Vampire Logia: "Akuma no Mi: Jikū Kesseki" (Blood Shadow Fruit)

Type: Logia

Powers: This Logia grants the user complete control over blood, both their own and that of others. They can transform their body into blood, becoming intangible and highly mobile. This blood form allows for rapid movement through tight spaces, infiltration, and evasion of attacks. The user can manipulate the blood's viscosity, solidifying it into sharp projectiles or creating shields of varying density. They can also absorb blood to heal themselves or enhance their abilities, becoming stronger and faster with each absorption.

Weaknesses: While in blood form, the user is vulnerable to extreme temperatures (both extreme heat and extreme cold, which can cause the blood to coagulate or evaporate). Powerful attacks that can disrupt or destroy the blood itself, such as highly concentrated sea-stone based attacks or extremely powerful concussive forces, can also harm the user. Furthermore, the user's reliance on blood for sustenance and power makes them vulnerable to dehydration and blood loss from external sources. They are also susceptible to attacks that target the circulatory system directly.

Unique Abilities:

• Blood Mimicry: The user can perfectly mimic the appearance and texture of any blood type, allowing for infiltration and deception.
• Hemokinesis: The user can manipulate the blood of others, controlling its flow, clotting it, or even extracting it from a distance.
• Blood Constructs: The user can create complex constructs and weapons from solidified blood, ranging from simple blades to intricate shields and even temporary golems.
• Shadow Manipulation: The user can blend their blood form with shadows, becoming virtually invisible and capable of moving through shadows with incredible speed. This enhances their infiltration capabilities and allows for surprise attacks.
• Blood Drain: The user can drain the blood of their opponents, weakening them and simultaneously strengthening themselves. This ability has a limit based on the user's current blood volume and capacity.
• Blood Regeneration: The user's regenerative abilities are significantly enhanced, allowing for rapid healing from injuries. This regeneration is fueled by the blood they absorb.

Limitations:

• Blood Dependency: The user's powers are directly tied to the availability of blood. In environments lacking blood, their abilities are significantly weakened.
• Vulnerability to Seastone: Like all Devil Fruit users, the user is vulnerable to Seastone, which negates their powers.
• Mental Strain: Extensive use of the fruit's abilities can lead to mental and physical exhaustion.
• Ethical Considerations: The user's powers raise ethical concerns, particularly regarding the manipulation and absorption of other beings' blood.
