Hybrid Evolution Method

The Hybrid Evolution Method or HEM for short is a method of making a Hybrid (half demon half human) evolve beyond their normal capabilities. Normally Hybrids are able to enter a sort of demon form but their power is not at its maximum. They are restricted by the human side of them, preventing further evolution. Dorothy Blackwell a researcher of demons created a theory and tested it. It proved successful and became a method known by her and anyone close to her for evolving beyond normal hybrid power.

Dorothy's theory was that by using a magic sealing stone fashioned into an arrow shape the user could surpass their limits. They have to stab themselves through the heard with the stone while simultaneously activating their demon form. What happens is the magic sealing stone locks away the eternano during their evolution, forcing them to become a pure demon. Within this new form the demon side is completely dominant while the human form is locked away. The user is still capable of using magic however it is now made of demon particles making it technically a curse. Their attributes are also increased by tenfold, making them monstrous even without their powers. However such a powerful transformation has limits. The user must have a high enough regenerative factor to survive the piercing of their heart. This form is also temporary as their technically still human body cannot handle the transformation for a long period of time. There has however been one recorded instance where the transformation has become permanent. The excruciatingly strong demonic energy of the Bonez bloodline causes the transformation to lock. This is not an extremely good thing however. Based on the power of the individual they can only activate their now curse power a certain number of times. Each time they activate it the demonic grip becomes weaker and the human stronger. Eventually their transformation will take a full turnaround and their human side will once again be dominant, all demonic powers and abilities restricted from them for quite some time. Eventually however they will return to how they were before the transformation ever occurred.
