Alien Blood / Live-Action Films

aka: Film

• In Alice in Wonderland (2010) the Jabberwocky's blood is purple.
• Alien:
  • The Xenomorphs have yellowy-green, highly acidic blood that can burn through steel. In the later movies, the blood is green instead, possibly as a result of morphing with human DNA. A reasonable theory, however, would be that the acid doesn't actually have the same purpose as blood — it's more of a defense mechanism that makes its victims reluctant to kill it.
  • The androids have milky white fluid inside them instead of blood.
  • Ripley 8 in Alien: Resurrection is a Half-Human Hybrid due to a cloning mishap. Her blood is a human red but it's also corrosive, though to a much lesser extent than a purebred Xenomorph.
  • The Neomorphs in Alien: Covenant have yellow blood. It's not acidic, though.
  • And the Engineers' blood in Prometheus appears to be a light green color.
• Many viewers mistakenly assume that the Penguin in Batman Returns has greenish-black blood, since he's seen spitting up a substance of that color in his death scene. However, we also see him bleeding red blood from his bat bite wounds, and according to the crew members, it's supposed to be bile, and it can be seen trickling out of his mouth at multiple points in the film, it just intensified after he fell into a pool of toxic waste.
• Blade II: Caused by Executive Meddling from the censors. For some reason they needed to have some of the characters such as the (non-Reaper) vampire Damaskinos bleed green to get an R rating, even if there's gallons upon gallons of red-coloured gore anyway.
• In 1978's The Blue Stigma aka Blue Christmas aka Blood Type: Blue, a huge spike in UFO sightings coincides with the people involved suddenly having their blood turn completely blue and their emotions based in anger seemingly wiped away. It is some kind of invasion? Does it have something to do with a music band's strange predictions of an upcoming apocalyptic event where Nazism would rise from the ashes and sweep the world? No one knows, but that doesn't stop the world's governments from making internment camps and pulling a Final Solution in the end.
• Critters: The Crites have green blood.
• The Strangers from Dark City (1998) melt into goo or turn red and dissolve into flakes when they die; the dead human bodies they use as vessels have black blood.
• The Dark Crystal: The death of All-Maudra Mayrin seems to indicate Gelfling blood is pink. However, all of the comics depict their blood as deep red like that of humans.
• In Demon Knight, the Collector and his minions' blood is green.
• In The Devil's Rain, the members of the satanic cult bleed green or brown blood after they've surrendered their souls to Satan.
• Averted in District 9, where the Insectoid Aliens bleed a scarlet red. Possibly done to show that despite their appearance, they are not monstrous at all. Zigzagged with Wikus, who at one point has a nosebleed of a black fluid and vomits up black goo, but still bleeds red.
• Buckets of black and green Deadite blood get thrown around in the Evil Dead movies.
• The Eye Creatures: The eponymous Eye Creatures have very thick, blackish brownish blood. It looks very sickening.
• The Fifth Element: Diva Plavalaguna, the alien opera singer, has royal blue blood.
• Flash Gordon (1980):
  • Ming the Merciless has dark green blood.
  • The prince Ming stabs in the first court scene has blueish-purple blood.
  • When Klytus, Ming's Dragon, gets Impaled with Extreme Prejudice on a bunch of spikes, his entire body melts into black fluid.
  • General Kala's blood is also black, although she doesn't melt.
  • The Arborian who dies of the Hand in the Hole trope has pale green goo on his stung arm, but it's unclear if it's meant to be his blood or the creature's venom.
• Fortress (1992): The cyborgs that appear in the film, such as the Strike Clones, bleed a blue liquid.
• Freddy's Dead: The Final Nightmare: Freddy bleeds green when he slices his fingers off.
• Not quite aliens, but one of the first hints that the employees of the Titty Twister in From Dusk Till Dawn aren't human is a close-up of a knife which was just used to stab one of them. Instead of blood, it's covered in a translucent goo.
• The Gamera series features numerous examples:
  • Gamera himself has blood that ranges in colour from bright green to somewhere between bluish-green and teal.
  • Barugon's flesh and blood are both purple.
  • In Gamera vs. Gyaos, Gyaos has very pale purple blood that he sheds in great quantities after Gamera bites him in the neck during the final battle. The Space Gyaos introduced in Gamera vs. Guiron, much like Barugon, has purple flesh and blood.
• Gods of Egypt: Gods have liquid gold in their veins instead of blood.
• Godzilla:
  • Godzilla vs. Mechagodzilla: The Simians' blood is a grayish-green color.
  • Strangely, the Heisei incarnation of Godzilla bleeds green blood in The Return of Godzilla and Godzilla vs. Biollante, but his blood color was changed to red afterwards.
  • Godzilla vs. Biollante: Biollante has green blood, possibly due to her chlorophyll.
  • Godzilla and Mothra: The Battle for Earth: When Godzilla digs into Battra's flesh, he starts bleeding mustard-yellow blood all over him.
  • Godzilla vs. Destoroyah: Destoroyah has lime green or yellow blood. He spits or bleeds huge amounts of it in the later phases of the final battle. As a side effect of his meltdown, Godzilla's blood changes colour, ranging from red to orange to white in the latter stages of the final battle.
  • MonsterVerse: There's quite a few examples.
    • Godzilla (2014): The MUTOs bleed a thick, dark-looking blood, described in the novelization as being like sticky ichor.
    • Godzilla: King of the Monsters (2019): A couple cases. When Mothra stabs Rodan with her stinger, magma can be seen oozing out of his sternum, and special features confirm that Rodan has literal magma for blood as one of the physical adaptations that allow him to survive while sleeping inside an active volcano. Ghidorah, who unlike the other Titans is an actual alien, bleeds black blood, which the novelization describes as similar to oil.
    • Godzilla vs. Kong: The Warbats and skullcrawler have bright green blood.
• The Tao Tie from The Great Wall bleed green blood, befitting their emerald-jade appearance.
• From Green Lantern (2011) when a freaked-out Hal is trying to help a dying Abin Sur:
  Hal: Hey-hey-hey, listen, we're gonna get you to a hospital, okay? Okay? One th-th-that carries...purple blood.
• The aliens from The Green Slime: killing them is a bad idea because the puddles of light green blood will eventually regenerate into numerous more creatures.
• Gremlins (1984): The Gremlins bleed (often copious amounts of) green goo, whereas the Mogwai bleed red.
• Halloween: The Curse of Michael Myers: Michael bleeds yellow-green blood while Tommy beats him with a pipe.
• Hellboy:
  • The blood of Nazi cyborg ninja Karl Ruprect Kroenen from Hellboy (2004), as a result of his great age and grotesque mechanization, has long since dried out, leaving his veins filled with an inert powder as fine as dust. Also in the Hellboy movies (and animated movies, but not the comics), Abe Sapien has blue blood.
  • In Hellboy II: The Golden Army, the elven royalty has greyish yellow blood.
• The Hollow Child: The Hollow Ones it turns out have black blood, as one more sign they aren't really human.
• Independence Day: The alien pilot Grey kills in the first film is bleeding bluish-purple Blood from the Mouth.
  • Independence Day: Resurgence: In the sequel however, an injured alien that gets decapitated bleeds green, and the Queen likewise bleeds green slime.
• Downplayed in It (2017) and It: Chapter Two. IT's blood appears to be standard human blood, but what makes it weird is that it floats in mid-air rather than falling.
• In Disney's John Carter, Martians have blue blood. Despite all references to their blood in the books indicating that it was red.
• In Leprechaun 4: In Space, the Leprechaun goes into outer space and teams up with an alien princess. The princess looks just like a sexy blonde human woman (think Anna Nicole Smith with a very upper-class American accent); but then the human characters happen upon some samples of her blood...and they're emerald-green!
• Marvel Cinematic Universe:
  • Zehobereians like Gamora bleed green blood. In Avengers: Infinity War, when Thanos throws Gamora to her death in Vormir, there is a shot of her body with greenish blood around her head. This is contrasted when Natasha Romanoff suffers the same fate in Avengers: Endgame, except this time the blood is the very human red.
  • Used as a Bait-and-Switch in Captain Marvel (2019). The titular character is seen with blue blood in the opening scene, suggesting that she is an alien. The blood actually belongs to someone else, as Carol Danvers is a human and does have red blood.
• Whenever aliens are blown up in the Men in Black films we see strangely-colored fluids. Mikey's blood is bright blue. Jack Jeebs' is green.
• The Moorwen from Outlander has bright green blood.
• The Kaiju from Pacific Rim bleed blue when stabbed, slashed, gouged, plasma blasted, or otherwise maimed. Which happens a lot. Too bad the blood's toxic as all hell, though.
• The Tall Man in Phantasm gets his hand caught in a door at one point, and the boy cuts off his fingers with a blade. They bleed yellow; the director noted on the commentary that most test audiences were shocked at the unusual color.
• The flying monsters from Pitch Black have bluish-gray blood.
• The Predators from the films of the same name have fluorescent yellow/green blood that glows in the dark. As Schwarzenegger famously says in the first film:
  Dutch: If it bleeds, we can kill it.
• Poultrygeist: Night of the Chicken Dead: The chicken zombies have green blood.
• Skyline: The aliens bleed dark purple blood.
• One of the princes in Stardust has literal Blue Blood. Unknown if it's just because he's royalty, or if all inhabitants of the magical world have such blood, since nobody else in the movie is seen bleeding. Word of God states the decision for the color was made to avoid an "R" rating, with the added benefit of being a visual gag for the character.
• In Star Trek VI: The Undiscovered Country, Klingon blood is shown to be Pepto-Bismol pink. Likely done to avoid an R-rating as it ends up being splattered all along the walls of the ship. Also in the movie, there's an inversion where an apparent Klingon's regular red blood leads to the revelation that it's actually a human in a Rubber Forehead disguise. In the original theatrical edit of the movie, the unmasking scene was cut, making the scene seem like a bizarre oversight.
• In The Thing (1982), blood samples are taken from all the characters and exposed to heat to test which one is the shapeshifting alien. The alien blood, it turns out, is capable of leaping around the room as an independent organism. The character who proposed and carried out the test did it because he figured that the blood might well do that, as severed pieces had previously been observed operating independently.
• Most of the Graboid blood seen in the Tremors films is an orangish-red color, just different enough from the maroon-red of human blood to avert an R rating.
• In The Watch (2012), the aliens' blood is a green goo which (according to Bob) has the feel and texture of human cum.
• In The Wesley's Mysterious File, Fong Tin-Ai is a Human Alien who looks like an average Asian woman (played by Rosamund Kwan)... but bleeds blue.
• In The Witches (1990), most of the witches' blood is green when they are killed as mice, although some red blood is seen on the knives and cleavers the hotel staff use to kill them.
• In The World's End, the alien robot replacements for the townspeople all have blue ink-like "blood".
• Deadpool 2: If you doubted Shatterstar is telling the truth when he says he is an alien, we get confirmation once he unfortunately skydives into the blades of a helicopter, resulting in green blood splattering everywhere.
• Xtro: Sam's quadruped alien form appears to have orange and thick, almost gelatinous blood, most evident when he is accidentally hit by the couple's car, and the driver examines his wound. His second alien form has black blood.
• In Yamato Takeru, the Yamata no Orochi has lime-green blood.
