Halfbreed are exactly what the species name entails. Halfbreeds are the product when two compatible supernaturals breed and have children. There are only three types of actual types of Supernaturals that are compatible to create halfbreeds, and only three types of halfbreeds. Those would be Werewolf/Vampire halfbreeds, the rarest of all the halfbreeds due to them being pure miracles and because of how long they've been hunted. The others would be Werewolf/Witch and Vampire/Witch. They look like normal human beings, act like normal human beings, but at the same time are considered to be abominations amongst the supernatural world for hundreds of years. It has caused a war that seems to be unstoppable. Blood "purity" and supermicy has always been on the mind of mose supernaturals, but it seems to really be on the minds of vampires and werewolves, who have naturally been enemies since the dawn of time. Knowing that their kind has breed with the enemy set them off, and now any halfbreeds found whether half witch or not they will be killed.
Werewolf/Witch :: they are mortal, they do not age any differently than their witch and werewolf counter parts. At a certain age, usually around the age of 60, they will no longer be able to change, and their halfbreed status is deminished. They DO need to change on the full moon like their pure bred cousins the werewolves. For if they don't they have to deal with something called "The Rage". Also, their wolf forms are bigger than pure breds because of the witch side giving them more power to use.
Vampire/Witch :: They are not mortal but they are not immortal either. They have the same tough skin as their vampire counter part and are considered to be "half" dead for heart beat can not be detected. But they do need human sustiance to live more than they need blood. They do not NEED blood to live but they will be weak if they don't feed.
Vampire/Werewolf :: Like their vampire/witch cousins they are not mortal nor are they immortal. They DO NOT need to feed on blood period but MUST eat human sustiance to stay alive. They DO NOT need to change on the full moon and can change at will when ever. Their werewolf forms are just barely the size of a normal wolf, the complete opposite of their Werewolf/Witch cousins.
Werewolf/Witch :: they are mortal, they do not age any differently than their witch and werewolf counter parts. At a certain age, usually around the age of 60, they will no longer be able to change, and their halfbreed status is deminished.
Vampire/Witch :: For every two years that pass, they only PHYSICALLY age 1 year. So if a they are only 4 years old, they only look 2 years old. Get it? So if you want them to LOOK 18, they will need to be 36 years old in reality.
Vampire/Werewolf :: Aging is swomwhat like the Vampire/Witches. For every four years that pass they only age physically 1 year. so yea they stay young pretty long. if one LOOKED 20 they would really be 80 years of age.
Werewolf/Witch :: They are allergic to silver just like their werewolf cousins and will have the weaknesses of their power, as simple as that.
Vampire/Witch :: They do have a small bit of blood lust but it is not strong enough to put them into a blood rage. And they feel sick in the sun but they will not burn nor turn into ash.
Vampire/Werewolf :: They don't need to change nor do they need to feed on blood. Vampire/Werewolf halfbreeds are a perfect example of something that has all the strengths but no weaknesses. Sun doesn't harm them, but they usually are small and very weak, lucky to make it past the first few years of life.
