Force lightning/Legends

"A Jedi sufficiently strong in the Force can be trained to produce a facsimile, but not true Sith lightning, which, unabated, has the power not only to incapacitate or kill, but to physically transform the victim. Force lightning requires strength of a sort only a Sith can command because we accept consequence and reject compassion. To do so requires a thirst for power that is not easily satisfied. The Force tries to resist the callings of ravenous spirits; therefore it must be broken and made a beast of burden. It must be made to answer one's will. But the Force cannot be treated deferentially. In order to summon and use lightning properly, you will someday have to be on the receiving end of its power, as a means of taking the energy inside yourself."

- Darth Plagueis

Force lightning was a well known Force ability, most often used by practitioners of the dark side of the Force, especially the Sith. The ability was commonly referred to as Sith lightning, because of the usual users.

Description
"Some possess raw elemental power; they can unleash storms of lightning from their fingertips&hellip;"

- Darth Bane

Force lightning was a purely offensive, energy-based attack that channeled Force energy down the user's limbs, hurling arcing bolts of electricity from the wielder's fingertips or palms; Force lightning could be executed with either one or two hands. Powerful discharges would branch out into dozens of smaller forks; thus, skilled practitioners could target several foes at once.

The intensity varied based on a number of factors. A skilled user could render a target unconscious with only a short burst. A single, powerful blast was sufficient to kill a person instantly. Darth Bane's lightning, for example, would often electrocute his opponents to death on contact. Galen Marek was another Force-user who could channel lightning that would kill on contact. Both Kyle Katarn and Darth Sidious could conjure lightning so powerful that not only would it instantly kill its target, it would also physically hurl them backwards. The latter's usage was also powerful enough to render anyone caught in it into charred husks if used to its full potency, as demonstrated by his execution of Headmaster Gentis for his military coup against him.

The fact that it caused not only severe physical damage but also unbearable agony to the victim led to it being widely used as a form of torture. At the Battle of Endor, Palpatine repeatedly assaulted Luke Skywalker with lightning, and Darth Malak used it upon Bastila Shan, having captured her onboard the Leviathan and having brought her to Lehon, where he converted her to the dark side.

Depending on the level of intensity, Force lightning could ground itself on an ignited lightsaber, with no apparent ill effect on the lightsaber's operation. Powerful light-siders were sometimes able to resist the attack, or even block the lightning completely. Mace Windu, with his lightsaber combat form Vaapad, could reflect the lightning back to its source with a "superconducting loop". It required tremendous effort on the reflector's part, however, as seen in Windu's battle with Palpatine; Windu was seemingly able to overcome Palpatine's lightning. Obi-Wan Kenobi was also able to deflect Count Dooku's lightning, with his lightsaber, without exerting much effort as well. Galen Marek was capable of creating a shield out of his lightning, and could deflect even Palpatine's Force lightning back at him.

Force lightning could also be absorbed and redirected by a Jedi of sufficient skill; Yoda demonstrated this ability by both deflecting and absorbing the dark power during battles with Count Dooku and Emperor Palpatine, using nothing more than his own two hands. Galen Marek was also able to block Palpatine's lightning with only his bare hands while walking towards him. Luke Skywalker attempted this, and succeeded for a short amount of time, before the Emperor's attack overwhelmed him.

There existed an advanced version of Force lightning which may have been used by the Jedi Exile and Revan in the Jedi Civil War. Its destructive potential was legendary; the apocalyptic power was known as Force storm. Galen Marek used this power on the giant sarlacc on Felucia during his duel with Shaak Ti.

Galen Marek's clone, if in a rage, was able to produce lightning at such intensity that it literally vaporized his target. This is the most powerful known usage of Force lightning.

Effect of Force lightning
"The attempt on my life has left me scarred and deformed. But, I assure you, my resolve has never been stronger!"

- Palpatine

Though the short-term effects of Force lightning are obvious, the sheer power invoked by its use could have insidious long-term effects, both on those subjected to its power and those who would wield it. It deformed the person being shocked and it could also lead to them being crippled for the rest of their life. It was also known to cause brain damage and blindness. Prolonged exposure to intense electrical fields (such as a sustained current of Force lightning) caused most humanoids to experience sudden and massive calcification of their skeletal system; the abrupt drop in blood minerals provoked muscular micro-seizures all over the victim's body.

Telltale symptoms included generalized muscle aches and double vision. A blood test or bioscan could be used to confirm the diagnosis.

Unless the victim received complete bed rest and appropriate medical treatment, the disorder would become chronic, lingering for years (barring timely bacta immersion). Luke Skywalker, who was diagnosed with the disorder by 4 ABY was confined to a hoverchair for his trip to Bakura during the Ssi-Ruuk invasion, mere days after his near-fatal encounter with Palpatine.

It was thought that very intense use of Force lightning could drain the user physically, and possibly result in severe facial and body deformations. The deformities Palpatine displayed after unleashing a barrage of Force lightning on Mace Windu, only to have it reflected back upon him by the Jedi Master's lightsaber is an example of this.

When Anakin Skywalker redeemed himself and killed the Emperor, his life support circuitry was critically damaged, leaving him a heavy and lifeless quadriplegic.

Besides draining the user's energy, Force lightning had the added drawback of occasionally charring the hand of the person who used it. When Jacen Solo flew into a rage underneath the ruins of the Jedi Temple on Yuuzhan'tar and attacked his Yuuzhan Vong pursuers with Force lightning, he later found that the blasts had burned charred holes in his palm.

Very powerful blasts of Force lightning could highlight and illuminate the victim's skeleton, as shown with Mace Windu, Asajj Ventress and Darth Vader.

For unknown reasons, Force lightning (together with its various variants, such as Electric Judgment) was the only known Force power able to affect the Force-immune alien Yuuzhan Vong.

Use by Jedi
"Force lightning. We had thought Skywalker's Jedi considered themselves above that.''" "''We make exceptions."

- Welk and Mara Jade Skywalker

Force lightning ability was not restricted to dark-siders. Jedi and other light-siders who were strong of will and character could learn this power without falling to the dark side&mdash;but its use was viewed as inherently corrupting, and most Jedi Councils forbade its use. Some Jedi nonetheless refused to dismiss the natural power of this ability. During the Great Sith War, Jedi Master Lian Dray used Force lightning against the Sith apprentice Sindra. Revan, Meetra Surik, Jolee Bindo, Bastila Shan, and Vrook Lamar were amongst its users during the Mandalorian Wars, the Jedi Civil War and the First Jedi Purge. Plo Koon used this ability (which he called Electric Judgment) to subdue a criminal named Pommel, who had taken a hostage. Koon used Force lightning to knock Pommel out, yet claimed to have no plans to experiment with it in the future. Quinlan Vos could also employ this power effectively, and used it against the Anzat Jedi Volfe Karkko. Darrus Jeht also used Force lightning against the Dark Jedi Asajj Ventress.

Galen Marek was an extremely gifted user of this Force power, even after his conversion to the light side, rivaling Darth Sidious. He could kill foes with a single blast and was able to hit many adversaries at the same time. He was also able to deflect Force lightning with his lightsaber or even with his bare hands such as during the Battle on Death Star I. He could also charge objects and people with lightning and use them as improvised grenades, and to create a shield of lightning around his body to protect himself. Marek's clone was even more proficient, being able to set stormtrooper armor on fire with the power.

Some members of the New Jedi Order such as Kyle Katarn and Jaden Korr also used Force lightning (colloquially known as "Emerald Lightning"), but it remained very controversial. Other Jedi practitioners of this power have been Relin Druur, Kyp Durron, Jaina Solo (in a black variant respectively), Jacen Solo, Mara Jade Skywalker and Luke Skywalker.

Cade Skywalker was able to use Force lighting in a unique way. Utilizing his ability to see Shatterpoints in people and objects around him, he could use lightning to heal people, bringing them back from the very edge of death, or to kill them.

Force lightning users
"I've become more powerful than any Jedi. Even you."

- Count Dooku to Yoda

Force lightning required a living conduit for the energy to be channeled; thus Darth Vader, despite being an immensely powerful Sith Lord, was never able to properly employ this ability, as he was in danger of dying from it.

There was, however, one case where Vader did use Force lightning properly. When Vader was in close proximity to the presence of the Kaiburr crystal on Circarpous V, the amplification effects of the Force caused his affinity with the dark side to expand. As a result, Vader was able to utilize it's full power, a feat normally impossible for him.

Vader's cybernetics, as well as his artificial life support system, made him much more vulnerable to the damaging effects of Force lightning. This vulnerability would eventually contribute to his death.

Darth Sidious was a master of the technique. He used Force lightning to punish Luke Skywalker for his refusal to join him, beginning with an agonizing but non-lethal quantity and working his way gradually upwards toward lethality. When Anakin Skywalker turned on the Emperor, Sidious used the lightning at a much higher intensity, which eventually killed him.

Darth Tyranus used the technique to incapacitate Anakin Skywalker during the Battle of Geonosis. He also attempted the technique on Obi-Wan Kenobi, who was able to block it with his lightsaber, and Master Yoda, who managed to reflect and dispel the energy with his bare hands. In addition, Tyranus utilized this power to stabilize the heartbeat of General Grievous after the Kaleesh's body was mangled in a shuttle crash.

Darth Malak used Force lightning as a means of torture to turn Bastila Shan to the dark side. It was intended to give her a "taste" of the dark side's power, a technique that eventually succeeded.

Jorak Uln, the former headmaster of the Sith Academy on Korriban who hid in the Valley of the Dark Lords during the Jedi Civil War, would sometimes kidnap and torture Sith students. One of his favorite games was testing his captives on Sith philosophy, punishing their failure with Force lightning, often until they were killed.

Other Force-sensitives known to have used the power or its variants include:

Variants of Force lightning
"Power! Unlimited power!"

- Darth Sidious

Force shock
Force shock was a Force power that allowed the user to create an energy spark that would track and damage the nearest enemy. The shock could be thrown at an opponent to stun and injure them, or could be set loose to track an opponent until it dissipates. The shock would not last more than five seconds or so before disappearing into a tiny burst of heat, but it was a useful technique for Sith apprentices.

Force storm
Force storm was a Force lightning variant. The user would raise his palm upward and would create, through the Force, an explosion of electrical energy directed at all foes in the vicinity. It was used by both the Sith and Dark Jedi during the Jedi Civil War. It also appeared as a tornado of energy which created a great disturbance in the Force. Jedi could also join together to create a Force storm, though its use was frowned upon by more orthodox Jedi.

Unlike the Force lightning, Force storm was not limited to attacking enemies in one direction, as it affected all foes within a certain radius from the user. Revan and Meetra Surik may have mastered this particular power. Darth Bane and Darth Sidious were also notable users of this power; Bane being able to call upon a nearly uncontrollable Force storm shortly after having been taught the basics of Force lightning by Githany, who herself had only learned the power the same day from Qordis. Another notable possible user was Galen Marek, who unleashed the power several times, including on a giant Sarlacc during his duel with Shaak Ti in the Ancient Abyss.

Chain lightning
Chain lightning was a variation of Force lightning with the difference being that the lightning was able to strike one person and then move to another or several others. As it was more powerful than the standard lightning, it required a greater amount of discipline and concentration to project and sustain the stream of lightning. The only confirmed users are the Force apparition known as Dark Mara and Galen Marek and Count Dooku.

Sith barrage
Sith barrage was a variant of Force lightning that allowed users to create a bolt of lightning up from the ground damaging anything in its way.

Lightning Shield
Lightning Shield was another variation of Force lightning in which a shield of lightning covered and protected the user. Its effects could extend beyond the immediate space near the user, and could shock enemies in the distance. It could lower damage taken by the user, and could also enhance the saber damage the user dealt out. It was not the most powerful form of Force lightning, however; it still took mastery in the art of Force lightning and high concentration to use Lightning Shield. It could even redirect Force lightning back at another user of Force lightning. The only known users were Emperor Palpatine and Galen Marek.

Lightning Grenade
Lightning Grenade was a Force lightning variation in which the user gripped an opponent or object with the Force and lifted them up into the air. While the victim was suspended the user blasted them with a brief burst of lightning. The practitioner then either dropped the victim or slammed them into an object, causing the lightning coursing within them to explode. Galen Marek and Darth Sidious were the only known practitioners.

Lightning Bomb
A powerful variation of Force lightning. The Force user blasted an opponent with lightning, and then, using the Force, caused the lightning to amplify within the victim's body until it reached a critical point and exploded out of the victim. The explosion would also shock and kill anyone unlucky enough to be standing near the victim when the explosion occurred.

Sith Seeker
Sith Seeker was a very uncontrollable form of Force push. The Force user blasted the target with Force push, sending the object through the air. The user then generated a large ball of Force lightning. The Force user allowed the lightning to expand freely, until it was no longer under his or her control. They would then blast the Force lightning ball after the target, hence "Sith Seeker". The lightning exploded on impact with an opponent or object. The only known practitioner of Sith Seeker was Galen Marek.

Lightning Burst
Lightning burst was a variant of Force lightning, where the user would have ligtning arc out from their body to strike adjacent enemies.

Colors
While most Force Lightning manifested itself as blue, it could appear in several hues, though whether or not the color is distinctive was unclear. For example, Palpatine, Darth Bane and Kallig had all used purple lightning. The Hidden One used white. Talzin and Mother were seen using green. Dark side users like Darth Desolous, Darth Tenebrous, The Son and Luke Skywalker were seen wielding red. Jaina Solo also used a highly unusual color variant, in the form of black.
