BNHA Quirks/Some Prompts

Quirk: Demonic blood

Demonic blood:

The user has demonic blood that they can control and bend at will to use to attack/defend. Their blood will also  burn  any target that it physically touches  but only if the user wills it too, otherwise their blood's abilities won't activate. Moreover, the  blood can: 

1) Make either clones or creatures from their blood that follow orders and share consciousness with them, allowing the user to receive information from wherever the blood creations are located.

2) Can be hardened for both protective and offensive purposes becoming exponentially stronger than reinforced steel. Due to its demonic nature, it is extremely resistant to high temperatures (can easily withstand Dabi's cremation flames) but is susceptible to cold temperatures and attacks that carry a tremendous amount of force (it can effortlessly tank many blows from  Katsuki's Howitzer Impact but will crumble after a few strikes from All Might's charged punches).

3) Burn targets that have been injured from the inside out by  igniting the traces of demonic  blood  that entered their  bodies.  This is called Blood Blaze and it  can cause massive internal damage which may lead to death  depending on the amount of demonic blood inside the target's body. The more wounds they receive from the user's demonic blood, the more damage they can suffer. The burns progression can be limited to the areas that have been injured but if a sufficient amount of demonic blood is forced into their bodies, they can be fully engulfed in hellish flames. The user can also control how long they 'cook' their targets as they can control the blood's combustion at will.

4) Can slowly weaken injured targets as the buildup of demonic blood will force the target's body to fight against the traces of the user's blood, causing them to burn away their own  vitality-  Vitality Burn.

5) Gives the user demonic attributes such as super regeneration, enhanced senses, demonic strength, speed, agility, and stamina.

As such, the user can rapidly replicate their blood to use and replenish in a fight. However, the user can only use their own blood at any moment. Meaning that they can become anemic if the battle lasts too long and if their blood is being constantly destroyed.

Demonic blood allows the user the power to fight alone or in a team. It works best when there are multiple targets involved as the blood burning effects can cause maximum pandemonium and massive damage in a group. It also has synergy with other demon-like quirks especially Demonification.

Drawbacks: anemia, mental confusion, lethargy, headache,  muscle weakness, shortness of breath, blurred vision, dizziness, irregular heartbeat, chest pain, cold feets, hands, and clammy skin due to the amount of blood lost.

They can faint if overuse is severe enough and may require a blood transfusion to help them recover. Alternatively, eating well and resting for 14  hours (without using their quirk) will  allow the body to replenish what was lost.

Moreover, for maintenance they must take supplements containing vitamin E (antioxidant that protects red blood cells from being destroyed by free radicals [aka: oxidative stress]), Folate, iron, and vitamin C (antioxidant that stops iron from being oxidized) to make up for the blood lost in a fight.

In addition, they need to drink plenty of water to avoid getting gout (needle like uric acid crystals) which forms due to the high cellular turnover when the body is making up for the blood loss.
