History Main / LifeEnergy

* ''Manga/{{Bleach}}'' makes this what constitutes all souls, including nonliving things. Hollows can increase their amount of it by eating other souls, including (and especially) each other. Quincies can increase it by forcefully breaking down their surroundings and absorbing them. Soul Reapers have various ways to increase how much of it they have, but no special feature to speak of. However, unlike normal human souls, they must eat, and they release their spirit energy constantly. An anime filler arc features vampire-like creatures called Bount, which drain the life force out of their victims (directly) as opposed to blood.

It's connected to [[OurSoulsAreDifferent souls]], HermeticMagic, KiAttacks, PsychicPowers and other superpowers; see also {{Mana}}. In RolePlayingGame terms, it's the combination of Hit Points, Magic Points, and Experience. Transferring it may cause physical changes that are LiquidAssets. Occasionally, part of an EquivalentExchange to power an ArtifactOfDoom or EvilWeapon.

** In Bujold's ''TheSharingKnife'' books, Lakewalkers' magic is all about the manipulation of Life Energy.

* Goes by the name ''Power of Existence'' in ''ShakuganNoShana''. Losing any amount of it turns a human into a Torch at best, doomed to eventually [[RetGone have never existed]].

* [[Wiki/SCPFoundation SCP]]-[[http://www.scp-wiki.net/scp-1716 1716 ("Imperfect Life Extender")]] is a device that transfers life energy from one person to another.

[[folder:Web Comics]]
* [[OurVampiresAreDifferent Tristram's]] power in ''Webcomic/{{Earthsong}}'' is the draining and replacement (thereby, healing) of Life Energy.
* In ''Webcomic/{{Thunderstruck}}'', it is explained that vampires don't feed on blood per se, but on the Life Energy it carries.
* Medicine in ''Webcomic/GirlGenius'' seems to rely on "Galvanic energy," which is usually fed through big machines, or from the waters of the [[MeaningfulName Dyne]].

* The Parasite in ''WesternAnimation/SupermanTheAnimatedSeries'' is basically a male villainous {{expy}} of [[ComicBook/{{X-Men}} Rogue]]. Humans usually wind up unconscious and twitching a little. He can also gain access to their memories, and [[VoicesAreMental sound like them]]. When he does it to [[SuperEmpowering Superman, however...]]
** The Parasite is hardly an expy of Rogue, as he is far the older character; he was around in the 60s.

* This may be what the planet-eating {{Galactus}} in MarvelComics feeds on.

Not to be confused with [[VideoGame/{{Gradius}} the NES space jet game of the same title]], or the 1985 sci-fi movie ''Film/{{Lifeforce}}''.

** ''{{Spelljammer}}'' also included lifejammers -- a spelljamming helm was a chair which allowed one to pilot a vessel into space by draining spell energy; a lifejamming helm ... well, you can figure it out from there. Lifejammers were particularly popular among evil beings such as neogi and undead, who were fond of subjecting their slaves and captives to this. Lifejammers ''could'' be used by volunteers, since they only drain 1d8 hit points per day... a high level party could easily take this in turns and heal back up in between. Unfortunately, there's also the daily DC13 save or die; no matter what bonuses you have, someone's ''eventually'' going to roll a 1, and that's going to be bad. The manual points out that some Lifejammer captains prefer tough creatures with lots of HP, while others go the "endless supply of expendables" route.

* ''JonnyQuest'' TOS episode "The Invisible Monster". The title creature can eat any kind of energy, including that found in a living body. Near the beginning it consumes both its creator Dr. Isaiah Norman and a native villager.

* ''KeyTheMetalIdol'' has a CorruptCorporateExecutive engage in Life Energy harvesting far more effectively than the Dark Kingdom ever did. For example, random people at rock concerts, where it's expected for there to be fainters.
* ''MagicalGirlLyricalNanoha'''s second season had the antagonists stealing magical power from mages (magical beasts when they could, though) in order to complete "the Book of Darkness." Fortunately, people can recover from that, and depending how young they are, their powers can also completely replenish.

* ''{{Bokurano}}''. The giant robot is powered by the Life Energy of the pilot. [[spoiler:Win or lose, the pilot dies after the battle -- it just isn't followed by the ''the entire universe dying'' in case of a win.]]

* Tenshinhan from ''DragonBall'' and ''Dragon Ball Z'''s signature technique [[CastFromHitPoints uses his life energy]], making it one of the most powerful techniques in the series.
** Goku's ultimate technique, the Spirit Bomb, draws in small amounts of life energy from everything around it and unleashes it in a huge explosion.

* ''TabletopGame/{{Champions}}'' adventure ''Wrath of the Seven Horsemen''. The villiain Dread is a summoned wraith that can drain the life force of opponents and thus lower their Constitution score for the duration of the adventure.

* ''{{GURPS}} Aliens''. The Gloworms feed on LifeEnergy by touching other living creatures. They can feed on animals but prefer sentient victims.

* The title creatures from ''{{Metroid}}'' drain the life energy from any animal unfortunate enough to encounter it. The SpacePirates tried to use science to explain the phenomenon, but could find absolutely no trace of this "life energy", only the proof that ''something'' vital was obviously being drained.

* Raziel from the ''LegacyOfKain'' series typically feeds on the souls of the slain, but he can also snack on friendly humans. If he only drains a little, they'll get tired but eventually recover. Too much and they'll die, and then the other humans stop being so friendly.
* Life Energy was first offhandedly mentioned in the ''FireEmblem'' series in ''Genealogy of the Holy War'' under the name Aegir, but had a much bigger role as the BigBad's main power source in the seventh game, where its name was localized as "Quintessence".

** ''[[FateStayNight Fate/stay night]]'': the Mages (Masters) and their Servants have the ability to manipulate the life energy of others (mana) both willingly and [[BlackMagic unwillingly]].

** Lackey's ''Children of the Night'' has '[[OurVampiresAreDifferent psi-vamps]]' who drain energy from others. In this case the energy is [[EmotionEater tied to emotions]] -- they drain excitement at first, and later hate and fear. Also, a completely drained victim is usually not physically dead, but is [[TheStoic emotionally/mentally burned out]] (described as a mindless hulk, with no chance of recovery).

[[folder:Pinball]]
* Creator/{{Capcom}}'s unreleased ''Pinball/{{Kingpin}}'' has the Power Meter, which is built up during regular play by making Power-Up shots. At the end of the last ball, the game enters "Sudden Death", where play continues while it runs down, with the flippers becoming slower and weaker as it decreases. Making more Power-Up shots add more Power and playtime, but once it's depleted, the flippers die and the game ends.
