Force barrier

"Hold the flames back we will."
"How?"
"The Force is strong."

―Yoda and the Prime Minister of Protobranch^[3]

Force barrier was a defensive technique within the Force composed of Force energy, used to block out any potentially deadly elements. The technique itself was an offshoot of Telekinesis and was aligned to neither the light or dark side but was a neutral ability any Force user could learn and deploy.

During the Clone Wars, Jedi Master Aayla Secura and Grand Master Yoda used this power to stop a poisonous gas from reaching them as it was being deployed against the Zillo Beast.^[1] Darth Vader used this ability on several occasions to protect himself from environmental hazards like falling debris, oceanic pressure from being submerged in the depths of Mon Cala, and explosions of fire or shock-waves.^[4] Kanan Jarrus used a barrier of Force energy to hold back an explosion, saving his fellow rebels before his death.^[5] Ezra Bridger, Ahsoka Tano,^[6] Tenth Brother, Sixth Brother, and Ninth Sister also used this power.^[2]

Kanan Jarrus holds back an explosion with a Force barrier.

While escaping from Fortress Inquisitorius on Nur, Cere Junda projected a barrier to prevent Darth Vader's lightsaber from harming her and Cal Kestis. Vader attempted to stab through it, partly succeeding, until Junda and Kestis escaped. Shortly thereafter, Vader used a barrier to stop seawater from engulfing him.^[7]

In 9 ABY, Grogu, an infant force-sensitive member of Yoda's species, used a form of the technique to hold back and deflect a blast of fire coming from an Incinerator trooper.^[8]

In 34 ABY, Kylo Ren instinctively used a version of this technique and his Force Stasis ability to stop Chewbacca's bowcaster bolt from causing fatal damage and killing him.^[9] He used Force barrier during his ship crash on Pasaana and also on a planet in a ship with Hux, which in both cases left him unharmed.^[10]^[11]
