[[caption-width-right:304: While we appreciate your willingness to donate, we aren't sure whether your blood type is compatible.]]

Characters with Volcanic Veins have a form of biological TronLines where their veins and arteries will [[PowerGlows glow intensely]] from underneath the skin, sometimes even "pulsing" in tune with their heartbeat or as if they had real magma flows inside their bodies. It should come as no surprise when dealing with characters who are {{elemental embodiment}}s of fire and lava -- where it gets interesting is that this can be used for just about any biology and power set. [[AnIcePerson Ice powers?]] Neon blue jagged veins. Ability to manipulate PureEnergy or {{Mana}}? Holy white veins. [[PoisonousPerson Control over poisons]]? Sickly green veins (which you probably ''really'' [[BloodyMurder don't want to bleed on you]]). A BlackMagic master who's DrunkOnTheDarkSide? Malevolent [[PurpleIsTheNewBlack purple veins]].

Thanks to PsychoactivePowers the veins will glow proportionally strong to the character's health and emotional state. Much like EyeLightsOut, if the character dies you can expect their Volcanic Veins to "dry up", darken, and maybe even harden like cooling lava. It should be noted that artists may not have done the research and draw Volcanic Veins over places or in directions normal surface veins don't go. In these cases it may be that their "magical chi flow" doesn't necessarily have to be identical to their biological blood flow.

Compare VeinOVision and XRayVision. Contrast TaintedVeins. See also ThroatLight.



[[folder:Anime & Manga]]
* Members of the Vandenreich in ''Manga/{{Bleach}}'' sometimes show these when using Blut Vene to defend against attacks.
* In ''Anime/UmiMonogatari'', those corrupted by Sedna have these, particularly on their legs, arms, and face.

* Both Finnegan and Gloriana in the Top Cow series ''Broken Trinity'' starring the ''Comicbook/{{Witchblade}}'' and ''ComicBook/TheDarkness'' have Volcanic Veins. In Finnegan's case they're bright blue and ice power based. Gloriana has magma red veins.
* Bane is sometimes depicted as having glowing green pulsing veins when he injects the venom that gives him his strength.

[[folder:Fan Works]]
* In ''Fanfic/TheBridge'', Enjin has magma hued runes and veins going across its body in both its true and humanoid form. This is to mesh with its role of Aspect of Land. Mizu, the Aspect of Sea, has icy blue markings in the same manner.

[[folder:Film - Animated]]
* Near the end of ''Disney/AtlantisTheLostEmpire'', after Rourke is transformed by the crystal's power, there are several bizarre glowing red veins visible all over his crystalized body.

[[folder:Film - Live-Action]]
* The subjects of the Extremis program in ''Film/IronMan3'' have this. Fittingly, they actually have heat based powers.
* A lot of the {{Kaiju}} from ''Film/PacificRim'' posses this, such as [[ExactlyWhatItSaysOnTheTin Knife]][[WarmUpBoss head]] and [[FatBastard Leather]][[{{EMP}} back.]]
* Bishop does this when using his mutant ability in ''Film/XMenDaysOfFuturePast''.
* ''Film/DieMonsterDie'' has an early example, when Creator/BorisKarloff is overcome by the meteor's mutating radiation.
* In ''Film/ThorTheDarkWorld'', the Aether infects Jane and causes her veins to glow red when she's examined by Odin.

* In ''Literature/{{Animorphs}}'' #26, the alien race known as the Howlers has these. For extra points, their skin has the texture of dried lava.

[[folder:Live-Action TV]]
* Geordi was infected by a parasitic species in the ''Series/StarTrekTheNextGeneration'' episode "Identity Crisis". Those infected turned into invisible aliens that could only be seen under UV light. When exposed, they had neon blue veins.
* Used in a ''Series/OneThousandWaysToDie'' anecdote about a rave attendee who got so wasted that he tried to mainline the luminous fluid from a glowstick. Justified in the anatomical animations, although the fluid's light probably shouldn't have been visible through his skin in the live-action scene.
* The Eidelons in ''Series/{{Farscape}}''; the occasionally glowing "veins" are actually the segmented parts of their faces which they can split open to reveal their empathic organ (one wonders where they keep their brains?).
* In season seven of ''Series/{{Supernatural}}'', Castiel briefly sports bright, glowing ''red'' veins (and eyes) when [[spoiler:he transfers Sam's [[ImHavingSoulPains Hell-induced mental agony]] to himself]] to save Sam's life.

[[folder:Tabletop Games]]
* Genasi (D&D version 3 onwards) have glowing lines on their bodies, unique to them and a sign of whatever element they are manifesting.
* ''TabletopGame/MagicTheGathering'''s [[http://gatherer.wizards.com/pages/Card/Details.aspx?multiverseid=212238 Koth of the Hammer]]. Fitting too, since he's a [[DishingOutDirt geo]]/[[LavaAddsAwesome lavamancer]].
* The [[http://www.wargamer.com/files/articles/2661/20090225101740.jpg Avatar of Khaine]] in ''TabletopGame/{{Warhammer 40000}}''

* Adam Power, Shaya, and the Trigore from the ''PowerLords'' line of action figures.

[[folder:Video Games]]
* The PC's tattoos start doing this in the ''VideoGame/{{Fable}}'' series if you use magic often.
* The boss Fyrus in ''VideoGame/TheLegendOfZeldaTwilightPrincess''.
* ''VideoGame/BioShock:''
** In ''VideoGame/{{BioShock|1}}'' this trope is invoked on the protagonist's veins quite frequently, depending on the plasmid at the time. It's surprisingly well researched too.
** It's used less often in ''VideoGame/BioshockInfinite'', in favour of more visible external mutations of Booker's hands, but it still appears as part of the Charge Vigor's manifestation. It can be seen with Shock Jockey too, but only at certain angles.
* ''VideoGame/EtherOne'' gives its protagonist glowing blue veins when using their memory-restoring device.
* Groudon, Kyogre, and Rayquaza in ''Pokémon'', with their veins prominently pulsating in the title screens of ''VideoGame/PokemonRubyAndSapphire''/''Emerald'' versions. Groudon manifests the "volcanic" part a bit more, since it rules over land and lives in a volcano. Groudon and Kyogre's [[SuperMode Primal Reversions]] take this [[UpToEleven even further]] with Groudon's veins full of lava and Kyogre's much more pronounced, [[PowerGlows glowing bright yellow]].
%%* The [=TzHaar=] in ''VideoGame/RuneScape''.
* In ''VideoGame/BatmanArkhamAsylum'', Bane and the Titan Henchmen have glowing green Venom/Titan pulsating throughout their bodies.
* Anders in ''VideoGame/DragonAgeII'' manifests these and GlowingEyesOfDoom whenever Justice/Vengeance asserts itself.
** Should a Mage Hawke specialise in Blood Magic, they get these.
* The Drakes from ''VideoGame/BattleForWesnoth'' normally have green scaled skin, but the Burner family, with their stronger connection to their inner fire, have gray skin. As their fire gets stronger, it shows more and more through their scales and their veins that they eventually become blazing red, as in the case of Inferno and Armageddon Drakes.
* Nano-soldiers in ''[[VideoGame/RedFaction Red Faction 2]]'' have either Volcanic Veins or Tron Lines around their eyes and down their arms that pulse when they do something nano-related.
* The protagonist of ''VideoGame/OverlordII'' has bright blue veins on his dark blue skin.
* In ''Videogame/WorldOfWarcraft'', Deathwing has LITERAL volcanic veins, due to PowerIncontinence as a result of his corruption, he has cracks in his body through which LAVA seeps out, and if not for his armor holding him together, he wouldn't have lasted [[spoiler:as long he did]].
* In ''Videogame/MetalGearRisingRevengeance'', [[spoiler:Senator Armstrong]] gains these in the final boss battle of the game.
* Collector Drones in ''VideoGame/MassEffect2'' do this when Harbinger [[VillainOverride assumes direct control]].
* Revenants in ''VideoGame/MortalKombatX'' have volcanic veins, especially on their torsos, upper arms, and around their eyes. It's particularly prominent on Kitana and Jax. This is in contrast to the previous game, where revenants had cracked grey skin to reveal their undead status.

[[folder:Web Comics]]
* Ava in ''Webcomic/AvasDemon'' has had Volcanic Veins ever since [[spoiler:the pact with Wrathia.]]
* This is one of the manifestations of a [[Webcomic/{{Crankrats}} Crankrat's power.]]
* Willow of ''Webcomic/{{Earthsong}}'' gets deep purple veins around her manifest stone and then up her arms when she develops and then overuses her soulstone power [[spoiler:of manipulating soulstones]].


[[folder:Web Original]]
* In ''Literature/{{Phaeton}}'' when Trayen energises, Kazuo absorbs rather than nullifies, Lalita absorbs water, Frost powers up and probably a few things that haven't been mentioned yet, this will happen.

[[folder:Western Animation]]
* In the latest episodes of ''WesternAnimation/CodeLyoko'', the [[GiantMook Kolossus]] sports quite literal Volcanic Veins since it has the appearance of a giant lava {{Golem}}. As expected, they cool down and the glow dissipates once it's finally killed.
* From ''WesternAnimation/{{Wakfu}}'', Rubilax the major Shushu also has glowing Volcanic Veins in his true, demonic giant form.
* In ''WesternAnimation/StarVsTheForcesOfEvil'', both [[TheDreaded Queen Eclipsa]] and [[spoiler: [[TheHighQueen Moon]]]] develop these from using black magic.
* [[BigBad Megatron]] from ''WesternAnimation/TransformersPrime'' briefly displays Volcanic Veins as a result of being corrupted by [[GreenRocks Dark Energon]] during his fight with [[TheHero Optimus Prime]].

[[folder:Real Life]]
* Certain medical tests involve injecting the patient with a mild radioactive isotope, which shows up something like this on radiation-sensitive cameras.
* There is a story out there about a drug dealer who tripped out at a rave and injected glow stick fluid into his veins. He had this effect for several minutes, and became the center of attention... [[RealityEnsues and then he dropped dead]].
* Modern genetic engineering allows to introduce some genes into plants, making them glow under certain conditions. In particular, there are pictures of tobacco plant which is glowing more or less uniformly except its leaves, where it looks surprisingly like this.
