What happened to Voldemort's body when he destroyed the last Horcrux?

It might have just rotted and been eaten by birds

bird: Yummy who are we eating
bird2: the most evil dark wizard ever
bird; *gulps and flies off*

Harry WAS the last hrocrux and nothing happened to the body, the piece of his soul in there was seperate and it's destruction only ended Voldemort's immortality thus allowing Harry to kill him. And I think Harry came back to life because after ending his existence as a horcrux his being as a human came back into play

They put him in the bin!

Well, there's a fine question. Grawpy tried to eat him at firs' but we were worried that 'is spirit might come back or something. So what did we do? We burn 'im, didn't we? And chuck 'im in the good ol' black lake. Gives me the collywobbles though!

The elves secretly took it and cooked it... no fist years... that's NOT beef you're eating ;)

All that matters is....HE'S DEAD!

i dont know. not at hogwarts yet.

You meant when Harry destroyed the last Horcrux ?
Voldemort became human again, in the physical sense of the term. He just died like the countless victims he had killed with an Avada Kedavra, when his curse intended to Harry, backfired on him. End of the story.

After, maybe Voldemort's body was burnt. Fire purifies many things.

its body dissepeared along with him
