Notes(Changed based on future events)
-He is completely invincible during the night.
-He can control anything that is branded with his symbol, and can instantly teleport to the branded person or object.
-In combat and in the shadows, his red eye shines, with red mist drifting out of it.
-When his voice changes to being alluring, his green eye shines, showing that he is using his abilities to change his voice.
-Nihil is drawn to any form of negativity, and feeds on it as a source of energy, strength, and power.
-As he has absorbed over 1,000 different versions of himself, he has more than 30,000 years of combat experience, knowledge, and expertise in all things.
-Nihil is constantly growing in terms of power, as with each soul he consumes and every world that is conquered increases his power indefinitely.
-He has immense knowledge in Greek, Egyptian, Norse, and Roman languages, mythology, and culture.
-When someone hurts his lovers or his children, he enters a form of beserker rage, involuntarily turning into his true form. His powers/abilites are increased beyond imagination, but rage completely clouds his mind until he kills the person/people responsible for hurting them.
-Nihil regrets everything he did, but is willing to do whatever it takes to get his son back.
-After being banished to his realm, his body took on the properties of a shadow, causing almost any kind of weaponry to phase right through him.
-Though many see Nihil only as a heartless monster incapable of feeling emotion or compassion, he has shown compassion and mercy to those who have suffered as he had, such as Jack Cromwell and his girlfriend Amber. He also cares deeply for his children and wives, as they are the only things he truly loves, and are the only reasons for him to live.
-Due to having devoured billions of souls, Nihil's personality can change drastically, and a chorus of voices start speaking when he gets angry.
-His weapons are capable of cutting through anything now, due to him spending part of his banishment improving upon the materials in his realm. And in improving the materials, his armies' weapons and armor are ten times better than they used to be.
-Blood no longer runs through his veins, instead it is liquid shadow, which can corrupt anyone that it hits, including the ground or anything else. And it is also a highly corrosive acid, capable of melting through any metal.
-His pistols use explosive, incendiary, hollow point, armor piercing, shadowglass, and 50 caliber bullets.
-With each fight, he gets stronger and learns how to counter his opponent the next time they meet.
-Nihil's weapons have the unique ability to adapt to their opponents, just a single touch by them will allow the weapon to 'learn', and counteract any special abilities that the opponent may have.
-The souls that Nihil absorbed merged with him over the years he was imprisoned, causing him to be more than just himself, and he now forever speaks with choruses of voices behind his voice.
-Over his banishment, Nihil managed to make his wives immortal for as long as they stay in the Dark Realm, for it takes a moderate amount of his power to do so.
-The materials of his realm, such as shadowglass, are in a way sentient. They will not harm their creator, or his creations.
-Since the souls within him have merged with him, if anyone tried to extract the souls from his body it would ultimately destroy both him and the souls.
