Jedi Master Anakin Skywalker

Was watching a what if Star Wars video on YouTube about what if Vader survived Return of the Jedi and though. What if Anakin lived  to see the event of Episode 7?
What if Anakin lived  to see the event of Episode 7?

After Luke save Vader, and he was taken to the medical station, while the Rebels, now the unofficial New Republic debate Vader's fate. 
When the Republic order his execution, Luke protest that he need to able to defend himself on trial, but he is overruled.
Luke try to delay, but is unsuccessful and take the matter into his own hands. 

When Luke goes break Vader out, he is confronted by aged rebel troop, reveal himself to be a former clone trooper, Captain Rex, and he will aid Luke his mission.

Luke and Rex take Vader to Kamino where Kaminoians offer him a new clone body, in honor for his serve in the Clone Wars. 
Anakin refuse,as he felt it dishonor the Jedi that he and the Empire killed. But does take treatment to on his skin so he does need the full suit.

While he no longer needs a helmet, he still is more machine than man. He wears a modified version of mask breath but now used his nature voice, unless he being authoritative.

For a while, Anakin completed Luke's training and named himself a Jedi Master. He and Luke started training a new generation of Jedi. When Leia sent a message that she was able to get a pardon for Luke and asked for him to return.

No such pardon is given for Vader.

Anakin tells Luke to return and to take the newer students with him, including his new wife Mara Jada.
But then when Han and Leia's son, Ben/Kylo Ren(who doesn't know that Anakin is still alive) killed the Jedi, including a pregnant Mara Jada.  
Luke return to Anakin, who was building his own order. As he felt both Snook and Kylo Ren present, as well of news of First Order.

 Together wait for Rey. 

And Together, will lead the final fight for the Balance of the Force.
