History Main / VolcanicVeins

* Members of the Vandenreich in ''Manga/{{Bleach}}'' sometimes show these when using Blut Vene to defend against attacks.

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]].

* 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.

* ''Film/TheHobbit'': In the [[Film/TheHobbitTheDesolationOfSmaug last tw]][[Film/TheHobbitTheBattleOfTheFiveArmies o films]], the dragon Smaug has this effect. The gaps between the scales on his throat and belly glow red when he's about to breathe flame.

* A lot of the {{Kaiju}} from ''Film/PacificRim'' posses this, such as [[ExactlyWhatItSaysOnTheTin Knife]][[WarmUpBoss head]] and [[FatBastard Leather]][[{{EMP}} back.]]

* 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]].

* ''ComicBook/{{Batman}}: Bane is sometimes depicted as having glowing green pulsing veins when he injects the [[SuperSerum Venom]] that gives him his strength.
* ''ComicBook/WonderWoman2011'': The version of Hephaestus in the New 52--later revealed to be a fake and part of a set of implanted memories in ''ComicBook/WonderWomanRebirth''--has cracked looking skin with glowing red veins on his hands, which fades into pink skin up his forearms.

* ComicBook/{{Bane}} is sometimes depicted as having glowing green pulsing veins when he injects the venom that gives him his strength.

* The season two premiere of ''Series/TheGifted'' sees Reed Strucker exhibiting these. [[spoiler: He's a mutant whose father chemically suppressed his powers. Looks like it's wearing off.]]
* ''Buffy the Vampire Slayer'': Anyanka (season 3) and Dark Willow (season 6); others?

** 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.

* 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.

[[folder:Web Comics]]

* This is one of the manifestations of a [[Webcomic/{{Crankrats}} Crankrat's power.]]

* ''WesternAnimation/StevenUniverse'': The [[spoiler: five-Gem [[FusionDance fusion]] [[MagmaMan Obsidian]]]] has red glowing lines all throughout her body and hair.

* VideoGame/XCOM2's Templar faction all have these in purple, likely a result of their advanced psychic powers.

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

* 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.

* Franchise/{{Godzilla}} sports this in his Burning Godzilla forms in ''Film/GodzillaVsDestoroyah'' and ''Film/GodzillaKingOfTheMonstasers2019''.

* Franchise/DCExtendedUniverse: Happens to the skin around Superman's eyes whenever he uses his EyesBeams, particularly in ''Film/ManOfSteel''. The Sun gives him a HealingFactor so it doesn't last on his face.

** There is a species of orchid, ''[[https://en.wikipedia.org/wiki/Macodes_petola macodes peteola]]'', that can look like its veins are glowing ''Franchise/{{TRON}}''-style ([[https://bit.ly/3jDBu6z see?]]). Yes, it's naturally-occurring, if you're wondering.

* 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]].

* ''TabletopGame/Warhammer40000'': Avatar of Khaine manifests as a towering iron statue covered in a network of glowing cracks, symbolizing the immense power of the war god barely held within a physical shell.

* 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]].
