Kryptonian

Kryptonian is a fictional humanoid species from the planet Krypton in DC Comics. They are typically portrayed as highly advanced, technologically adept, and scientifically minded. Krypton is commonly depicted as a flourishing civilization that is ultimately destroyed, with some formulations centering on the House of El as a notable lineage.

Biology: Kryptonians resemble humans but are often depicted as robust and long-lived. In many depictions, exposure to a yellow sun grants Kryptonians superhuman powers such as strength, speed, flight, and invulnerability, while red solar radiation or kryptonite can weaken or harm them.

Culture and society: Kryptonian society emphasizes science, governance, and education. Notable figures include Jor-El, a leading scientist who warned of Krypton's impending doom. The planet's destruction is a recurring element in modern retellings, sending survivors to other worlds, most famously Kal-El, who becomes Superman.

Language: Kryptonian refers also to the language and script associated with Krypton, portrayed as a distinct symbolic writing system in various comics and media.

In popular culture: Kryptonians appear across comics, films, and television within the Superman mythos, contributing to their status as one of the best-known fictional civilizations.
