Already in the previous Star Wars: A New Hope we had learned a lot about the powers of the Force: mind control, short-term foresight and a real mental connection between those who had embraced the Jedi way. Now, in the last expected Star Wars: The Rise of Skywalker new skills have been introduced.
Unfortunately, below you will find some spoilers, we have warned you.
The first and of the new powers is what concerns Kylo Ren and Leila Organa: if after the death of the princess her body does not disappear immediately (to join the Force like the previous Jedi masters ), this particular “transformation”, already shown in the previous ones chapters, it happens only after the death of Ben Solo, emphasizing not only how the bond between them is still strong, but also that the connection between those who manage to use the Force goes far beyond the earthly bonds.
In Star Wars: The Last Jedi, the audience saw Kylo Ren and Rey communicate with each other across the galaxy, even going so far as to see where the other was and interact with physical elements in their vicinity. In Episode IX this aspect is further accentuated to allow characters to transfer not only physical objects to each other but also to engage in a battle with lightsabers. Likewise, Luke’s ghost was able to grab the lightsaber that Rey threw at him.
Last, and perhaps most important, is the skill revealed by Palpatine and Rey before the final confrontation: if the emperor claims to have harnessed all the power of the Sith who came before him, the strength of the Jedi grows after hearing the voices of the old masters. Although it has not been clarified whether the two were the passive recipients of these skills or if they actively used them, it is certain that this connection had never been seen in the saga.
