Origin Silas Burr is a former agent of the
Pinkerton National Detective Agency. In 1912, Burr escapes execution after being found guilty on 22 counts of murder. He travels to a Canadian military base, where employer Frederick Hudson took a special interest in Burr's ability to push the men under his command beyond their moral and emotional limits. In 1959, Burr trains
Daken, who is ordered to destroy the training camp. Burr is mortally wounded by Daken, but is saved by
Romulus, who chooses him to be the prototype for a process that binds
adamantium to his skin.
Modern era In the modern era, Cyber resurfaces in
Madripoor, as an enforcer for an unnamed
drug cartel, where he interferes between the rival crime cartels of Wolverine's ally
Tyger Tiger and General Coy. Tyger bites out the villain's left eye before he falls into a truck containing hallucinogens he had earlier used on Wolverine, leading Cyber to flee.
Resurrection Cyber resurfaced in
astral form and possesses the mutant Milo Gunderson, who has superhuman strength and childlike intelligence. Intent on revenge, he sets off for the
Tinkerer, who bonds adamantium to his new body. Unbeknownst to Cyber, Milo's body has a weak heart, which causes him to have a heart attack during a battle. His condition worsens, and Wolverine is forced to bring him to the Tinkerer to treat him. The Tinkerer agrees to construct a
pacemaker to stabilize Cyber's heart condition in exchange for the use of Logan's carbonadium synthesizer. Cyber is later killed by
Ogun, who tries to sell his adamantium carapace to
Abraham Cornelius after dissolving the rest of his body in an acid bath.
Hornet Under unknown circumstances, Cyber returns to life and masquerades as
Hornet, a member of the
Slingers. He is first seen in Las Vegas following
Hydra's
takeover of America, having been hired by Forbidden City casino owner Silas Thorne to stage a robbery of a food delivery being sent to the casino of Cassandra Mercury. Hornet summons the Fhtagn, a demonic creature, to attack Scarlet Spider and
Ricochet, but is forced to work with them when the Fhtahn grows out of control. It is later revealed that Cyber was resurrected by a demon who had been impersonating
Black Marvel.
Possessed by Adamantine Sometime after abandoning his Hornet identity, Cyber decides to hunt down Wolverine to settle the score with his old foe just before Wolverine
relocates to Krakoa. Despite him and all other mutants being granted amnesty on
Krakoa, Cyber does not visit Krakoa due to the presence of more powerful mutants in Wolverine's company. After
Krakoa's fall, Cyber ambushes Wolverine while he is living in solitude in Canada but is fought off. The fight between the two unearths a mass of sentient
Adamantine, which possesses Cyber and turns his adamantium implants into golden Adamantine. Hoping to rid the world of adamantium for being a "false metal", the Adamantine has Cyber target those with adamantium weapons including
Lady Deathstrike,
Constrictor and
Donald Pierce, who are also possessed and transformed like Cyber. Hoping to prove himself as the Adamantine's champion, Romulus has Cyber and the others attack several adamantium factories across the United States to lure Wolverine to kill him for the Adamantine. When Wolverine and
Laura Kinney are drawn into a battle, Romulus absorbs the Adamantine from Cyber and the others to empower himself, which knocks Cyber and the Adamantine's hosts unconscious. ==Powers and abilities==
