WARNING: The following article contains spoilers for this week’s episode of Krypton, “Hope,” which aired Wednesday on Syfy.
Although it was obvious Jax-Ur, the enigmatic leader of the terrorist group Black Zero, was playing a long game on Krypton, her goals weren't clear -- beyond overthrowing the guild class and returning Kandor to the people, that is. She agreed to help Seg-El and his allies, but only if they would turn over magistrate Daron-Vex to her, not to settle an old score -- well, not exclusively -- but to learn how her old scientific work had been corrupted. She got what she wanted, and in this week's episode, "Hope," she used Daron-Vex's manual override code to access the Genesis Chamber and find out.
But while the secret hidden within the tower -- the cloned bodies of the most elite ranked houses -- likely sets up a plot line for Krypton's second season, it's the override code is what undoubtedly drew the attention of longtime DC comics fans. Specifically, the second word: Flamebird.
It's the identity adopted by Jimmy Olsen in the Silver Age when he and Superman operated as costumed vigilantes in the bottle city of Kandor. Through a misunderstanding, the Man of Steel was branded an outlaw and, therefore, became Nightwing, and Jimmy his sidekick Flamebird. Both names were later used by other superheroes, of course.
However, Jax-Ur's code isn't a reference to the superhero, but rather the Kryptonian animal that inspired Flamebird's name. In fact, all the words in the override code are Kryptonian flora and fauna: The first word, hantha, is a fragrant yellow tree; flamebird is a red-and-yellow bird sacred to the priest of Rao; rokan is a pterodactyl-like prehistoric bird; and oregus is a plant whose juice is used in cooking. It's unclear in the numbers "29718" have any special significance.
So, yes, the key to accessing the greatest secrets of Kandor's elite is a rundown of obscure Kryptonian plants and animals from DC comics -- plus, a creature from an episode of Super Friends.
