Under a yellow sun, he shares the powers of Kryptonians: DC lists super strength, flight, invulnerability, super speed, heat vision, freeze breath, x-ray vision, superhuman hearing and a healing factor.

Who is Krypto?
DC describes Krypto as a loyal canine companion and friend to the entire Superman family. He is Kryptonian, not an ordinary Earth dog, and his abilities are connected to Kryptonian biology beneath a yellow sun. DC’s character profile gives a concise overview of his place in Superman’s world and his powers.
Krypto first appeared in Adventure Comics #210, published in 1955, according to DC’s profile. DC Comics Collection dates that issue to March 2, 1955. DC character profile · DC Comics Collection
Krypto’s backstory depends on the story
There is not one origin account that applies to every version of Krypto. DC’s general profile says he was among the few animals to survive Krypton’s destruction and found his way to Earth years after Superman. A newer comic tells a more specific story: it begins with Krypto as a puppy on Krypton with Jor-El, Lara and baby Kal-El. A rocket test goes wrong, leaving him lost in space before he crash-lands on Earth. That is the premise of this particular story, rather than a universal explanation of his history.

Where Krypto fits in recent screen adaptations
Krypto also appears in the current Superman screen context, but film descriptions should not be treated as a replacement for comic-book origin accounts. The official Superman site names James Gunn as director and gives the theatrical release as July 11, 2025, in the U.S. and July 9 internationally. Official Superman site
The official Supergirl site dates that film’s release to June 26, 2026, in North America and June 24 internationally. Its description says Kara joins an unlikely companion on an interstellar journey. As of October 7, 2026, the site labels the film available on digital and advertises 4K, Blu-ray and DVD. Those details establish release and home-viewing context, not a fuller account of Krypto’s role or a particular streaming-service availability. Official Supergirl site
