History:
 Krypto was the family dog in Jor-El's household, and was used for a test flight of the rocket that eventually carried baby Kal-El to Earth. However, Krypto's rocket was blown off course and drifted in space for many years until the rocket picked up the signal from Kal-El's rocket that landed on Earth. Krypto arrived when Kal-El was a teenager, and the two got along famously. Krypto adventured alongside young Kal-El, though he was not publicly known. This new version of Krypto had superhuman (or, supercanine) abilities, but with a normal canine intellect. This initially caused a great deal of trouble for his new master. For instance, Krypto would scratch at a door to indicate he wanted to go out and unintentionally gouge big chunks out of the door with his super-strength or inflict grevious bodily harm when combating villains (since Krypto bites the way a regular canine would, only without being careful about his super-strength). As a result, Krypto was for some time locked away in the Fortress of Solitude under the care of one of Superman's robots programmed to emit the scent of the dog's real master. Superman has gone to great lengths to train the dog, and Krypto has occasionally accompanied the Man of Steel on missions. Batman never misses an opportunity to poke fun at Krypto when Batman and Superman don't see eye-to-eye.  Krypto had a surprisingly violent reaction to Kara Zor-El when he first encountered her. The dog happened upon the girl while she was exploring the Fortress of Solitude. Krypto attacked, going so far as to use his heat vision and other potentially lethal attacks.  Some time later, Superman left Krypto in Superboy's care, saying that Smallville's open spaces were a better place for the dog, and that Superboy could use a friend.[1] Their relationship had a shaky start, not helped by Krypto getting Superboy in trouble with the superheroine Starfire for destroying her alien garden.  However, they slowly developed a close friendship in which Krypto willingly did anything he could to protect Conner. One example of this loyalty was Krypto's quick defense of Conner from an outraged Superboy-Prime. Although Krypto was injured, this only strengthened his relationship with Conner.  With the murder of Conner by Superboy-Prime during the Infinite Crisis, Krypto has been taken by Superman to his retreat at the Fortress of Solitude where the sole remaining Earth-made Superman Robot now called "Ned" watches over and plays with Krypto.  Krypto was left with Martha Kent in the wake of Jon Kent's death, and is playing around in Smallville with Conner Kent in the wake of his resurrection. Most recently, Krypto joins Superman and Conner in a battle against the Black Lantern Superman (Kal-L). The battle sheds insight into Krypto's emotions in-battle, where he is awash with love, rage and will.

Powers:
  Krypto's cellular structure is more dense, resilient and biologically more effective than canine tissue. As an alien animal he possess several organs whose functions are not yet disclosed or understood but are believed to be part of and perhaps even the source of his biomatrix force field and reclamation aura. Krypto's body also stores energy actively within his bio-cellular matrix as an energy pattern that is linked to his body's electromagnetic field. This energy powers most of Krypto's electromagnetic capabilities such as flight and heat vision senses of smell and hearing) would be more acute than those of Superman, just as an ordinary dog's senses would be more acute than those of an ordinary human. Krypto also had super-canine intelligence (approximately human level, though with his canine traits and interests still present)   Technically, this is the main source of Krypto's powers. Because Krypto's powers are greatly due to exposure to Earth's yellow sun, his powers have been affected by extreme absorptions of solar power, whether voluntary or involuntary.   He is incredibly strong and can lift 100 tons, with no effort. He can lift a tree in his teeth and caused Superboy-Prime intense pain and injured his shoulder by biting him.   He has survived punches from Superboy-Prime.   His stamina is many times greater than any human or animal's stamina. Flight: He can fly at incredible speeds that are easily supersonic.   His top speeds are unknown but are easily supersonic.   The ability to create hurricane force winds by blowing, and to chill his breath in order to freeze a target (this latter ability has also been called "freeze breath" and "arctic breath"). Exhaled through his bark.   The ability to hear any sound at any volume or pitch. The only Earth creature who can detect sounds at the frequency he can is a blue whale (0.01-200,000 Hz). He has shown enough control to block out ambient sounds to focus on a specific source/frequency. He can identify a person by their heartbeat, or pick out a single voice in an entire city.   The ability to fire beams of intense heat at a target by looking at it with the conscious act of activating this power. Visually, the power is typically depicted as two beams of red light firing from his eyes.   He also possess a superior sensory arrangement of microscopic, telescopic, infrared and ultraviolet visual capabilities. Abilities include:   He can see well into most of the EM Spectrum. He can see and identify radio/television and any and all broadcast/transmitted frequencies, allowing him to avoid detection through radar or satellite monitoring methods.   The ability to "zoom in" his distance to see something at a great distance.   The ability to see through anything except lead. He can see things behind a wall as if the wall were not there, or can "peel back" layer after layer of matter in his mind. Since it is passive, this ability would not generate harmful radiation in the same manner as a focused projection of hard X-rays.   The ability to see extremely small objects and images down to the atomic level (normal optical microscopes can only see objects down to the size of chromosomes).
