The Chosen One appeared in the last two episodes of the Star Wars miniseries but some of his powers are new.

As known to fans of Star Wars, Hayden Christensen he returned as Anakin Skywalker in the last two episodes of Ahsoka, the new miniseries starring Rosario Dawson. However, the Chosen One showed off some new powers and a fan tried to explain it his way.
For the first time in the saga, we see Anakin seamlessly transition from light to dark and back again, and he also seems very comfortable in the mystical World Between Worlds. Why these new skills? It’s a mystery for now, but one fan has a very convincing theory tied to the Clone Wars mythology.
To get into the merits of the theory, we must first explain Mortis. In The Clone Wars, Anakin, Ahsoka and Obi-Wan Kenobi end up in a strange supernatural realm called Mortis. There they meet three deities of the Force: the Father, the Son and the Daughter. The Son is aligned with the dark side, while the Daughter is aligned with the light side, and the Father is the balance between both.
The Father wants Anakin to take his place, as Anakin is the Chosen One. Anakin, however, refuses and leaves and, as the ship departs, the Imperial March plays ominously in the background. The story, however, does not end there: the trio returns to Mortis in the following episode. The adventure ultimately leaves the three gods dead, but they appear again on a mural in Star Wars Rebels at the entrance to the World Between Worlds.

What does all this have to do with Ahsoka? Well, one fan speculated that Anakin took over from the Father in the end.
After explaining that the Anakin we see in the episode is “vaguely as we once knew it“, user lexE5839 wrote: “However, I believe that He ascended and became the Father. His ability to switch between the light and dark sides at will, have a completely tangible body in the World Between Worlds, and even summon Ahsoka in physical environment simulations of past battles they fought together would indicate that he has enormous power. . This is purely my canon, but I believe that Anakin saved Ahsoka from death, perhaps because he chose it, but if he really is the Father it was probably the will of the Force“.
Reddit user calls Anakin a “true master“, capable of using both the light and dark sides in a way unprecedented for Star Wars.”The Father seemed to have unparalleled mastery of the will of the Force, and his children were the balance between good and evil“, let’s read.
“I like to think that in the eyes of the Force, Anakin served his destiny by destroying both the Jedi and the Sith, then allowing both to rebuild. His downfall as Vader and his subsequent redemption proved that he wasn’t entirely light or dark. As Father, Anakin would follow the will of the Force and ensure balance in the universe, guiding those who need it to their destinies“.

You believe that this “it would be a touching and fitting fate for the Chosen One, and would prevent tampering with his sacrifice like Vader“, and believes that “is transcended into a being who maintains the balance of the Force he created“.
