"They are corpses, dead bodies that have been bewitched to do a Dark wizard's bidding. Inferi have not been seen for a long time, however, not since Voldemort was last powerful.... He killed enough people to make an army of them, of course."
Albus Dumbledore on Inferi[src]

An Inferius (plural: Inferi) is a dead body, reanimated by a Dark Wizard, similar to a zombie. They have no free will, and cannot think for themselves; their purpose is merely to serve as puppets of the Dark Wizard who reanimated them. They were used by Lord Voldemort in both the First Wizarding War and the Second Wizarding War. It is mentioned that the dark wizard Gellert Grindelwald also sought to create an army of Inferi. It is unknown as to whether he succeeded. Inferi are created through the magical branch of Dark Arts called Necromancy.[1]

Physical Description

The Inferi are gaunt, skeletal beings that resemble closely to zombies. They are known to have large strength and are powerful to kill a human being.

Defence against Inferi

Because Inferi are creatures of the dark, they dislike light and heat. The most effective spell against them is therefore a fire-summoning spell, such as Firestorm. Other spells might work against a few Inferi, but might not be useful against a whole army of them. It must be noted that Inferi are resistant to most spells: they cannot feel pain, and thus are unaffected by many attacks whose main effe

ct is pain such as the Cruciatus Curse. This is evident when Harry Potter attempts to use the dark spell, Sectumsempra on the Inferi in the Horcrux cave, as they have no blood to spill.[2]

In 1997, Harry Potter and Albus Dumbledore encountered this very same army of Inferi in their attempt to steal one of Voldemort's Horcruxes. Dumbledore successfully repelled them by conjuring a ring of fire, big enough to surround both Harry and himself.

Other encounters

Not exactly counted as a real encounter, but worth mentioning: Mundungus Fletcher was arrested and put into Azkaban because he disguised himself as an Inferius after being caught during a burglary at Sirius Black's house.[2]

The Ministry warned the community that Voldemort may be using Inferi once again in the Second Wizarding War, and he was mentioned that he did use as much as an army during the First War.

Regulus Black was also killed by Inferi in his attempt to destroy one of Voldemort's Horcruxes.


"Inferius" is Latin for "underneath; below." It could also be a tampered form of "inferus", or "the dead; underworld." As J. K. Rowling sometimes changes real Latin words to form some incantations, or names of creatures or people, it could well be that the second meaning is the correct one.

Behind the scenes

  • According to W.O.M.B.A.T., Inferi may have the ability to speak.
  • Inferi may have been briefly referred to by Voldemort in the Little Hangleton Graveyard as part of an "army of creatures whom all fear".
  • Inferi may be incredibly strong as a picture in Snape's DADA class shows a bloody mass on the floor, attributing to a person provoking the anger of an Inferius. Alternatively, this could be attributed to their viciousness and implacability.
  • It is unknown if there is any difference between Inferi and zombies, as they both seem to be reanimated corpses.
  • In first part video game adaption of Harry Potter and the Deathly Hallows, Inferi appear again, despite them not being in the mainstream storyline.
  • The Inferi in the Half-Blood Prince film resemble Gollum from the Lord of the Rings film trilogy, except they are taller and more gaunt.
  • If the singular form is inferius, then using Latin rules, the plural should be inferii (in-fer-ee-eye), not inferi.
