The Kobra identity is later established as an international terrorist organization that frequently clashes with superheroes associated with the Justice League.

Jack was not particularly happy about this - not that he found it difficult to come up with characters, but, by this point he still wanted to do a novel in comic book format.

At any rate, I typed the whole mess up, beginning with a splash page of a giant robot smashing through a window of a crowded restaurant.

Sitting at Jack's kitchen table, his initial thought was to cut each of us a piece of chocolate cake-something he was still allowed to eat back then.

This first issue then sat in DC inventory for over a year, during which time Kirby left the publisher to return to Marvel Comics.

Pasko later reflected: "I wrote all of Kobra with my tongue firmly planted in my cheek—it was a preposterous exercise dumped in my lap, and it helped pay the rent on a very nice place in the Village".

[4] Kobra is an international terrorist and mad scientist who has crossed paths with the majority of Earth's costumed heroes during his attempts to usher in the Kali Yuga (an age of chaos).

His real name is Jeffrey Franklin Burr, and he was born part of a set of conjoined twins, but was stolen at birth by the Cult of the Kobra God, since a prophecy claimed he would lead them to rule the world.

In subsequent years, Kobra would clash with assorted superheroes, including Batman, whom he first met over a Lazarus Pit of his own creation.

Kobra had learned to build modified Lazarus Pits, which allowed him to control the minds of those he killed and resurrected.

Kobra had special concerns about Wonder Woman and sought to ensure her death, first by hiring a cartel of international assassins who were led secretly by corrupted UN Crisis Bureau chief Morgan Tracy (also Diana Prince's boss), then by kidnapping and irretrievably damaging environmental activist Deborah Demaine, forcibly transforming her into a new Cheetah, and ultimately, facing Wonder Woman in combat in Egypt, faking his own demise after being defeated by the Amazon Princess.

Kobra also fought the third Flash, the Suicide Squad led by Amanda Waller, the original incarnation of Checkmate, Captain Atom, a Superman whose personality had been swapped with Ambush Bug's by exposure to Red Kryptonite, and others.

In the Power Company: Sapphire #1 the Justice League rushes to San Diego to prevent disaster as two rival factions of the Kobra Cult prepared to go to war.

However, in a demonstration of his power, he incidentally kills Terri Rothstein, Atom Smasher's mother, ensuring the Justice Society of America's involvement.

Mrs. Rothstein's life would later be saved through time travel; Atom Smasher replacing her with the villain Extant so that the same number of people died in the plane crash that killed his mother.

Holding everyone hostage with this tactic, he was allowed by the JSA to escape, leading to an outraged Black Adam and Atom Smasher, who both subsequently choose to leave the team.

In JSA #51, Atom Smasher, Black Adam, Northwind, and Brainwave track Kobra down to his headquarters in the Himalaya Mountains, Kobra's prophesied 'reign of darkness' as the world fell to the return of Eclipso and Obsidian having ended when Alex Montez took control of Eclipso and Alan Scott managed to redeem Obsidian.

[11][12] When the Suicide Squad rescues Katana from Lady Eve, they find King Kobra outside Castle Markov.

[13] Kobra and Helga Jace later work together to fuse Violet Harper with he Aurakles energy being, transforming her into Halo.

[17] The Jeffrey Burr incarnation of Kobra appears in Batman: Soul of the Dragon, voiced by Josh Keaton.

After his forces are defeated by Lady Shiva, Richard Dragon, Ben Turner, and Batman, they plead with a desperate Burr to reject Kobra.
