Hello, I'm an expert in comic book lore and superhero narratives. Let's dive into the question at hand.

Doomsday is a fictional character appearing in American comic books published by DC Comics, and is best known as the villain who kills Superman in a storyline that has since become one of the most famous in the publisher's history. However, Doomsday is not from Krypton. He was created by writer-artist Dan Jurgens, and he first appeared in Superman: The Dark Side #1 in 1992. Doomsday is an artificially created being, engineered through the use of Kryptonian technology, but he is not Kryptonian himself.

His origin is actually quite complex. Doomsday was created on the planet Krypton, but he was not a native species. He was designed as a tool of destruction, a creature meant to be so powerful and destructive that he could eliminate any threat. Doomsday was part of a series of experiments conducted by Kryptonian scientists to create the "ultimate life form." However, the creature became uncontrollable and was ultimately exiled from Krypton.

So, to answer your question directly: Doomsday is not from Krypton, but he was created there using Kryptonian technology.
