Anakin survived because of his pure rage and hatred. The dark side of the force kept him alive

The Dark Side works in mysterious ways.

I mean Palpatine survived the Death Star 2 explosion and Darth Maul survived getting his feet chopped off, how does he use the bathroom?

Anakin’s own hatred combined with Palpatine’s contributions prior to taking him back to coruscant helped him stay alive. On top of that he was also fighting to stay alive because he still had something to live for (or so he thought).

Well I mean if he didn't survive the burn then he wouldn't be Darth Vader

I don't know if Palpatine would be able to revive Anakin

Sure a normal human would have died from the burns but I guess Anakin had a strong Force ability or something to make him survive

Def. Anakin wanted to survive (atleast until he realized that Padmé died) he was strong dnough in the dark side through his pure hatred and rage to survive until Palps saved him. So yeah it makes sense.

It’s a similar story to that of Darth mauls from TPM, he used all his hatred and anger to prolong his life.

You could argue the logic but it’s Star Wars 🤷‍♂️

Same with Darth sion, he was able to save himself from death and even piece his body back together because of the sheer power of his hatred
