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 light grey, short-sleeve shirt, over that is dark gray sweatshirt, followed by a black leather jacket shoulder pads, fingerless black gloves, black jeans, a black belt with a golden buckle, and black combat boots. On the back of the jacket is a yellow Magnum Chaos symbol.

Background: Born between the union of the first Primordial god and creator of the universe, Chaos, with a mortal woman named Alva Walker, who was in fact a legacy of Hecate. Both Chad and his mother were protected by a symbiotic creature named Zero, given to them by Chaos. When Chad was eight, 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".

General Abilities:

Demigod/Legacy Physiology: Chad possesses the usual abilities of a Demigod, including ADHD and Dyslexia, as well as enhanced capabilities including strength, speed, durability, agility, reflexes and endurance. Constant training and going through real life battles, combined with the effects of Zero, have increased his skills to supernatural levels, breaking his limits. This includes having complete control of his body, 100% access to his brain, perform any physical acts without difficulty, use all of his muscle strength, intuitively read other peoples' body language and anticipate their actions and replicate movements after observation. 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.

Fighting Instincts: Through training and his demigod heritage, Chad naturally possess an automatic response mechanism to win in combat. This allows him to understand how a person thinks and fights in combat. And through training Chad can use his skills to their highest potential and instinctively know which of his abilities will best suit any number of situations. This also lets Chad utilize his full concentration, letting him to push his physical and/or mental capabilities to their maximum potential, perceiving and responding without distraction, obstacles becoming minor problems while objectives grow significantly easier to accomplish.

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.

Hyper Intuition: Chad is gifted with the ability to instantly learn and understand the complexity and exactness of organisms, objects, etc. without the need of long-term or special education. This can range from abilities, combat, movement, weapons, mechanics, magic, and traps. It even allows Chad to make the best of one's abilities and detect impeding threats. He can then adapt them for his own needs/uses.

Regenerative Healing Factor: Chad has an impressive healing factor, allowing him to regenerate even fatal wounds and regrow and/or attach limbs. However, it takes time depending on the amount of damage he has taken, but combining it with his void powers, Chad can increase the speed of healing.

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 in the form of gun kata.

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.

Demigod Abilities:

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. That includes living beings, inanimate objects, healing, powers, space, time, energy, diseases, identities and memories by making physical contact. Other ways Chad uses it is to shoot it from his firearms as bullets or beam, or infused his swords with the null 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 and even reject reality, though it is difficult. Another aspect is that Chad can also negate powers, no matter their origins, though some abilities have certain requirements in order to negate them. Finally, Chad can make himself invisible and imperceptible or intangible, thus making him virtually nigh-invulnerable and undetectable. 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. This power has also granted Chad several sub-powers too.

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.

Ourano-Chronokinesis: 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. This also allows Chad to 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.

Gyrokinesis: Chad has some powers of gravity. Mainly, he uses the ability of attraction and repulsion, using it as a form of telekinesis. Furthermore, Chad can also increase or decrease the gravity in a specific area. This can also be used on himself, granting him levitation and flight. On rare occasions Chad can even create black holes.

Creation: Stemming from his father, 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 and he needs to know the basics of said object in order to make it, so decided to learn alchemy to help.

Legacy Abilities:

Mystokinesis: As a legacy of Hecate, Chad is capable of using Magic. The most prominent ability of this is that Chad can change the physical and chemical property of matter and alter the stability of various things of whatever he touches. This mostly includes making the layer/surface much harder without losing any mobility or make substances susceptible to warping, bending or breaking. It has several connections to Alchemy and Enchantment.

Mist Control: As the son of Chaos and a legacy of Hecate, Chad has better control over the mist than most demigods. With it, Chad can create illusions to fool mortals and even monsters. He can even manipulate the memories of others, hide people and locations, create disguises and so forth. Chad mostly uses this to hide his house from mortal eyes or when he makes an order for take out and other needs.

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, a backpack or merge with his clothes, 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.

Eternity: Chad's primary weapon. Eternity can switch between a European longsword claymore with a black blade, 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, letting him channel the dangerous power. The blade and bullets can break through most armor and weapons, but is heavy too. 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, serving as his secondaries. They can take the form of twin katanas or a pair of semi-automatic pistols. They are not as strong as Eternal Oblivion, but are faster and lighter to wield. Like Eternity, the blades can be infused with null energy and fire null bullets, and if they were to be separated from Chad, 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 erase most attacks and objects that touch it. This makes it good as a blunt weapon too. Chad can extend the void energy to create a wall to protect nearby allies. Like Eternity, 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.
