Blood Manipulation

Characters from Vampire Knight can utilize their blood as weaponry.

Background

Blood Manipulation is the ability to influence and control blood in various ways, such as altering its composition, transforming it, using it offensively or defensively, enhancing the body, or affecting an organism at a fundamental level, including rewriting the genetic code of blood cells.

Also Called

• Hemokinesis
• Sanguine Control
• Blood Bending

Capabilities

• Manipulation of blood as a liquid: Functions similarly to liquid manipulation, allowing the user to shape blood, alter its density, or imbue it with unnatural properties, such as forming sharp weapons. It can also enable control over another’s bloodstream, potentially rupturing blood vessels from a distance.
• Manipulation of blood as a source of energy: Converts blood into energy, replenishing the user’s strength, often seen as a vampiric ability.
• Manipulation of blood as an information object: Grants the ability to extract knowledge from blood (such as a person's identity or health status) and alter it, potentially modifying genetic information and transforming a being into something entirely different.
• Blood Magic: Enhances the power of spells through the use of blood. A single drop may suffice for summoning rituals, cursing an enemy, or causing harm from a distance.

Possible Applications

• Blood-based attacks (e.g., forming projectiles or weapons)
• Healing through blood manipulation
• Enhancing physical abilities through blood alteration
• Controlling another’s bloodstream
• Extracting genetic information

Potential Types

• External Blood Manipulation: The ability to control blood that has left the body.
• Internal Blood Manipulation: The ability to manipulate blood while it remains inside the body.
• Blood Clotting Control: The ability to regulate clotting to prevent or induce hemorrhaging.
• Blood Weaponization: The creation of weapons and tools from blood.

Limitations

• May require the presence of blood to activate abilities.
• Excessive use can result in self-inflicted blood loss.
• Certain beings may have immunity to blood-based effects.
• Might be restricted by external factors, such as dehydration or iron deficiency.

Users

• Alucard (Hellsing): Vampires in Hellsing are able to use their blood to absorb beings, with Alucard himself using his blood to amass a large army of souls within his body, allowing repeatedly revive upon death.
