Krypto the Superdog is a American animated television series produced by Warner Bros. Animation, based on the DC Comics character Krypto. The show premiered on Cartoon Network on March 25, 2005, and aired on Kids' WB in September 2006. It would usually air after the Tickle-U block.
A comic book series (based on the TV show) was published by DC Comics under the Johnny DC imprint, which lasted 6 issues, from 2005 to 2006. The show was designed primarily for young children. However, as a result of being aired (and cancelled) in the mid-2000s, it has made an imprint on the older child demographic as of 2012.
The show was produced in a manner reminiscent of the Hanna-Barbera shows of the 1960s to the 1980s, from the sound effects down to the animation style (veteran Hanna-Barbera designer Iwao Takamoto served as a creative consultant). The series is rated TV-Y.
The show was close captioned by the National Captioning Institute like many of Warner Bros. Animation's shows at the time.
The series aired on Boomerang from February 5, 2007 until December 31, 2013.
As the planet Krypton is about to be destroyed, Superman's father Jor-El makes a ship and puts a white puppy named Krypto into it for a test flight to see if it is safe enough for interstellar travel. While aboard the ship, Krypto accidentally destroys several wires and causes the ship to put him into a deep sleep while it heads on to Earth.
Upon landing on Earth, Krypto is a fully grown dog, possessed of superpowers similar to those of Superman's (since all Kryptonian life-forms gain superpowers from exposure to a yellow sun, such as Earth's sun). Later, Krypto is adopted by Kevin Whitney, a 9-year-old boy, with whom Superman arranges for him to stay (as Superman himself is often too busy saving the world to take care of him). Krypto poses as an ordinary dog while living with Kevin's family, but adopts the secret identity of Superdog for his superheroic deeds; Kevin is aware of Krypto's dual identity, but the rest of Kevin's family is not. (Excluding Kevin's spoiled cousin Bailey, however accidental).
In the series, the various animals, including Krypto, all are capable of speaking to each other, but not to humans, except for Kevin (who is able to communicate with Krypto and the other animals thanks to a universal translator Kevin wears, known as an intergalactic communicator).
