Alien Blood / Video Games

• Alien Breed: In the second generation games, the Breed are revealed to have green blood.
• Arknights
  • The Doctor's blood is very unusual, especially as they don't seem to correspond with any known race on Terra. It apparently glows blue-green when a certain chemical is applied to it, and it has powerful healing properties. In addition Warfarin, a vampire Operator, is normally able to control her Horror Hunger toward blood, but she has an almost uncontrollable urge to consume the Doctor's blood that necessitates she be kept separate from them.
  • The three Abyssal Hunter Operators (Skadi, Granii and Spectre) have extremely unusual biology and blood, as they are hybrids of Aegir humans and the Abyssals. Their blood has an unusually low amount of Originum particulate in it, which naturally occurs in every Terran race. In the Under Tides event, when Skadi bleeds, it triggers a massive attack by Abyssals who think that they smell their own blood being spilled. Being a Hive Mind, the blood scent makes the Abyssals instinctively think that Skadi is one of their own who is trapped in a human body and try to "free" her.
• Battle Axe: The lowest-level goblin enemies bleed orange. Because of the game's tendency to have everything explode into Ludicrous G Ibs for no reason (even if killed by a sword), when fighting large numbers of goblins you can paint a kaleidoscope of orange all over the place.
• Bendy and the Ink Machine is full of life forms who are made out of black ink. Whenever they bleed, they bleed, well... black ink.
• The Binding of Isaac: Rebirth:
  • The DLC bosses Rag Man and Rag Mega both bleed violet. No explanation is given, but it is the same color associated with psychic abilities in the game, and both bosses have at least one trait involving that color. (Homing shots and giant orbs/beams of light, respectively.)
  • Ghost enemies splatter in white ectoplasm when killed, instead of the regular blood that everything else turns in to upon death.
  • While Wrath has red blood, Super Wrath inexplicably bleeds grey. It's possible that his blood is meant to be filled with ash given his attack method.
  • Inverted by spiders; they have red blood, but spider blood in real life is pale blue.
• Bloodborne: Some creatures bleed grey or green. The Plain Doll bleeds white. And that's not counting the blood of an Eldritch Abomination that underpins the plot.
• Blood Omen: Legacy of Kain: You play a vampire whose health bar is a blood bar, so NPC blood is Colour-Coded for Your Convenience: Red blood restores your health, the blue blood of ghosts restores your mana, black blood lowers your health, and green blood poisons you.
• Breed: The titular aliens bleed blue or green.
• Brutal Orchestra: Everything in Purgatory bleeds "pigment," which comes in four different colors (red, blue, yellow, and purple).
• Combat Instinct: While the Gnork has red blood, the Hrumians have purple blood.
• Cookie Run: Kingdom: Cookies have strawberry jam as blood, but Schwarzwalder — aka Choco Werehound Brute — boasts that he has cherry blood. This becomes a plot point in the Holiday Express storyline. Ol' Jolly seems to have died with a pool of blood, but he would be bleeding cherry blood if he was dead. The "blood" in this case is a slice of melted berry ice cream cake.
• Cthulhu Saves the World: Discussed. Umi asks the blood types of her allies, and Cthulhu answers he's got ink for blood. Similarly, Paws, an alien resembling a cat, says he's got uranium for blood while Ember the demon dragon says to have acid for blood.
• Detroit: Become Human: Androids are powered by a fluid called Thirium, colloquially dubbed "blue blood" since that's essentially what it is.
• Devil May Cry:
  • Devil May Cry 2: Msira have blue blood while their Homromsira variant bleed a yellow magma-like substance. Gbusmsira and Jomothumsira go back to blue blood, which the Goat family demons share. Jokatgulm and Tateobesu both bleed purple, while Phantom and Furiataurus bleed magma like the Homromsira. The Infestants, Larvae and Noctperan bleed white, and finally Oranguerra bleeds green. Quite the rainbow of blood colors in this game.
  • Devil May Cry 3: Dante's Awakening actually has creatures "bleed" appropriate to what they are — sand, ichor, impact sparks, whatever.
  • Devil May Cry 4: Only half-humans bleed red, while organic demons have blue, green, or orange blood instead.
• Diablo III: When the angel Imperius is wounded in a cutscene his blood is white and glows, in keeping with angels being creatures of light rather than flesh and blood.
• Divinity: Original Sin II:
  • The Voidwoken, the game's primary villains, have cursed blood that appears dark and swimming with leeches when spilled. It also inflicts a Revive Kills Zombie effect on contact.
  • The Bleed Fire status causes the inflicted characters to bleed fire rather than blood.
  • Several Polymorph Skills allow the caster to transform their blood. Its main purpose is to gain an immunity to an element or two (while gaining vulnerability to another), but it also makes the caster bleed an elemental puddle rather than blood when hit. They are Flaming Skin (bleeds fire), Icy Skin (bleeds ice), Jellyfish Skin (bleeds electrified water) and Poisonous Skin (bleeds poison)
• Doom: The Cacodemons and Barons of Hell appear to leak blue and green fluids when they die, even though their blood spatter when hit while alive uses the same red color as seen for other creatures in the game. Word of God says this is because both do have red blood, but their innards are blue/green. However, it has been suggested that they simply didn't have a way to color-shift the red blood splatter sprites and did not want to waste space on differently-colored graphics. Some modern source ports have remedied this by allowing the blood color to be shifted for different enemies. Doom Eternal depicts both Cacodemons and Arachnotrons with blue blood.
• Dragon Age:
  • Dragon Age: Origins: Zig-Zagging Trope. Several people, including people who have firsthand experience against them, refer to darkspawn blood as being "black as sin"; however, all blood in the game is animated as a bright red. At one point, the PC can explain that while the idea of the blood being black is a common misconception, it has various inhuman properties: most notably and well known is how toxic it is, with exposure into an open wound being almost universally fatal to anyone but a Grey Warden, and likely related to this is the less obvious fact that it burns the skin on contact.
  • Dragon Age: Inquisition: In the DLC "The Descent", it emerges that lyrium itself is the distinctly alien, multi-purpose "blood" of massive subterranean creatures called Titans. Amusingly, magic involving *normal* blood is shunned and reviled by most of society. One wonders what the reaction will be to this news spreading.
• Dwarf Fortress: There are different colors of blood based on the creature that bled it. Troll blood is a bright cyan, some sea creatures bleed dark blue (based on their real life counterparts), fire imps have gray goo in the place of blood, and invertebrates have white "ichor". Like all things Dwarf Fortress, this can be modded to taste. There is, for instance, a Homestuck troll mod covering the entire hemospectrum.
• Elden Ring: Albinaurics bleed silvery-white.
• Fallout: New Vegas: The Ghost People of the Sierra Madre bleed green, but this may not be blood since their insides apparently have a slushy like consistency, so what leaks out of them is the liquid part of the slushy.
• Far Cry 3: Blood Dragon: Cyborgs of all varieties, including the player character Rex "Power" Colt, all have blue blood. Poked fun at in a late-game cutscene where the Big Bad tries to tell him that they both have the same blue blood, to which Rex replies that, no, his blood is red, white, AND blue.
• Hades: As they did in Classical Mythology, the gods bleed golden ichor instead of red blood. The exception to this is the protagonist, Zagreus, whose red, humanlike "weak blood" is occasionally brought up as a subject of derision.
• Half-Life: The aliens (and the cockroaches, which is Truth in Television) bleed light yellow.
• Halo: Elites and Jackals have purple blood, Hunters orange, Brutes and Prophets red, Grunts luminous blue, and Drones whitish green. The Flood are a different story: they don't bleed just green blood; Infection Forms will liquefy the internal organs of the host, so in reality they're spilling out their entrails in liquid form. Unless the "Grunt Birthday Party" skull is enabled, in which case headshots will cause the Grunts to bleed confetti and cheering.
• Most enemies in Hands of Necromancy averts the trope by bleeding red (or don't bleed at all, for ghosts and rock monsters) but then there's the Hell Burners, Satanic-looking Big Red Devil enemies who bleeds dark turquoise. There's no explanation to why it does so.
• Hollow Knight's enemies flash and emit liquid of a certain color when hit to indicate their state or what they are made of:
  • The ordinary color for uninfected bugs, beings, and ghosts is white.
  • Infected bugs flash and bleed orange blood.
  • Beings made out of void will spurt a black substance known as void.
  • Masks stained with Lifeblood will cause the Knight to bleed blue blood.
• Hyper Light Drifter: The Player Character's blood is a shimmering magenta fluid that evaporates quickly. Occasionally, fits of a mysterious illness cause them to cough it onto the ground.
• Jet Force Gemini: The ant-like enemies bleed green blood when you shoot them; and a special "cheat code" makes them bleed rainbow colored blood.
• The Legend of Zelda:
  • The Legend of Zelda: Ocarina of Time: Ganondorf originally coughed up regular red blood upon being defeated, but later versions of the game had him coughing up green blood instead.
  • The Legend of Zelda: Twilight Princess: Morpheel produces purplish blood when its eye is attacked. Also, Dark Beast Ganon drips glowing white blood from his old abdominal wound.
  • The Legend of Zelda: Breath of the Wild: The Blight Ganons spew geysers of reddish-purple liquid Malice when they are defeated.
• Marathon: Most Pfhor (fighters, troopers, enforcers and minor hunters), ticks, lookers and simulacra have fluorescent yellow blood, major hunters and Mothers of All Hunters bluish-gray, F'lickta mixed green and red, hulks blue, S'pht green, and wasps and tank-cyborgs purple.
• Mary Skelter: Nightmares: Marchens bleed glowing pink blood. Just to show that this isn't censorship: Jack, a human, bleeds the usual red blood.
• Mass Effect:
  • A common taunt directed at humans who express conciliatory philosophy toward the varied races of the galaxy is "Do you remember what color your blood is?" Just for fun, stand up to the leader of the isolationist "Earth First (we can exploit the other planets later)" Terra-Firma party. Strangely, several non-council races have the same red coloured blood as humans, namely batarians, vorcha, and quarians. Others colours include blue turian blood, orange krogan blood, green salarian blood, blue-purple asari blood, light green rachni blood, and yellow Collector blood. A keeper shot by Saren can be seen bleeding black fluid, which is quite possibly artificial, given that they have been heavily bio engineered. Geth are fully synthetic, but "bleed" white fluid when killed.
  • Thorian creepers don't bleed per se, but they do generate splatters of brownish-green material when they die.
  • Blood colors in ME also qualify for Shown Their Work credit, as species with alternate colors of blood have skin and/or mucous membrane coloration to match (asari, who bleed purple, have various tones of blue or purple skin as well as lightly blue-tinged sclerae; krogan, who bleed orange, can exhibit red or yellow eyes; Garrus and several other light-colored turians have a faint purplish cast to their facial features).
  • The krogan have another odd variant on blood, as well. They don't actually have a nervous system made up of nerve cells; rather, they have a second circulatory system consisting of an electrically conducive fluid that runs through their body. As a result, krogan cannot be paralyzed. This physical trait is shared by all other species on Tuchanka, the krogan's homeworld.
  • Shown in practice in Mass Effect 2, when Garrus gets shot during his recruit mission, and bleeds blue all over the floor, and is later seen with purple scar-tissue over third of his face, mostly covered with cybernetics.
  • Mass Effect: Andromeda: The angara bleed a sort of blue, while the kett have bright green.
• Metal Gear:
  • Metal Gear Solid 4: Guns of the Patriots: The Super-Soldier Raiden has white nanomachine-based blood, the potential symbolism of which is not lost to Vamp.
  • Metal Gear Rising: Revengeance: Cyborgs use a more advanced artificial blood that is red (except in the Japanese version, where it is still white due to censorship) that does not require the frequent dialysis that the original white blood did.
• Monster Hunter:
  • The Neopterons are not aliens, but rather oversized insect-like monsters (the smallest is at least as big as the hunter's torso). Just like a real world insect, their blood is green, especially noticeable with Neopteron Large Monsters.
  • Monster Hunter 4 introduces the Gore Magala, an enigmatic new monster with purple blood, that is the source of a deadly virus that spreads to humans and monsters. While there is no physical change for humans that are infected, infected monsters start spilling purple blood when hit with attacks as well. When a Neopteron gets frenzied, their blood is ALSO purple despite a healthy Neopteron having green blood initially, showing just how much the virus can corrupt a monster's physiology.
• Mortal Kombat: Reptile and Khameleon have green blood (Sheeva had green blood in MK3 and its updated versions, but her blood from MK: Armageddon onwards is red) - Reptile's blood was red in the first two games, but became green from Ultimate Mortal Kombat 3 onwards (except in MK4, curiously). Cyborgs have black oil instead of blood, Blaze has molten lava, D'Vorah has blue fluid, Noob Saibot has black... wraith juice and Cyber Sub-Zero bleeds a light blue combination of oil and antifreeze. Some guest fighters also have different colored blood to match their original franchise: Predator has bright green blood while the Xenomorph has yellowish-green blood (which, due to Gameplay and Story Segregation, is only acidic for certian moves). Spawn also has green blood and Robocop has the same black blood as other androids.
• Mutant Football League: Aliens bleed neon green when hit, and explode in a shower of acidic blood when killed. Nearby opponents will be either killed, benched due to low health, or softened up for a deathblow in the next few downs. This means that trying to cripple the all-alien Galaxy Chaos team by killing their stars will deplete your own defense significantly
• Nanobreaker had various robot/cyborg enemies, and a menu where you could decide what of wide range of colors of "blood" they would bleed as you viciously dispatch them with your shapeshifting sword. For great humor, select the "random" option, and turn your battlefield into a particularly colorful impressionistic painting!
• Nitrome Must Die: Enemies bleed a variety of colors, usually depending on what color the enemy's design is. While red enemies do bleed red, it still doesn't resemble normal blood.
• Penny Arcade Adventures: Clowns bleed rainbow colors.
• Perfect Dark: The Maians have green blood. The Skedar, meanwhile, have red blood.
• Ratchet & Clank: It's rare, but some enemies spew green slime when killed, such as the frog/toad enemies.
• Resident Evil:
  • Resident Evil 3: Nemesis has the Nemesis monster bleed red when shot at, but when he gets knocked out after taking enough damage, his pool of blood is purple.
  • Resident Evil Gaiden: The ending zooms in to show Leon bleeding green blood, implying he's actually the B.O.W. Parasite in disguise.
• The Riftbreaker alien enemies have a variety of blood colors. This includes green, red, purple, blue or yellow blood. Some even bleed mud or magma.
• SAR: Search and Rescue have mutated ex-humans, revived by an alien virus as a recurring enemy. You realize they're no longer human when you shoot at them, revealing purple or blue blood.
• SaGa Frontier: Mystics have blue blood, Half-mystic protagonist Asellus has purple.
• Skullgirls: If you go through the character profiles, you may see a few unusual blood types. Painwheel has SG (Skull Girl), Squigly has "Embalmed" (undead), and Big Band has B♭ (oil mixture, being a cyborg). Eliza has "Any".
• Shadow the Hedgehog: The Black Arms have green blood. Also a case of Black Blood, as it was going to be red before the developers had to change it to avoid a T rating.
• Splatoon: Inklings and Octolings could be considered a somewhat non-standard version of this, as they're literally made of ink, which presumably fulfills the same functions that blood does, right down to splattering everywhere when they're killed.
• Star Ocean: A major plot point is that Fellpool have copper-based blood -= but everyone from that planet has properly pink skin (or tan, in the case of the Highlanders). The only outward difference from Terrans is their tails and sometimes fangs.
• Subnautica: Marine wildlife of 4546B will bleed clouds of pale yellow into the water when injured or killed.
• Sunset Overdrive: All of the OD bleed bright orange blood, likely from all the Overcharge in their systems, since it's orange and it's what made them into OD.
• Teraburst: The common alien foot-soldiers bleed purple. A lot, too, because of every death ending in Ludicrous Gibs.
• Unreal series:
  • Unreal: The Mercenaries have green blood. Averted with every other alien race, however, which all bleed the same red blood as the player character.
  • Unreal Tournament: The Necris bleed a black substance called "nanoblack" rather than regular red blood.
• Warcraft:
  • Orcs have very dark blood, which is why many of the more or less racist humans call them blackbloods. Similarly, the blue-skinned draenei have blue blood. That, and their unguligrade appearance has caused a few fans to compare them to the Warhammer 40,000 Tau (although people are even more likely to compare draenei to Protoss). Demon blood seem to be fluorescent green (which is pretty much the trademark colour of fel energy) that more than one NPC has compared to "liquid rot". Sufficiently powerful demons have lava instead of blood. Most undead, including the playable Forsaken have green embalming fluid instead of blood.
  • World of Warcraft: Void elves have purple blood.
• XCOM: Enemy Unknown: All aliens bleed orange-yellow blood, which you can often see when it sprays on the screen during the autopsies or when it pools on the ground after they die. This carries over to ADVENT troops in XCOM 2, which is the first sign that they're not entirely human.
• Yume Nikki: Conspicuously averted. When Madotsuki stabs a Dream Land creature, it doesn't matter what it is: be it a bird girl, a giant foot-Martian who cries green tears, a poop monster, a horrified face on the wall, they will always bleed red blood and let out a human-like scream.
