Common Alias: Debtor
Power/Abilities: Since birth, every family member owes a debt. At birth the newborn child cannot sustain itself and therefore their mother must sacrifice herself in order to allow them to live. Because of that reason women are more cherished in the family than men.
The reason why such an event occurs is because of the ability the family member wield. They have complete and utter mastery of their body. They can move their blood, push their muscles to their limit and tear them, adding large amount of calcium to certain bones - moving them close to their skin and using them as shields against blunt force and sometimes even stand against metal swords.
This leaves them crippled, mangled and sometimes resulting at their deaths after certain encounters. To counter this misfortunate side affect, they've developed amazing healing abilities. The abilities do not operate on pure willpower, (unlike most "regenerating" beings) they draw on the biological materials of others, decomposing them and using them as material to restore the body of the user. Furthermore, if a user is hit by a sword or projectile and is bleeding, the user is able to stop the blood flow from leaving his body, thus preventing unnecessary blood loss. A user, with enough skill, can use the blood of a fallen enemy to restore his, the bones of a corpse to restore his ability to walk and their muscles to mend those that failed and teared at combat. The act of sacrifice made by the mother is a complete reversal of this ability, giving life to the newborn infant by sacrificing parts of her body, killing the mother in the process. (In modern times the medicinal science is developed enough to handle most of these births without having the mother sacrifice her life for her child, thus allowing the existence of a normal family cell, with more than one child).
Their offensive capabilities are staggering. They can control their biological material inside of their bodies but also outside of it. They can use their blood as a whip, high velocity projectile or shield, their bones as a shield or a weapons. The only boundaries behind this technique is that constant use of it without rest will result in the loss of too much blood leading to the death of the user. the destruction of their body always follows the offensive path of these users, making them a danger to themselves and their enemies.
Common Features: Every child born as a Debtor will have the name of their creditor engraved on their forehead, the name of their mothers, in order to remind them of the debt they must return when they become parents themselves. As the generations evolved they began growing with excess body parts to increase their chance of survival - whether it may be an extra toe in their feet or another finger, it may be deconstructed and used in emergencies as vital biological material. Many born this way with visible deformities are shunned from society.
On the other hand some may make themselves appear to be beautiful. With their ability to manipulate their biological material they can always have perfect white teeth. They can create muscle mass without much work (though actual energy and material is required) and transform body fat into sugar and protein.
