QUESTION: What are a Jedi's "powers" ? Has this ever ben authenticated in Canon? From what the films and TV series have shown, it's a mixed bag, and certainly ALL Jedi can't do EVERYTHING, and the list below would be best qualified as "Have the potential ability to..."
1) Using the Force seems takes a physical tole on the user, depending on the degree of the task involved. As seen in Tales of the Jedi when Yaddle dies, when Luke Force projects himself to fight Kylo Ren, when Doku fights Obi-Wan and Anakin in AOTC, when Grogu stops the Mudhorn attack and the Flametrooper attack.
2) Referencing the above, Jedi can Force project a doppelganger great intergalactic distances
3) Jedi can have "super speed" but really only seen once, in TPM with Qui Gon and Obi-Wan
5) Jedi can manipulate simple minded individuals, although certain non-humanoid species are immune (Watto, Jabba, etc)
6) Jedi can "cut" their connection to the Force (Luke, Obi-Wan), but then INSTANTLY REGAIN IT during times of intense stress
7) Jedi can communicate telepathically with other Force sensitive individuals
8) Referencing #1, Jedi can move physical objects with the Force/ telekinesis
9) Jedi can see the future, or at least possible futures
10) Referencing #10, Jedi have accelerated reflexes that are bolstered by their ability to see the immediate future event(s) about to occur (Anaki's pod racing skills, Yoda defending himself on Kashyyyk)
11) Jedi are experienced Cirque de Solei performers and can leap/fall great distances without bodily harm, by using the Force to both accelerate and decelerate their bodies as needed
12) Referencing #8 and #11, Jedi can levitate their bodies (Rey in ROS)
13) Jedi can hide their thoughts and true motives from other Jedi
14) Jedi can survive, for a short time, in the vacuum of space without any protective gear (Leia Poppins)
...anything major that I am missing here?
I think its hard to say because of three factors:
1) Jedi have different capabilities based on proficiency aka the number of midiclorians they have
2) Some have rare force powers that are unusual (possibly not canon since this isnt in the movies and is video game/book material)
3) Some stuff Disney just added
I think what we can say these powers are the base powers for jedi since they appear in OT, PT, and ST.
1) Manipulate objects with their mind (and outstretched hand)
2) Mind manipulate those of "lesser will"
3) Heightened reflexes and accuracy
4) Augmented physical capabilities (faster running, higher jumps)
5) A "connection" with the world around them that may allow them to "sense" things before they happen
6) Sensing other force users (telecommunication doesnt seem possible though for Jedi wouldnt have those devices)
7) Force lightning (Dark side only)
PT has been pretty consistent with OT in this respect in the movies. We do see some advanced combat using the force (throwing the lightsaber). The only "new" power we really see is force lightning absorption/nullification where Yoda is able to essentially redirect or nullify Dooku/Palpatine's force lightning. Dooku also has force levitation in the cartoons but we never see it in the movies. Books also state that Jedi and Sith put up "force shields" to protect them from a fellow force user pushing them or otherwise interfering with them using the force during a duel although this is not seen.
PT novels do introduce "unique" powers but these are special powers only specific jedi have such as "shatterpoints" for Windu that allow him to see "points of importance" that are weakpoints in combat or important figures or events in real time that attacking would dramatically change the timeline.
Video games introduced more offensive force powers like force pulse or energy absorption but since we never see this in any of the movies, we cant say for sure if these powers are canon.
Finally, ST adds a ton of new powers into the mix that makes things confusing.
1) Force stasis where Ren "freezes" the blaster bolt in place (also used by Cal in JFO)
2) Force projection by Luke
3) Force healing by Rey
4) Force space travel by Leia
5) Seeing the past by touching an object by Rey (also used by Cal in JFO)
Given its importance, force healing should be a very rare power that only Rey can use but since Ben kissed and revived Rey, who knows.
Since Disney owns the IP, technically everything shown in the movies is canon of what the jedi can do but Disney definitely added alot more flashy powers.
