth Bane. If you've played STAR WARS Old Republic, then you know that the Sith used to be as plentiful as Jedi - to the point that they had their own training temples. Then Darth Bane happened and he said that there should only be two: A Sith Lord who has power, and an apprentice who covets power. And this has been how it's been for nearly a millennium. Former Tatooine Jedi Knight A'sharad Hett who fell to the Dark Side and thought that the Rule of 2 was stupid and weakened the Sith especially in face of Luke Skywalker's Jedi New Jedi Order army. So he blasphemed, named himself Darth Krayt and created the Rule of One: One with total power, with an army of followers behind him. 

Darth Krayt went to overthrow the Galactic Alliance, establish a Sith Empire, send the Jedi Order into hiding, and traumatize Luke Skywalker's Great-Great-Grandson into leaving the Jedi Order. Cade Skywalker and becoming a bounty-hunter/pirate  who sometimes hunts Jedi.
