At the end of Revenge of the Sith, Anakin Skywalker is left in one of the worst situations imaginable. After losing the duel to Obi-Wan on Mustafar, he’s burned, mutilated, and lying helpless on the edge of a lava river.
For a brief moment, it really feels like that’s the end of him.
But then Palpatine arrives. He finds Anakin still alive, carries him onto the shuttle, and that moment leads to the creation of Darth Vader.
But here’s the darker question: what if Palpatine had looked at Anakin’s ruined body and decided he was no longer worth saving? What if, instead of rescuing him, Palpatine had simply left him there to die on Mustafar.
Anakin Would Live On Hating Not Just Obi-Wan, but Palpatine Too
So the first point is obvious. If Palpatine had decided to leave his new apprentice to die on Mustafar because he believed Anakin would never be as strong again, then yes, Anakin easily could have died from the injuries Obi-Wan left him with.
But the important part is that Anakin at this point is already completely soaked in the dark side. And in Star Wars, that matters. Even with injuries that should have killed him, Anakin’s hatred could still keep him alive.
That idea is already there in The Rise and Fall of Darth Vader, which states: ‘Only his hatred for Obi-Wan made him want to live another day.’
And if that kind of hatred could keep Anakin alive for Obi-Wan, then it could just as easily turn toward Sidious too.
Because from Anakin’s point of view, Palpatine was the one who promised him power. He was the one who made him believe he could save Padmé. He was the one who sent him to Mustafar to wipe out the Separatist Council. So if Palpatine then looked at what Anakin had become and decided he was no longer worth saving, that betrayal would give Anakin a second target for his hatred.
At that point, Obi-Wan wouldn’t be the only person Anakin wanted revenge on anymore. Palpatine would be added to that list too, and that hatred might be enough to keep Anakin alive just a little longer.
Anakin Might Have Rebuilt Himself from the Remains of the CIS Droids
Anakin would still have a reason to stay alive, but physically he would be in a terrible state. Both of his legs are gone, one of his arms has been severed, and the only limb he still has left is the mechanical arm he got earlier. In that condition, the only thing he could really do is drag himself forward.
And if he managed to keep going, the most likely place he would head for is the CIS facility on Mustafar. That base would still be full of leftover battle droids, machinery, and spare parts. So in a worst-case survival scenario, Anakin could try using whatever was left there to rebuild enough of his body to function again.
Of course, it wouldn’t be anything as advanced or polished as the Darth Vader armor Palpatine later gives him. It would probably be rough, improvised, and barely enough to let him move. But it could still be enough to keep him alive.
The bigger problem is time. Anakin’s injuries on Mustafar are far worse than anything Vader deals with later, so even if he had the materials to rebuild himself, his body would still need a long time to recover. That means this version of Anakin would likely be trapped on Mustafar for years.
And Star Wars actually gives us a version of this idea in canon.
In the Darth Vader (2020) comic series, starting right after The Empire Strikes Back, Vader begins searching for Luke after learning the truth about him. As that story unfolds, Palpatine senses Vader’s loyalty wavering and decides to punish him. He strips Vader of his mechanical limbs and abandons him on Mustafar, forcing him to survive on his own.
What Vader does next is the important part. He crawls his way back to the old CIS base and scavenges droid parts to rebuild himself well enough to keep going.
That’s why this comic works so well as proof for the what-if. If Vader could survive that kind of punishment later, then the same basic idea could apply here too. The difference is that Anakin on Mustafar would be much more badly injured, so rebuilding himself would take far longer, and his recovery would be much more brutal.
Anakin Would Begin Hunting Both the Jedi and the Emperor
If Anakin really survived Mustafar without Palpatine saving him, then his story would not end with him just trying to stay alive. Eventually, all of that hatred would need somewhere to go.
And at that point, Anakin would have two targets. The first one is obvious: the Jedi, especially Obi-Wan. From Anakin’s point of view, Obi-Wan is still the man who left him burning alive on Mustafar. That hatred was already strong enough to keep him alive in the first place, so it makes sense that revenge against Obi-Wan would stay at the center of everything.
And Palpatine wouldn’t escape Anakin’s anger either. Instead of becoming the controlled Darth Vader we know from the original timeline, this version of Anakin would be driven by a much more chaotic kind of rage. He would hate the Jedi for what they had done to him, but he would also hate Palpatine for using him and leaving him to die.
So if this Anakin ever managed to rebuild himself and leave Mustafar, he wouldn’t be returning as a servant.
He would be returning as someone who wanted revenge on both sides.
And that might be the darkest version of Anakin Skywalker of all, not a Sith apprentice, not a fallen Jedi, but a broken survivor with nothing left except pain, hatred, and a reason to make everyone pay for it.
