Fire is a method of killing that involves the burning of a subject with an open flame. This is a method which can be used to harm supernatural species; such as vampires, werewolves, hybrids and witches. The most common way this method is used usually involves restraining the movement of the subject, dousing them with an accelerant before lighting them on fire. Thus, killing them from immolation. Witches are able to cause spontaneous combustion through witchcraft and spells.

Hellfire was a supernatural, psychic fire originating from Hell. It was incredibly powerful and capable of destroying anything within its path. After the destruction of Hell it remains unknown if it's possible to recreate it.
Hellfire was created when Arcadius was killed and, unleashing a powerful psychic blast, created an imprint of his death (burning at the stake). Ever since, it's been used to torture souls in hell. Hellfire became able to be released upon the earth when the Bennett Coven's mystically imbued bell was corrupted by a sirened Ethan Maxwell with the Staff of Arcadius. The amplified properties of the staff made it possible for the psychic walls of Hell to be breached with 12 rings by an individual from the Maxwell bloodline.
- Mystical Energy: According to Alaric and Bonnie in I Was Feeling Epic, hellfire possesses "a few million volts of mystical energy", enough energy to effectively destroy hell. This was proven true when Bonnie and the Bennett ancestry redirected hellfire back into hell, destroying it.
- Massive Destruction: Hellfire is capable of consuming anything within miles of where the bell was rung and has almost destroyed Mystic Falls twice. In order to stop it, it was necessary to utilize the magic of the entire Bennett Coven.
To date, Arcadius has been to only known Psychic able to manipulate fire, specifically Hellfire. This, seemingly, stems from the fact that Hellfire was tied to his personal psychic dimension, Hell, as he only gained this ability after his first death. In Nostalgia's a Bitch, Seline explained how the world Arcadius created was a massive psychic imprint of the moment of his death, making his domain a ball of fire. She also stated that hellfire could kill a Siren. Sometime after the the Maxwell Bell rang eleven times, Arcadius appeared and used his hellfire to kill both Sybil and Seline, confirming the power embodied in hellfire. In What Are You?, Arcadius used hellfire to ignite the Maxwell journal, rendering it into ash. In I Was Feeling Epic, Katherine planed on destroying Mystic Falls with hellfire by having Vicki Donovan ring the Founders Bell. Bonnie, however, was able to contain and redirect the hellfire to the Armory. There, Bonnie struggled to hold the fire at bay, though Sheila Bennett and other members of the Bennett Ancestry came from peace to aid Bonnie and, together, they destroyed Cade's Hell.
- Original vampires cannot be killed with fire as mentioned by Elijah.
- However, when stabbed with the White Oak Stake, the flames produced will kill them. However, if the flames can be extinguished, as in The Departed, then the Original can survive. The caveat of this scenario, however, is that Klaus' spirit was not in his body and was possessed by the hybrid Tyler. In Red Door, it is proven to be an important component to the white oak stake's killing power.
- It is unconfirmed if fire can kill hybrids. However, Tyler Lockwood, a hybrid, mentions that the only way to kill him is through decapitation or heart extraction, so this remains unclear.
- Despite their ability to control fire, witches are able to be burnt to death.
- Naturally, vampires and Original vampires burn in the Sun. Vampires will indirectly die from the fire that is produced if they're not extinguished.
- According to Katherine, hellfire is "so intense, it could obliterate anything within miles." The validity of her statements, however, remains unclear, especially in the regards to destroying an Original vampire, which has not been demonstrated.
