Appearance: He is a young man in his late teens who is tall, fit, muscular, and lean, considered attractive by others, has fair skin, spiky, disheveled pitch-black hair, with tints of blue, and dark purple eyes. On his back is a large black star-shaped tattoo, with a single, large eye in the center and surrounded by many, smaller white stars. On the upper left side of his chest is a large scar that also covers portions of his left shoulder too. In casual attire, Chad would wear a grey, short-sleeve shirt, over that is gray sweatshirt, followed by a black biker jacket with a gray shoulder pads, fingerless black gloves, gray jeans, a black belt with a golden buckle, and black combat boots. On the back of the jacket is the Magnum Chaos symbol.

Background: Born between the union of the first Primordial god and creator of the universe, Chaos, with a magician/scientist, Alva Walker, who was a rare case for a Legacy, descended from different gods of various religions. Both Chad and his mother were protected by a symbiotic creature named Zero, given to them by Chaos. When he was eight, Chad began fading in and out of existence due to the difficulties of controlling his powers that were connected to the Void. To save him, Alva injected nano-bots of both magical and scientific origins into her son's bloodstream, allowing Chad to control his powers. Sometime later, Alva was killed by servants of Gaea, who had sensed her younger brother's birth, and came to kidnap Chad. When he saw his mother killed, Chad went berserk and erased them from existence. He was eventually found by Hestia, goddess of the Hearth, and brought to Camp Half-Blood. Despite that, he left the camp when he was fifteen and took up the occupation as a hunter of the supernatural, as well as a freelancer, thief, assassin, mercenary, inventor, and bounty hunter. Most jobs he accepted were from Olympus, with Hestia acting as a liaison, and became a mother figure to Chad. He currently resides on Mill Rock, the small abandoned island between Manhattan and Queens, while making North and South Brother Islands his secondary bases. Chad Walker is also listed among the "Top 10 Strongest Beings in the World". Chad is also Yaldaboath, the entity known as the "God Eater", born between the mix essence formed from the battle between Chaos and God.

Skills & Abilities:

Demigod/Legacy Physiology: Chad possesses the usual abilities of a Demigod, including ADHD and Dyslexia, as well as enhanced capabilities. Constant training and going through real life battles, combined with the effects of Zero, have increased his skills to supernatural levels, breaking his limits. He also possesses indomitable willpower and a strong soul. Due to being a legacy from his mother, Chad also inherited several abilities from the deities he is descended from, some having mutated and merged into new abilities.

Body Supremacy: Chad has complete control of his body, from his muscles, bones, veins and neurons, thus can move with remarkable grace, athletic and acrobatic skill.

Optimal Finesse: From training, Chad can use his skills to their highest potential. Thus, he effectively lowers any chance of failing to complete a set task or risks that may result in an undesirable outcome. He has complete and utter control over his skills and instinctively knows which of his abilities will best suit any number of situations.

Maximum Brain Capacity: Has total 100% of his brain capacity, gaining extended knowledge and usage of the allows Chad to think in ways that other could never have imagined or understand.

100% Muscle Usage: Through hardcore training, Chad can use all of his body's muscular strength, maximizing his overall physical strength.

Maximum Concentration Capacity: Chad can utilize 100% of his concentration, allowing him to push his physical and/or mental capabilities to their maximum potential. This let's Chad perceive and respond without any distraction, with obstacles becoming minor problems while objectives grow significantly easier to accomplish.

Flawless Coordination: Chad's physical abilities are heightened to the point where he can perform any physical act without difficulty. All he has to do is merely imagine himself doing the act in his mind. Then, he is able to perform it without any problem, whether it is free running, to juggling swords, to doing multiple back-flips.

Body Language Analysis: Chad can intuitively read others' body language and anticipate their actions. This also works with his sixth sense when detecting incoming threats and avoid them easily.

Adoptive Muscle Memory: Another interesting trait is that Chad can replicate movements after observation. This includes the use of weapons, martial arts and other skills. Despite that, it takes him some time to fully master them.

Tactical Genius: Chad can mentally adapt to new/changing situations, letting him processes the world in the optimal way. allowing him to have infallible tactics and strategy. This gives him a deep understand how a person thinks and fights in combat.

Regenerative Healing Factor: ad has an impressive healing factor, allowing him to regenerate even fatal wounds and regrow and/or attach limbs. Combined with his ability "Void Mimicry" Chad can recover from nearly any kind of damage.

Nihilikinesis: As the son of Chaos, Chad can manipulate the powers of the void, controlling the Nothingness that makes it. This dark energy is highly dangerous, as at full power it can erase an object or being from existence. Chad can also use the energy to create explosions too, showing it is quite volatile too. Other ways Chad uses it is to shoot it from his dual pistols as bullets or beam, or infused his swords with the dark energy to make them even more lethal. Also, it can be use defensively too, such as creating barriers. Chad can also use it on conceptual targets too, with life and death being an example. Another aspect is that Chad can also negate powers, no matter their origins, though some abilities have certain requirements in order to negate them.

Kenokinesis: A sub-power of Nihilikinesis, Chad can create and control vacuums, the atmospheric region devoid of physical matter and energy. This grants him some control over manipulating air, creating winds of varying levels including tornadoes and hurricanes, reject air to create vacuums and air blasts. It even grants Chad defense against fire and sound-based abilities too. Chad is also able to crush and/or suffocate a person by creating vacuums of air, due to leaving only empty space devoid of air or cause implosions.

Erasure: Another power he inherited from his father. Chad can erase anything. That includes living beings, inanimate objects, healing, powers, space, time, energy, diseases, identities and memories. He can do this by manipulating null energy or simply physical contact. The only drawback is that it takes a lot out of him to erase more powerful targets.

Alteration: A mutation of carrying the essence of the Biblical God combined with the multiple heritages his mother possessed. Chad can change the physical and chemical property of matter and of any object as well as alter the stability of anything. The only drawback is that Chad needs to make physical contact with an object and/or person to do it.

Creation: Stemming from his father and with himself being Yaldabaoth, carrying the essence of the Biblical God, Chad can also create things too. He does this by summoning an ancient form of matter which he named Prima Materia. With that, he can create whatever he desires. However, Chad's abilities are limited to non-living objects as creating life takes a lot of stamina out of him.

Warping: Chad can distort space and time, allowing him teleport to whatever location he wants to go, so long as he possesses a visual of it. He does this by warping in and out of the void, similar to Shadow Traveling, but doesn't need a shadow. Chad can also warp other people and objects with him so long as he is touching them.

Void Mimicry: By accessing the void, Chad can make himself invisible, intangible or imperceptible, thus making him virtually nigh-invulnerable. The downside is that he cannot remain in this form for very long as it takes a toll on his stamina, and that he cannot make contact with other beings or objects unless he was already holding them beforehand.

Storage: Chad can store items into the Void. He is able to summon them later for when he needs them. Whatever he stores remain in the same condition as they were, including food.

Deity Killing: Like his father, Chad also has the capability of killing Gods as well as other beings of similar positions. This also means Chad can kill beings of lesser power too.

Chaotic Form: Chad can take on a form where his entire body is covered in dark energy of the void, allowing him to erase whatever he touches. This is known as the form of Yaldabaoth. The only times Chad uses this form is when he has no other options left because he still has trouble controlling it.

Reality Rejection: By calling forth the Void, Chad can achieve supernatural feats by rejecting aspects of reality. Whatever he does not like or denies, he can reject that reality into something else he prefers, in some cases manipulating space and time. This involves healing what would be considered untreatable wounds, restoring objects and people to what they once were, negate a certain event, and even bring the dead back to life, but takes a large toll on his stamina and he can only use it at least three times a day.

Master Inventor: Having taken an early interest in creating new things, Chad has become a skilled inventor, having created various items during his time. Combined with his magical prowess, the number of inventions Chad has made are near limitless, ranging from armor, vehicles, ships, weapons, and so on.

Weapons Master: Chad is highly skilled in using both various melee weapons and firearms, capable of using both of them at the same time. By combining demigod and legacy abilities, Chad can make his weapons and fighting styles even deadlier. Most notably, Chad is skilled with dual wielding either his pistols or swords at the same time, and can even use his guns as melee weapons too.

Master Hand-to-Hand Combatant: Along with weapons, Chad is quite skilled in unarmed combat, able to fight against even the most strongest and/or fastest opponents. Again, using his magic, Chad can augment his body to gain the advantage, as well as use his Void Mimicry and Teleportation powers when fighting at close combat too, allowing him to take his foes by surprise.

Magic Expert: To not depend solely on his inherit abilities, Chad learned magic from his mother who was a magician. He only uses anti-magic to nullify enchantments, magics and spells, and rune magic for items and traps.

Items:

Zero: A living, black, bio-metallic, high-tech symbiotic being that Chaos gave to Chad when he was an infant, formed from the combination of technology and magic. In its dormant form, Zero can take the appearance of either a black satchel or a backpack that can store an infinite number of non-living objects, such as the various weapons Chad uses, due it being linked to the Void. When Zero merges with Chad, it takes on the appearance of a black and grey armor with a full black body suit underneath along with a helmet and jetpack attached to the back of the armor. The armor's gauntlets can conjure different kind of weapons on the armbands, such as guns, blades, claws etc attached to them. The suit is capable of adapting to various situations that Chad might find himself in, and if the situation calls for it, can also control Chad's body if he is unconscious. The creature will only obey Chad and find him wherever he is, and in its dormant form, will return to Chad's side if separated. Also, Chad can add his leather jacket to the armor, with the shoulder pads and gauntlets over it.

Oblivion: Chad's primary weapon. Oblivion can switch between a double-edge longsword with a navy-blue handle and golden crossguard, to a selective-fire assault rifle. The blade can be infused with null energy, while the rifle can fire null bullets. The weapon can only be wielded by Chad and will return to him on command. If it is damaged, the weapon will repair itself when stored away.

Alpha & Omega: Another gift, given to him by his father, Alpha and Omega are adaptable weapons that can only be wielded by Chad. They can take the form of twin katanas or a pair of semi-automatic pistols. Like Eternal Oblivion, if they were to be separated from him, they will return in three-five minutes. Should the weapons be damaged, then Chad can simply store them away where they will repair themselves.

Stigma: Another weapon of Chad's. Stigma is a shield that appears as a cross between a Heater and Kite shield. The shield can deflect attacks and when infused with void energy, can erase them from existence. This makes it good as a blunt weapon too. Chad can extend the void energy to create a wall to protect nearby allies. Like Oblivion, Alpha and Omega, Stigma can only be wielded by Chad. If he were too lose it, then Stigma would just return back to Chad later on. Also, the shield can be infused with void energy too.

Various Items: Carries a large assortment of items he keeps stored in the void. They are to be used for different situations.
