* The ''VideoGame/MetalSlug'' series has a zombie apocalypse stage in some of its iterations. When you get hit by a zombie you don't die immediately, but you become a lumbering zombie yourself. Your gun as a zombie is crap but your grenades become a stream of blood that your character vomits in an arc that sweeps over half of the screen, and it's also one of the most powerful attacks in the series.

* ''TabletopGame/TheUnofficialHollowKnightRPG'': The Bloodboil spell causes blood-soaked weapons to burst into flame, making those weapons deal bonus fire damage. It can also be cast directly on a creature to damage them.

* ''Literature/MadgieWhatDidYouDo'': [[http://akaichounokoe.deviantart.com/art/Shattered-Glass-273936881 Toki's]] blood is apparently toxic, considering that it can turn you crystal when it ends up someone that isn't her sister's (or baby's) bloodstream. This is a variant in that, while toxic, it has to get ''into'' a person for the effect to work. At the same, it also does causes flowers to sprout, as demonstrated in one story.

* In ''[[VideoGame/{{Turok}} Turok 2]]'' there were zombie enemies that could throw blood at you. If you went to the options screen and turned the blood off, this section became a lot easier.

* ''Literature/MadgieWhatDidYouDo'': [[http://akaichounokoe.deviantart.com/art/Shattered-Glass-273936881 Toki's]] blood is apparently toxic, considering that it can turn you crystal when it ends up someone that isn't her sister's (or baby's) bloodstream. This is a variant in that, while toxic, it has to get ''into'' a person for the effect to work. At the same, it also does this to flowers, as demonstrated in one story.

Destroying one will cause a Witch to lose a lot of her power, greatly weakening her.

* TheFairFolk in ''Literature/{{Moonflowers}}'' have corrosive blood--it burns humans, and can eat through the metal of a car enough to require extensive repairs. It also goes the other way: HUMAN blood will burn fairies on contact, if the human's recently eaten rock-salt.

** Both types of vampire can use various different attacks with blood. The Stone Mask vampires can freeze blood on contact and [[EyeBeams fire high-pressure streams of blood out of their eyes]]. The [[OurVampiresAreDifferent Pillar Man]] Esidisi can heat his blood to 500 degrees Celsius and shoot it out of his veins.

* Baruragaru from ''VideoGame/MonsterHunter Frontier'' is a Leviathan that weaponizes the blood it sucks from Bird Wyverns such as Velocidrome, Gendrome and Iodrome into various attacks. Such as an attribute-lowering attack with Velocidrome blood, paralyzing strikes with Gendrome blood and poisonous mists with the Iodrome's blood. It can also drain the hunter of blood and use it for attacks, too.

* ''Manga/BloodBlockadeBattlefront:'' All of the members of Libra (barring [[NonActionGuy Leo]] and [[OurWerewolvesAreDifferent Chain]]) are of weaponizing their blood in a variety of ways.

* ''Manga/BloodBlockadeBattlefront:'' All of the members of Libra (barring [[NonActionGuy Leo]]) are capable of manifesting weapons made of their own blood.

*** Some [[MagicKnight Librarians]] of the [[OurVampiresAreDifferent Blood Angels]] are able to boil the blood in their enemy's veins and cause it to explosively burst from their pores. In-game this is represented by the Sanguinary Discipline PsychicPower [[ExactlyWhatItSaysOnTheTin Blood Boil]] that could instantly kill the target[[note]]in 7th Edition[[/note]] or cause multiple [[UnblockableAttack mortal wounds]][[note]]in 8th Edition[[/note]].

* ''VideoGame/DevilMayCry5'' has [[NiceHat Dr. Faust]], which gives Dante some control over Red Orbs, AKA crystallized demon blood, which he can use to both deal damage to enemies by throwing the orbs at demons, or make enemies he attacks drop more orbs when hit. Red orbs are also used to buy new abilities and items in the shop, which makes it double as AbnormalAmmo and MoneyMauling.

** This is one of 0's attacks in ''VideoGame/KirbysDreamLand3''. Yes, you read that correctly. The TrueFinalBoss of a K-A rated SNES game cuts itself so its blood will attack Kirby... and also ''rips out its own bloody iris'' as a last-ditch attempt to kill Kirby.
** And then cue Zero Two in ''VideoGame/Kirby64TheCrystalShards''. He friggin' cries blood, to be expected since he's more-or-less a reincarnation of Zero; moreover, the tips of his wings are soaked with the stuff, and may shoot blood at Kirby, too. (Even though it looks more like green gas; this could just be a form of censorship.) It also splatters about whenever you hit Zero-Two in its eye, and flies everywhere once the normal Zero is defeated. However, due to the graphics it can be mistaken for red energy or explosions.

* ''Film/TokyoGorePolice''. It's the plot of the entire movie.

* The [[Whatevermancy Sanguimancer]] of ''VideoGame/SaltAndSacrifice'', as his name suggests, can conjure blood in order to attack the player. Fortunately, he lacks the ability to control the player's blood.

* In ''Manga/{{Basilisk}}'', [[FemmeFatale Akeginu]] of the Iga Tsubagakure group not only is extremely seductive as well as [[KnifeNut deadly with her trusty]] ''[[KnifeNut tanto]]'' [[KnifeNut dagger]], but she can also control her own blood, secreting it out of her pores to blind or tag her opponents or create a sort-of mist as she mixes it with the air in her surroundings.

* When Angelus gets loose in ''Series/{{Angel}}'', Wes and Faith take him out by using Faith's blood against him. They know Angelus won't be able to resist trying to turn a Slayer, so they inject Faith with a dangerous hallucinogen just before the fight, then let him win. It's a big risk, but it works -- Angelus is unconscious long enough for Willow to restore his soul.

* Testament from ''VideoGame/GuiltyGear'' has a [[SinisterScythe Scythe]] made out of his own blood. His sprite shows that there's a hole in his hand that he draws the blood out of. One of his special moves involves cutting himself and forming a web out of the blood spray, to trap his opponent.

* In ''Fanfic/MakeAWish'', Harry's incredibly poisonous blood (it contains Basilisk venom) protects him several times. The first, when [[spoiler:he is attacked by werewolf Fenrir Greyback, poisoning Fenrir while Harry completes the work with a silver knife]]. The second, when [[spoiler:Lord Dracula gives him blood to turn him into a vampire (the only way he won't become a werewolf) but instead stabilizes things and turns Harry into some sort of hybrid]]. The third, when [[spoiler:he gets bitten by several Australian poisonous spiders, who [[IncrediblyLamePun bite it]] when Harry's blood enters their mouths.]]

* '''Poison Blood''': The blood itself is poisonous, and either direct contact or indirect exposure to it is enough to kill.
* '''Corrosive Blood''': The chemical nature of the blood is such that it eats through metal and flesh--[[RequiredSecondaryPowers presumably the owner has sufficiently resistant veins and tissue]].
* '''Blood Weapons''': The blood can "[[BodyToJewel crystallize]]" or [[ShapeshifterWeapon solidify into a weapon]]. Usually, this is helped by most fictional characters having [[OverdrawnAtTheBloodBank excessive amounts of blood in their bodies]]. May overlap with ExtraOreDinary if they're manipulating the [[BloodIron iron in the blood]], which may let them turn blood into sharp blades.
** '''Prehensile Blood''': An extension of the above and similar to PrehensileHair, only this blood is a [[CombatTentacles tentacle horror]].
* '''Projectile Blood''': Sprays the blood or shoots it in globs, in a similar phenomenon to MakingASplash.
* '''Blood Boost''': The character gains increased abilities as he bleeds. This is almost always due to [[BloodMagic magical power inherent in spilling blood]] (only [[CastFromHitPoints focused on the caster's own body]] rather than a victim), but it occasionally has some other explanation.
* '''Blood Horrors''': The blood can [[MookMaker spawn]] [[FertileBlood minor minions]] to do their master's bidding, or even [[SelfDuplication clones of said user]]. Compare this one with AsteroidsMonster.
* '''Boiling Blood''': Instead of using his blood, the character can boil [[MyBloodRunsHot his own]] or his enemies' blood in their veins, leading to a ''[[CruelAndUnusualDeath very messy]]'' death.

* '''Blood Weapons''': The blood can "[[BodyToJewel crystallize]]" or [[ShapeshifterWeapon solidify into a weapon]]. Usually, this is helped by most fictional characters having [[OverdrawnAtTheBloodBank excessive amounts of blood in their bodies]]. May overlap with ExtraOreDinary if they're manipulating the iron in the blood, which may let them turn blood into sharp blades.

* ''VideoGame/{{Touhou}}'':
