Mad Methodical Masterminds and Their Twin Brothers

Truly tortured souls were these pairs of tormented twins. There was Jason Burr of Earth-One and his long long twin Jeffrey. Then there was Douglas Strange of Earth-Two and his long lost twin brother, Rodney Strange. Both dynamic duos had difficult relationships given the circumstances in their early lives and their later decisions.

On the surface, they seemed to have unlimited potential... Jason was recruited into an international investigative agency. However, this was because Jeffrey had been kidnapped as a baby and raised by the sinister Kobra Cult to become their future leader. As Kobra, Jeffrey was a mastermind with resources in both manpower, technology and physical training to be at the peak of human perfection.

Doug Strange was imprisoned for five years, as he was mistaken for his twin Rod who as a youth had been kidnapped by the evil Sin Chow and turned into a megalomaniac mastermind. Once freed, Doug joined Scotland Yard and trained as a master detective, with a goal of pursuing his sibling Rod who was known as Chinese warlord pirate. Both of the wayward twins had vast organizations they led versus their heroic twins and their allies in law enforcement.

While Kobra faced Batman and other members of the Justice League of America, Strange never interacted with the Justice Society although they were chronicled contemporaries of mystery men Neon the Unknown and Red Bee, both of whom were members of Earth-Two's Freedom Fighters.

Eventually, there was an end to the hostility between both pairs of twins. For the Burr twins, this happened when Kobra manipulated the mind of Jason's girlfriend into killing him. For the Strange twins, it happened when Douglas convinced Rodney for forsake his criminal ways and join him in combating injustice. There were counterparts to the Burrs and Stranges on Earth-S in the so-called "Jungle Twins", of whom William Dale was raised in New York while his twin brother Steven survived in Africa where the pair's parents had been killed. Although initially adversarial, the twins eventually mended fences.

Interestingly, on Earth-Two there was a villain known as the Black Cobra, or by the alias of "Naja Hana", This Naja Hana faced aerial ace Hop Harrigan on a couple of occasions, wearing a bright orange bodysuit with a green robe atop... nearly identical to that worn by Naga Hana the Kobra. Both had a vindictive nature and amazing far-eastern abilities.

Naja Hana was the Earth-Two version of Earth-One's Randu Singh, who was also an Indian like Hana only good instead of evil. However, Naja's alter ego as the Cobra played the part of Naga Naga, the Kobra's more infamous moniker. And coincidentally, Kobra and Randu dueled once or twice themselves.
