Coalescence(Yuma's Ability): Coalescence is Yuma's natural forte, the ability to share someone else's ability. There are two conditions for its activation: 1. The person must grant permission to share their ability. 2. The person's hand must be held while the ability is active. This can also be used with Zero to deepen the bond and even allow Yuma to use Zero's abilities even if Zero is separated from him.

Symbiote Biology(Zero's Abilities): Even without a host, the Zero symbiote is capable of freely extending its biomass into tentacles and tendrils, and usually manifests it's head. also able to take on humanoid form without a host for brief periods. When bonded to Yuma, it can shapeshift to mimic any type of clothing whatsoever, as well as blending Zero in with his surroundings, rendering him invisible.

Wall-Crawling(Zero's Abilities): another ability courtesy of Venom, The alien costume replicated his ability to cling to walls by controlling the flux of inter-atomic attraction between molecular boundary layers. This is useful for Yuma in times where he has to avoid Peacekeepers.

Yuma's History: Not much is known of Yuma's background, but the Prologue - WDO vs. Amaterasu Corporation suggests that he comes from a city like Kanai Ward since he remarks that the scenery of Kamasaki District makes him feel nostalgic. In Chapter 3 - No Longer A Detective when he examines Shachi's corpse and the gun placed in his right hand, Yuma says that he sort of remembers the feeling of gripping a gun's handle and the smell of gunpowder. This also suggests that Yuma received gun training at some point in the past. At some point prior to the events of the game, he became Number One of the World Detective Organization. As Number One, he was able to solve cases on his own perfectly. He also had a body double due it being the stand protocol for the directors of the WDO and to hide true identity from his enemies. Three years before the events of the game, the Unified Government obtained samples of Number One's DNA and created the first perfect Homunculus. Number One eventually found out about this and how it could have tied to the Great Global Mystery. He grabbed the Book of Death that Shinigami was sealed in from the WDO's underground book vault. On his way there and when he was leaving, he encountered the real Yuma Kokohead. Realizing that he couldn't solve Kanai Ward's Ultimate Secret on his own, he made a plan where he would swap places with the real Yuma, use the power of the Book of Death, and give himself amnesia so he could allow himself to accept help. At the storage room of a train station where the Amaterasu Express was at, he opened the Book of Death and made a pact with Shinigami. He promised her that he'll show her a world where everyone is happy. Before he lost his memories, he also submitted a letter of resignation. He hoped he could bring change to the organization and have detectives follow their own creed by quitting.

Superhuman Stamina(Zero's Abilities): Zero is also capable of surviving in harmful areas for long periods of time such as underwater or in toxic gases produced in Dr. Huesca's lab, the symbiote filtering breathable air to the host.

Zero's History: when Knull comes into existence and creates the Symbiotes from the Living Abyss, he began to realize that some of his kin can be "Corrupt" and break off the hivemind. So long ago he created Zero, essentially a Punishment for any Symbiote that defies him. In order to make him able to do this he gave him a wildcard DNA which allows him to inherit the abilities of all other Symbiotes, ones that exist as well as ones yet to come. This is essentially like a Parallel to Yuma, where his Coalescence allows him to use other's abilities only in this case instead of being either born or working to create the forte, Zero was created with it already in his system. The problem arose with the Intelligence that Zero obtained, because of all of this special power it gave him his own personality, and ironically made him a "Corrupt" Symbiote. The very thing he was created to destroy. As evident when he spares Venom himself when he became Corrupt. Because of feeling Mercy, Zero was deemed a failure and as such Knull had the Symbiote-dragon Grendel attempt to kill him. Fortunately before Grendel could kill Zero in earth, the very first Number One who established the WDO unintentionally saved it, forcing Grendel back into space with vicious wounds and nearing death yet Knull assumed he was successful. Zero would be stuck under one of earth's seas for a very long time under a rock that was on top of him, but after many years, Kanai ward's train system was built and the constant shaking of the bridge above water eventually slid the rock just enough for the Symbiote to escape to Kanai Ward. Likely trying and failing to find suitable hosts until a happenstance Yuma is investigating one of the dead people since they just dropped dead when the Symbiote deemed them unstable for it, the investigating is what binds Yuma with Zero.

Webbing Generation(Zero's Abilities): The symbiote can convert its constituent matter courtesy of Venom into strands of Indigo or black webbing, which it can shoot from the back of its hands at high pressure up to a distance of 70 feet. The alien’s substance seems to be composed of tough, flexible fibers of organic polymers, which regenerate swiftly after "shedding." The strands have extraordinary adhesive properties, which diminish rapidly once they abandon their living source. After about three hours, with no source to nourish them, the strands dry up like dead skin and dissolve into a powder. The strands possess a tensile strength of 125 pounds per square millimetre of cross-section. Yuma and Zero commonly use this ability to string up to high places as well as reach evidence that may be too high for the detective to reach, it also allows for Yuma to trap peacekeepers without killing them.

Superhuman Strength(Zero's Abilities): Courtesy of Venom when he inhabited Eddie Brock, Zero gave him enough strength to lift 11 tons, making him more powerful than Dominic Fulltank. However, his full strength often fluctuates. Yuma often uses this to simply kick away enemies so they will be far enough away to maybe think about their life choices.

Superhuman Durability(Zero's Abilities): Zero's body is highly resistant to physical injury, capable of withstanding assault from high-caliber bullets as well as attacks from super powered individuals. When distributed at a typical thickness over Yuma's body, the symbiote is capable of absorbing bullets from small-arms weapons firing conventional ammunition. Yuma often uses this to defend his fellow detectives from the bullets of the peacekeepers.

Regenerative Healing Factor(Zero's Abilities): Zero is capable of healing injuries in the host at a faster rate than normal human healing allows. The symbiote is also capable of healing injuries and illnesses that current human medical care cannot such as cancer. The symbiote has enabled Yuma to recover from injuries that should have been lethal such as a single blow from Dominic Fulltank's arms or a whip from Yomi's whip.

Telepathy(Zero's Abilities): Like others of his species, Zero was able to psioniclly and biochemically communicate with Yuma AND shinigami through Yuma's pact. It was the fact he was able to use the telepathy to befriend shinigami that allowed him to ease into Yuma easier than most Symbiotes start with.

Empathetic Empowerment(Zero Abilities): The Zero symbiote, like others of its kind, is capable of feeding off its host's negative emotions - chiefly rage, hatred, and bloodlust - in order to augment itself. However, he can also empower himself with Positive emotions like Relief, glee, happiness, and ecstasy making him abnormal among other Symbiotes.

Poisonous/Venomous Fangs(Zero's Abilities): An ability developed by Eddie Brock upon bonding with the symbiote Venom and thus copied by Zero. It was revealed that this set of fangs not only intimidates foes but can deliver a powerful, venomous bite. When combined with Yuma however, the Venom is able to change between as lethal as a Komodo Dragon bite or as lethal as a cone snail sting.

360-Degree Senses(Zero's Abilities): Courtesy of Carnage, Zero the symbiote possesses a form of full-body receptory system, in that each individual cell is capable of acting as an eye, ear, mouth, nose, or tastebud. This is very important for Yuma as it allows him to not only detect Peacekeepers before they get the drop on him as well as find Culprits that are hiding in the very room.

Size Manipulation(Zero's Abilities): Stolen from a Venomized Ant-Man, Zero can alter his size with Yuma.

Constituent-Matter Generation(Zero's Abilities): The symbiote can use the living abyss comprising its matter to generate tendrils and pseudopods, and can use this for lethal effect against culprits and other Symbiotes courtesy of Venom and other symbiotes. This is most-commonly utilized to create bladed armaments such as swords, spikes, bludgeons, knives, claws and axes; though the symbiote once morphed its host's arms into a pair of bat-like wings by morphing the cape into the arms. The symbiote can also discharge its biomass as projectiles

Digital Immersion(Zero's Abilities): Zero can send his symbiotic biomass and Yuma's vision into the Internet by splicing his molecules through Ethernet cables to travel between hard-wired computers systems allowing the two to investigate classified information as well as destroying said areas of the internet that may be suspicious. Courtesy of Carnage.

Hell-Mark(Zero's Abilities): Courtesy of Carnage stealing from a version of Andrea Benton, the demonic sigil gives him an assortment of demonic abilities. but Yuma hesitates to Use them.

Cleansing Touch(Zero's Abilities): Courtesy of Carnage Stealing from Anti-Carnage and Anti-venom, Zero can produce antibodies that purge others of impurities such as toxins, drugs, diseases, and other malignant substances through physical contact; being especially potent against other symbiotes -- Yuma may also be able to use this to revert a Zombified homunculus back to a living state.

Hellfire Conjuration and Fire Immunity(Zero's Abilities): With the Hell-Mark Courtesy of Carnage's theft, Zero is able to conjure and manipulate hellfire much to Yuma's sometimes reluctance. As a side-effect of its ability to conjure hellfire, the Hell-Mark makes them immune to fire when it would have devastated other Symbiotes.

Electrostatic Energy Generation(Zero's Abilities): The power to manipulate and generate electricity, stolen from a Venomized version of Electro, courtesy of Carnage's stealing, Zero and Yuma use this ability to cause power outages in areas that might be locked by a digital lock and thus allow Yuma to get into a place that was once forbidden. This also allows Zero to give a shocking backhand to Peacekeepers in the way.

Transformation - Water(Zero's Abilities): Courtesy of The ability of Hydro-Man, stolen by Carnage when he absorbed his Soul Molecule. Under Zero and Yuma's usage this ability gives his symbiote biomass greater fluidity and the ability to augment its humanoid form

Scanning(Zero's Abilities): Courtesy of Scorn, Zero can scan anything and analyze the data and information that is gathered, including not just technological and digital subjects, but also subjects that are biological, chemical, etc. This is by far the most useful power that Yuma uses as it allows him to gain information on cases faster.

Trichokinesis(Zero's Ability): Courtesy of the Scream Symbiote, Zero can extend Yuma's question mark Ahoge in order to duel and lacerate the opponent if Yuma is forced to his knees.

Post-Cognition(Zero's Abilities): Courtesy of Chakram, Halara Nightmare's original Symbiote that enhanced her forte. Zero and Yuma can see a murder scene from the perspective of the third party, the person who found the body which allows both to figure out if something was tampered with in the crime scene's timeline.

Acid Generation(Zero's Abilities): Courtesy of Agony, Zero could also use his metabolism to spit acid, which could burn through most substances, however the full extent or limit and range of his acid projectiles are unknown as it bases back to the same ability that Agony has.

Techno-Hybrid(Zero's Abilities): Courtesy of Scorn, Zero being able to fuse itself with different kinds of mechanical weapons thus being able to fuse itself with a different kind of technology. This added with Yuma's inherent knowledge on how to use guns and you have a great shot if Zero picks up a gun.

Chemokinesis(Zero's Abilities): Courtesy of the Sleeper symbiote, Zero is capable of producing liquid and aerosol chemicals with a variety of effects - including inducing various emotional states, tranquilizing targets, psychological manipulation, and secreting corrosive chemicals for offensive purposes. This also affords it a form of telepathy, using pheromones to interject its thoughts into others' minds. This also grants it a superior cloaking ability to other symbiotes, generating pheromones to almost-completely mask its presence.It is also capable of using chemokinesis as a means of rocket propulsion, enabling it to traverse space and underwater, and produce acid that doubles other acid based abilities. This may be used by Yuma if he wants to rocket up and away from a circle of peacekeepers.

Night Vision(Zero's Abilities): Courtesy of Zzzxx, Zero can see greatly at night almost as if it was still daytime. A great help for Yuma when dealing with the hazy and rainy city of Kanai Ward.

Disguise(Zero's Abilities): Courtesy of Pheromone, Desuhiko Thunderbolt's original forte, Zero can change Yuma's physical build while in his suit form and mimic someone perfectly down to the voice and height. This can be switched from person to person but Yuma will have to get the Venom suit back around him fully in order to change.

Spectral Projection(Zero's Abilities): Courtesy of Usher, Vivia Twilight's original symbiote, Zero can allow Yuma's spirit to exit his body and float around invisibly and independantly of the Symbiote allowing for the Symbiote to fight while Yuma's ghost investigates a crime undeterred.

Time Warp(Zero's Abilities): Courtesy of Chronocruncher, Fubuki Clockford's own original Symbiote. Zero and Yuma can rewind time for a short period but it greatly exhausts both of them afterwords.
