Citizens: Kara Zor-El, Kal-El, Alura Zor-El, Zor-El, Astra, Non.
First appeared in: Supergirl: ‘Pilot’.
Notes: The home world of Superman and Supergirl was once a great and cultured civilisation, among its most celebrated families was the House of El. However, the planet was destroyed due to its natural minerals and resources being mined to a disastrous extent. The only known survivors of the planet’s destruction were the two El cousins and Kara’s aunt and uncle, Astra and Non. It is unknown if General Zod and his followers escaped in this continuity.
Citizens: Mon-El, King Lar Gand, Queen Rhea.
First appeared in: Supergirl: ‘Survivors’.
Notes: Despite being the sister planet of Krypton, Daxamites and Kryptonians had a fierce rivalry due to their different opinions on issues such as slavery. The society was oppressive but an uprising never happened due to the ‘party culture’ enforced by the royal family. Daxam was destroyed in a meteor shower of Krypton’s irradiated fragments.
First appeared in: Supergirl: ‘Supergirl Lives’.
Notes: AKA Slaver’s Moon, Maaldoria is the slavery capital of the galaxy. Roulette allied herself with the Maaldorians to start a covert human slavery racket. When Supergirl travelled to the planet to stop her, she discovered that it orbited a red sun – possibly Rao, the same sun Krypton once orbited – thus negating her powers.
First mentioned in: Legends of Tomorrow: ‘Destiny’.
Notes: The alignment of Earth and Thanagar caused a meteor to crash into Ancient Egypt, thereby granting Hawkman, Hawkgirl and Vandal Savage immortality. The Time Masters later allied with Savage in a bid to avert a future where Thanagarians invaded Earth. Like the Dominators, the Thanagarians are known to exist in both Earth-1 and Earth-38.
