Kryptonian

The Kryptonians are an endangered Humanoid race from the planet.

About
Kryptonians age much slower than Humans and live very long lifespans. In the Kingdom Come timeline of the DC Universe, Superman is shown to live over a thousand years, but it may be because of the Yellow Sun's enhancement of him. Kryptonians gain super powers when they are exposed to Earth's Yellow Sun, which gives them such abilities as flight, X-Ray vision, and freeze breath. They are also weakened by Kryptonite, radioactive rocks from the remains of Planet Krypton. There are several kinds of Kryptonite and each causes different effects.

Kryptonians are known to practice a variety of martial arts, an ancient combat style called Torquasm Vo (similar to Kung Fu), a meditation art called Torquasm Rao (which allows you to focus your chi), and an art called Klurkor (similar to Karate).

The Kryptonian language, also called Kryptonese, has an alphabet of 118 characters. In the movie Superman/Batman Apocalypse, Kryptonian sounds like a mix of Esperanto, a language based off of Latin, Greek, and Germanic languages, and gibberish.

Kryptonians were also known to have kept dogs as pets like Humans do. They lived in advanced societies with governments and councils.

Fall of the Kryptonian Race
Krypton was doomed. Before the planet exploded, the scientist Jor-El and his wife Tara, sent their infant son, Kal-El, into space. Kal-El, the last of his kind, landed on Earth in Smallville, Kansas, United States and was raised by a kind farmer, Jonathan Kent, and his wife, Martha Kent. They named him "Clark Kent". As Clark grew up, he discovered his true heritage and that he had super powers. He used his powers for good and became Superman, the savior of Metropolis.

Of course, there were other survivors too. The evil Kryptonian, Dru-Zod, better known as General Zod, survived. A fragment of Krypton survived in space, and that was where Kara-El (who would later be Supergirl), the cousin of Kal-El, was raised. Kara-El was sent to Earth as well, before the fragment of Krypton exploded.
