Nero the Sable Nero the Sable is an antagonist in " Dirge of Cerberus - Final Fantasy VII - " . He rarely leaves Weiss ' s side in the ruins of Shinra Electric Power Company , and is not seen to have a friendly relationship with anyone but Weiss . Nero is his assistant and leads the Tsviets while his brother is incapacitated . He acts only for Weiss and Deepground ' s cause , except for occasionally tormenting Vincent or Shelke . Profile . Appearance . Nero is a thin man with long unkempt black hair and magenta eyes with feline irises . A mechanical pair of wings spreads from his back . Nero makes regular use of his metal apparatus , but while they resemble wings , he cannot use them for flight . Nero wears a gray Mako suit with straitjacket arms that are at first secured , but later broken at the elbow revealing tattoos extending to Nero ' s wrists , and gray , plain mid - calf boots with blue soles . Strips of metal cover Nero ' s face . He fights with stylized handguns and sparks of darkness rotate around him forming an X in front of him . Nero speaks with a dry English accent . Nero ' s wields guns ( from their appearance , possibly handguns based on the real life IMI Desert Eagle ) , two of which are carried by him and used by his mechanical hands , and later two identical ones drawn from darkness , which he uses with his real hands . Nero can use the arm or blade sections of his ' wings ' as melee weapons . Personality . Nero ' s personality matches his dark powers . He is the opposite of his older brother , Weiss : quiet , brooding , impassive , and unemotional . Because Weiss is his only family and has always treated him well , Nero harbors an obsessive love for him , almost to the point of worship . Nero explains to Vincent that Weiss was the only one to have ever loved him , and Nero would only ever love Weiss . Thus , he is prone to explosions of aggression should anyone threaten Weiss or his plans . Nero is blind to his brother ' s true intentions , and whether he has any personal ambitions or beliefs is unknown . There are many conflicting aspects of Nero ' s personality , with the contradictions centered around Weiss : his older brother ' s strengths balance out many of Nero ' s weaknesses , but simultaneously inspires extreme dependency and lack of emotional control . This paradoxical temperament makes Nero ' s behavior unpredictable . Although he is mentally unstable , having been created through unethical bioengineering and human experimentation , he is among the more levelheaded of the Tsviets . Though he acknowledges his fellow Tsviets as allies , he only maintains relationships with them for as long as they prove useful in achieving his brother ' s goals , and is unconcerned with their eventual deaths . Ultimately , Nero only genuinely cares about Weiss . He bears the same loathing and deep - seated mistrust of humanity as the rest of Deepground , with its roots in the brutal treatment he has received over the years . In his view , the humans who performed these experiments are more like monsters than himself . As much as he hates humans , Nero is not as prone to indiscriminate slaughter as Rosso the Crimson . Nero has no qualms about murder if his brother ' s plans demand it , but he has enough self - control to kill in moderation . Abilities . Nero can manipulate and manifest darkness , gained from the Mako associated with the dark being Chaos , which he can use to move people and objects or absorb them into darkness within or without him . He can create objects and possibly people from the darkness , as seen when he makes copies of his guns . The Mako gives him enhanced versions of the abilities usually associated with a SOLDIER member . Nero ' s abilities require him to wear a suit which constantly supplies him with Mako . It is implied Nero ' s absorbing people into darkness kills them . Shinra feared Nero ' s abilities , deciding to place the straitjacket - like restraints on him to suppress his abilities and chaining him in Mako Reactor 0 . Nero was unable to free himself alone , but the restraints failed to suppress his abilities and have him surrounded by sparks and wisps of darkness . Nero is capable of free flight , much like Sephiroth , but slower . Story . Birth . Born in 1987 , making him 23 years old , Nero is the biological younger brother of Weiss the Immaculate , and the only successful test subject of the stagnant Mako experiments . The experiment was based on the Omega Report s left by Grimoire Valentine and upon Nero ' s birth a vortex absorbed his mother into another dimension . The scientists of Deepground discovered Nero has power over darkness and confined him in a suit of Mako to contain his power . Nero , Weiss , and Rosso continued their training and grow stronger over the years to the point they were feared to be too powerful to control and Nero ' s arms were bound to prevent him from using his hands to manifest his dark powers . Nero was chained inside Mako Reactor 0 . " Crisis Core - Final Fantasy VII - " . Nero and Weiss are released and sent to retrieve Genesis Rhapsodos after he is defeated by Zack Fair . Nero and Weiss take Genesis ' s body away in a helicopter under secret orders from President Shinra and inform Genesis of the Deepground situation and ask him to join them in an upcoming rebellion against the Restrictors , but Genesis refuses . " Dirge of Cerberus - Final Fantasy VII - " . Weiss was taken over by the digitized mind of Professor Hojo . Hojo ( as Weiss ) taught to Nero " the secrets of rebirth " and Nero learned of Lucrecia Crescent ' s theorem of the Planet ' s ultimate and final weapon , Omega , and its herald , Chaos . Nero ordered the Tsviets and Deepground under his brother ' s name to make a pure stream of Mako ( in Hojo ' s words ; Lifestream untainted by either Jenova or G - Substance ) and to search for the Protomateria to bring about and control Chaos . Shelke ' s findings of Lucrecia ' s data led to information about the ex - Turk , Vincent Valentine , whom the soldiers were ordered to pursue . Although not seen in Edge , it is likely Nero was there , as a small group of World Regenesis Organization ( WRO ) troops was sucked into darkness . While Vincent is searching in the abandoned Shinra Mansion , one of the Cait Siths encounters Nero in the heart of the Deepground complex beneath Midgar , Mako Reactor 0 and Nero summons darkness to engulf the cat . During the WRO assault of Midgar Nero does not engage in the fighting with the ground assault , but discusses tactics with the Tsviet commanders . He teleports onto Cid Highwind ' s ship , the " Shera " , and wreaks havoc in the engine room by absorbing the engine room crew into darkness . Shelke enters and after a conversation , they fight . He dodges Shelke ' s attacks and tries to destroy her with the darkness . Nero watches over Vincent as he descends through the Shinra Building . He sees Chaos emerge from Vincent and slaughter Azul , causing him to decide to " live out his destiny of destruction . " As Nero teleports away , he accidentally drops Shelke ' s cellphone , which allows Vincent to regain control of Chaos . Vincent encounters Nero within the Deepground complex where they duel . Upon being defeated , Nero taunts Vincent about Shelke ' s fate and tries to absorb Vincent into the darkness . As he turns to go , Vincent and Shelke appear from the darkness . He realizes Vincent is immune to the effects as he has Chaos , " a soul wrought of terra corrupt " inside him . The " terra corrupt " is tainted Lifestream , from which Chaos is fully born of and whose darkness is even greater than his own . Yuffie intervenes and , slightly confused , Nero vanishes into a portal , insisting his brother has called him . Nero is encountered in Weiss ' s chamber , where , after Vincent and Yuffie find Weiss ' s seemingly lifeless body , he informs them of Weiss ' s rebirth and the start of Omega ' s awakening . The reactor activates and Vincent and Yuffie draw their weapons and attempt to attack Weiss , but Nero kidnaps Yuffie temporarily by sucking her into his darkness and Vincent goes to save her . Upon exiting the darkness and finding Yuffie and Vincent still alive , Nero comments to Vincent that " there are some things that cannot be absorbed by my darkness . " Nero transports Vincent into a hellish world with mysterious floating platforms and crystals above a pool of lava where Nero appears in a spider - like machine known as Arachnero , eventually transforming into Gorgonero . After the gunfight , Nero and Vincent return to Mako Reactor 0 where a fatigued Nero limps off to Weiss . Back in Weiss ' s chamber , Weiss has " reborn . " An excited Nero rushes over to Weiss to embrace him , but Weiss sneers and tells Nero he has no further use of him and plunges his hand into Nero ' s chest throwing him across the room . After it is revealed to Vincent Hojo is in control of Weiss , Weiss and Vincent battle . After losing the battle to Vincent , a shocked and confused Hojo wonders why Omega ' s power has begun to wane . Nero , in a spectral form , appears , and begs for his brother and him to become one so they will never be parted again . When Hojo orders him to leave and stop polluting Omega , Nero ignores him . Weiss , now nearly free of Hojo ' s influence , hugs Nero and Nero fuses into Weiss , freeing him of Hojo ' s control . Weiss walks towards the center of the Mako chamber , with the compulsion he needs to bring about Omega , and vanishes in a ball of light . Nero ' s fate is speculative . He either exists within Weiss , or he may have been destroyed along with Hojo when Weiss entered Omega , being a tainted being . It is possible he survived as tendrils of darkness are seen within Omega and the anguish of tortured souls can be heard , implying it may have been corrupted by Nero ' s darkness . Gameplay . Nero is fought at the end of Chapter 10 . Two other forms , Arachnero and Gorgonero , are fought in Chapter 11 , with no pause between forms . Voice . Nero is voiced by Ryōtarō Okiayu in the Japanese version . He shares his Japanese voice actor with Quon Yobatz from " Final Fantasy Type - 0 " and Setzer Gabbiani and from the " " series . He is voiced by Mike Rock in the English version . Etymology . Similar to his indirect namesake , Nero was responsible for his mother ' s death , although in Nero ' s case , it was accidental . Therefore , his name is essentially " Black the Black " .
