Years ago, Siamese twin brothers were born to the Burrs, American's vacationing in New Delhi, India. After a lengthy operation, the brothers were separated, and the family were informed that one of the twins had died in the maternity ward. Unknown to the family, the boy they thought dead had actually been kidnapped by a cult of fanatical Cobra worshipers, who believed the child to be their chosen leader.
The Jeffery Burr version of Kobra was created by Martin Pasko, Steve Sherman, Jack Kirby, and Pablo Marcos. The later version with Jason Burr as Kobra was created by Ivan Brandon and Julian Lopez.
Raising the child to assume the role of leader of the Kobra cult, the cultists trained him in almost every martial art. To both the child's and his brother's chagrin, however, they discovered that they were biologically and psychically linked. When one brother felt pain, so did the other. It was not until after the kidnapped youth had grown to maturity and was calling himself Kobra, that the other twin, Jason Burr, discovered his twin still lived.
Jason was enlisted by the authorities in a vain attempt to stop Kobra and was ultimately murdered by his brother with the aid of a "neural neutralizer," which temporarily severed the psychic link between them.
Without his brother to hold him in check, Kobra became a notorious megalomaniac hoping to conquer the world.
Batman once said that Kobra was the 'second most dangerous man' he'd ever met (after Ra's al Ghul).
Jeffrey kidnaps the hero Air Wave in order to seize control over the world's communication systems and destroy several major cities. He causes a plane to crash, killing 217 people, including the mother of Atom Smasher (although time-travel saved her later). After he is captured he is put on trial for his crimes. He and his followers manage to hold the courthouse hostage and the JSA allows him to go free. Disgusted by this Black Adam and Atom Smasher track him down and Black Adam rips his heart out.
Years later Jeffrey's brother Jason is brought back to life by the Kobra cult to serve as their new leader. Despite his past resistance to the cult in the past, Jason gives in to his role, killing many Checkmate agents and deciding to kill off all the remaining Kobra member in order to restructure the organization. He then wages war against the Justice Society of America.

Batman Beyond: The Rise and Fall of Kobra
In the future, Dr. Abel Cuvier was the chief geneticist of the terrorist organization, Kobra. He genetically designed a test tube baby named Zander to be the future leader of Kobra. Dr. Cuvier's mission was to initiate Kobra's master plan which is dominating the entire world. However, Cuvier took Kobra's plan in a different direction by manipulating the future generations of the world with his splicing technology. Splicing started as a fad but now it has evolved into a lifestyle.
However, Bruce has discovered peculiar irregularities in the splicing process. For instance, an individual eventually loses their ability to speak coherently and their human characteristics succumb to animal instincts. After a while, the splicing process destroys the individual's moral sense of humanity and obliterates their control over their animalistic impulses. D.A. Sam Young begins his campaign to pass anti-splicing ordinances against the splicing movement. Young also enlists the help of gene therapist Dr. Maria Liam. Liam's work could be used to improve or adapt the splicing serum or it can be used in gene extraction.
