Jacob Kane

Jacob Kane is a fictional character appearing American comic books published by DC Comics. Kane debuted in the Batwoman, created by J. H. Williams III and Greg Rucka.

Jacob and his wife Gabrielle "Gabi" Kane were both soldiers in the U.S. Army (he was a member of the 3rd Special Forces Group and she part of the 525th Battlefield Surveillance Brigade), and are the parents of Kate Kane and Beth Kane. The Kanes are Jewish and Jacob inherited vast wealth along with his other siblings. Bette Kane (the superheroine known as Flamebird, and later Hawkfire) is his niece and Bruce Wayne is his nephew, since Martha Wayne was Jacob's sister.

Kane is promoted to colonel and assigned to NATO headquarters in Brussels, Belgium. When the twins turned 12 years old, their mother took them to a restaurant for a birthday dessert, despite Jacob being away due to a security crisis. A terrorist group (later revealed to be the organization known as the "Many Arms of Death") kidnapped the family during their trip, and Col. Kane led a rescue mission to save them. During the raid, Gabrielle was murdered by the terrorists. The terrorists kidnapped another young girl and murdered her too. Kate, seeing the body of a young girl under a blanket, is left with the impression her sister died. Col. Kane, however, knew that the terrorists had Beth. Despite looking for years, Col. Kane never found Beth. He never told Kate that Beth might still be alive. Col. Kane remarries years later to Hamilton Rifle Company heiress Catherine Hamilton, who becomes Kate's stepmother.

Jacob's emotional steadiness proved to be a major source of stability for Kate in the aftermath of the tragedy, and she sought to emulate that for herself and follow him into Army service, which Jacob supported. Thanks to his higher rank, Jacob was able to be more present in Kate's life during this time. He taught Kate how to box when she was a teenager, accompanied her to R-Day at West Point when she was an incoming freshman, and is implied to have given Kate ringside coaching during an academy championship boxing match that helped her win the fight. Kate's resignation from the academy due to DADT allegations took Jacob by surprise, but he immediately accepted her when she came out to him.

After Kate became a vigilante, Jacob aided her campaign against crime by organizing her training, designing her Batwoman suit and gear, developing her operational headquarters, and maintaining radio contact with her during patrols to provide information and advice.

The Alice persona kidnaps Col. Kane, who immediately recognizes as his now-grown daughter Beth, and uses him to gain access to a military base near Gotham City. She seizes chemical weapons from the base and intends to kill everyone in the city by dispersing them from an aircraft. Alice falls into Gotham Bay during her final battle with Batwoman after revealing her identity, and is again presumed dead.

In 2011, DC Comics rebooted the DC universe through "The New 52". Jacob's history of losing his wife and what happened to Beth remains intact, as well as his support for Kate's campaign as Batwoman. In addition, the New 52 establishes that an informal group of Jacob's closest friends within the special operations community, known as the Murder of Crows, were the ones Jacob assembled to conduct Kate's Batwoman training.

Jacob has been depicted as a highly decorated soldier, appearing with the following awards: the Army Achievement Medal, the Kosovo Campaign Medal, the Afghanistan Campaign Medal, the Iraq Campaign Medal, the Global War on Terrorism Expeditionary Medal, the Global War on Terrorism Service Medal, the NATO Medal for Kosovo, the Kuwait Liberation Medal, the Presidential Unit Citation, the Meritorious Unit Commendation, the Army Aviator Badge, the Air Assault Badge, and the Combat Infantryman Badge.

On the planet Blor, he faced a 20 year sentence, he volunteered for a scientific experiment, a satellite that required a test passenger. He favored dying in deep space to rotting in jail, with the added bonus of a 10,000 to 1 chance of surviving the test.

He was loaded in the satellite together with a laboratory dog, and the satellite was shot into deep space, never to return. To pass the time, they watched a telescopic viewer of Earth and learned of Superboy's existence. On their course for Earth, they passed through a cloud of gaseous Kryptonite, which gave him and his dog Kryptonite-based powers. This incarnation is most well-known pre-Crisis on Infinite Earths from his appearance and death in the non-continuity story Superman: Whatever Happened to the Man of Tomorrow?. In this story, he is depicted as somewhat older and uses the name the Kryptonite Man.

Alien version

A second Kryptonite Man appeared in Superman #397. He was the ruler of a race of humanoids who inhabited Krypton eons before Superman's ancestors. When a nearby cosmic body threatens life on Krypton, Kryptonite Man sends his people into stasis underground. He awakens on the day of Krypton's destruction, during which the mountain he is in is launched into space. He feeds on the mountain's Kryptonite radiation and becomes dependent on it to survive.

Superman clone

In the Post-Crisis era, the Kryptonite Man appears in Superman (vol. 2) #43 as a green-skinned clone of Superman created by the New Gods Simyan and Mokkari.

Captain Atom creation

A character in the ongoing series Superman/Batman also uses the name Kryptonite Man. This version of the character is created when Captain Atom absorbed the explosive energy from Major Force, then went out to destroy a Kryptonite meteor. The Kryptonite energy somehow combined with the remaining energy from Major Force in Captain Atom to create a sentient energy force. After being siphoned from Captain Atom by the Toyman, the energy was able to jump from body to body, taking over the personality and causing the body to release Kryptonite radiation.

K. Russell Abernathy

After DC Comics' One Year Later jump, a scientist named K. Russell Abernathy was working on an experiment to use Kryptonite to develop a new energy source using isotopes. The experiment explodes, infusing Abernathy's body with radiation. Clark Kent, powerless, summons the current Supergirl to contain him. The transformed Abernathy, in a misguided attempt to prove his energy theories, goes on a violent rampage; this includes deliberately attempting to injure Kryptonians. He is soon subdued and imprisoned in Stryker's.

Lex Luthor sends insectile warriors who free Abernathy from the prison. Abernathy is used in conjunction with large amounts of Kryptonite to free an ancient Kryptonian spaceship from Sunstone. He later resurfaced in Action Comics #853, having Superman beaten until the intervention of Jimmy Olsen and Krypto.

Clay Ramsay

In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Kryptonite Man is reintroduced in Action Comics #5, by Grant Morrison and Andy Kubert. His origin is told in Action Comics (vol. 2) Annual #1 (2012) (penned by Sholly Fisch).

In this origin, Clay Ramsay was an abusive husband living in Metropolis. One night, Superman broke into his house while he was beating his wife and threw him into Hob's Bay. His wife subsequently left him and no one in the justice system could help him. Seeking revenge, he joined the mysterious "Project K-Man" (a private super-soldier project) after receiving an invitation from Dr. Abernathy (a nod to the pre-New 52 version of the character). Gaining superhuman powers, he attacked Superman but was defeated and arrested. He was released shortly afterwards by Sam Lane who believed he was needed as a countermeasure to keep Superman in check. K-Man agreed under the condition that the General would help him locate his wife. It was revealed that Lex Luthor had played a major role in the K-Man's creation. Also (as revealed in flashback), he had stolen Kryptonite crystals from the government while being employed by them.

His subsequent activities are unknown, but a version of him from the near future was a member of the Anti-Superman Army. He was seen alongside two people with similar powers (one equipped with Red another with Blue) as part of a group called the "K-Men".

Alternate versions of Kryptonite Man

In the Elseworlds storyline Superman: The Last Family of Krypton, when Jor-El and Lara accompany Kal-El to Earth, they have two more children, Bru-El and Valora, whose genetic potential is slightly 'stunted' compared to their brother due to them being born on Earth. As part of his vendetta against the El family, Lex Luthor is able to turn Bru-El against his family, using a series of nanites designed to make him immune to kryptonite to make him essentially addicted to it, transforming him into a kryptonite-powered superhuman with too little willpower to defy Luthor's orders. He subsequently kills his mother in the attack on the El compound, but Kal-El is able to defeat his brother when he expends too much of his energy. With Luthor's plot defeated, Bru-El is purged of the nanites, at the cost of losing his memory; with Lara's last words being that Bru-El never learn of his role in his mother's death, he is last recorded as having reached an eighth-grade level following his mindwipe.
