Presença física de Voldemort pré-Cálice de Fogo

Esta explicação é dada em wikia Harry Potter :

After his escape from capture at Hogwarts, Peter Pettigrew(Wormtail) had no choice but to rejoin his master, or Sirius and Remus would surely kill him. He went to retrieve Voldemort's wand, then travelled to Albania where he learned from the rats there of a place in the forest where the creatures feared to travel. They said a dark shadow (Voldemort) took over the animals and killed them.

On his way to his master, Peter ran into Bertha Jorkins, a Ministry witch who was on holiday in Albania, while she had stopped at an inn for food. Although she recognised him, Pettigrew was able to lure her into the forest and overpower her, before handing her over to the Dark Lord. Under torture, Jorkins gave them information that helped Voldemort make plans for an attack on Harry Potter, including information on the Triwizard Tournament and the location of a faithful Death Eater. Voldemort's rudimentary body.

Pettigrew milked venom from Voldemort's snake, Nagini, to strengthen him and provide him with a rudimentary body. He carried Voldemort's weak, small body on the long journey back to Britain, where they took up temporary residence in the Riddle House outside of Little Hangleton. Voldemort called Peter by his Marauder name, "Wormtail." Over time, Pettigrew tried unsuccessfully to convince Voldemort to use a wizard other than Harry Potter to rebuild his body, but Voldemort saw this as an attempt at desertion and claimed that Pettigrew was regretting ever returning to him in the first place.

Não há explicação disso nos filmes em si, mas isso é explicado nos livros.

Menos que morto

É difícil responder exatamente o que ele foi depois de ter sido atacado por seu próprio Avada Kedavra, ninguém parece saber, com certeza. Esta é a explicação de Voldemort para seus Comensais da Morte:

“I miscalculated, my friends, I admit it. My curse was deflected by the woman’s foolish sacrifice, and it rebounded upon myself. Aaah... pain beyond pain, my friends; nothing could have prepared me for it. I was ripped from my body, I was less than spirit, less than the meanest ghost... but still, I was alive. What I was, even I do not know... I, who have gone further than anybody along the path that leads to immortality.

^{-Harry Potter and the Goblet of Fire, Chapter Thirty-Three (The Death Eaters).

Corpo rudimentar

Voldemort ganha um "corpo rudimentar" - a coisa esquisita infantil que Wormtail carrega - no começo de O Cálice de Fogo ; usando um feitiço de sua própria invenção junto com uma mistura de Blood Unicorn e O Veneno de Nagini .

Isso é discutido mais adiante em nosso Stack Exchange em Ficção Científica e Fantasia, em como Voldemort conseguiu seu corpo de volta?
