This article is about the barrier between dimension. For other uses, see Hellmouth.

Hellmouth refers to an area in which the barriers between dimensions were particularly weak, allowing the creation of portals between Earth and several hell dimensions. For these reasons, the Hellmouth attracted demons and other supernatural creatures, becoming a "hot spot" for supernatural activity.


Hellmouths were created when a Deeper Well or Wellspring was used to cut a path to another dimension and allowing its magic to flow through.[1]


The word "Hellmouth" is derived from the original Spanish name for Sunnydale: Boca del Infierno, translated as "Mouth of Hell." While in this instance it refers to the city as a whole, it has come to refer to the center of this mystical convergence.


Distortions of the laws of physics were made possible by the Hellmouth's influence, such as Billy Palmer's nightmares intruding into reality and the ignored of notable monsters, such as the Master, the She-Mantis,[2] Moloch the Corruptor,[3] Machida,[4] Ovu Mobani,[5] and Balthazar.[6] A Suvolte demon also went to Sunnydale with the intent on breeding.[7]

According to Willow Rosenberg, the Hellmouth was responsible for the many churches located in Sunnydale as it made people "pray harder".[8] Spike took a severely weak and injured Drusilla to the Sunnydale Hellmouth in hopes that its energy would restore her to full strength.[9] It was credited for the hysteria that gripped Sunnydale following the First Evil's uprising, causing most of the population to flee and the Sunnydale police to resort to vigilante actions.[10]

Opening a Hellmouth posed apocalyptic threats predicted by portents, allowing demons to cross over to Earth. One such demon included a tentacled beast with multiple heads[11][12] and Turok-Hans.[13][14]

Known locationsEdit



Sunnydale destroyed after the battle in the Hellmouth.

The Sunnydale Hellmouth laid underneath the library of Sunnydale High School,[11] under the principal's office in its rebuilding.[15] The Seal of Danzalthar was the gateway, located in the school's basement.[16]

Spike used a magical amulet to destroy the First's Turok-Han army (as well as himself) and close the Hellmouth. The ensuing cataclysm not only collapsed the Hellmouth, but swallowed the entire town of Sunnydale along with it. As of spring 2003, the Sunnydale Hellmouth was permanently closed and inactive.[17]


After the Sunnydale Hellmouth had been destroyed, Rupert Giles mentioned Cleveland being known for having one as well.[17] For some time, it was guarded by a Slayer Organization squad led by Robin Wood and assisted by Faith Lehane.[18]

In an alternative reality, the Slayer Buffy Summers was sent to act in this town instead of Sunnydale.[19]

Easter IslandEdit

During the period of end of magic, the courtesan demon Morgan used a shard of the destroyed Seed of Wonder[20] to perform a ritual and open the Hellmouth located on Easter Island, Chile. Her attempt, though, was interrupted by Spike, who was then attacked by the Moai creatures guarding the place.[21]

Attempts at opening the HellmouthEdit

Behind the scenesEdit

  • The non-canon novel Dark Congress reveals the existence of a Hellmouth in Providence, Rhode Island, while the dubious canon novel Slayer features the creation and closing of a small Hellmouth in Dublin, Ireland.
  • The non-canon miniseries Spike: The Devil You Know has the vampire Tansy Fry opening an artificial miniature Hellmouth beneath Los Angeles, but it is destroyed.
