The
capital city of
Krypton. Prior to the destruction of
the
planet, the
villain Brainiac shrunk the
city down
to microscopic size and put it in a
bottle, taking it with
him aboard his
spaceship. The city stayed in
Brainiac's
possession until he came into conflict with
Superman while
trying to perform the same act upon the city of
Metropolis.
Superman defeated Brainiac and rescued the tiny city, taking
it to his
Fortress of Solitude.
Superman was unsuccessful in finding a way to return the city
to normal size, but he was able to shrink himself to visit
the city. He maintained a Kryptonian gravity level for the
tiny city allowing the city and its inhabitants to live a
relatively normal life. The inhabitants of Kandor all know
about Superman being Clark Kent.
When Superman visits Kandor, he does not have superpowers,
but when on a visit there with Jimmy Olsen, the two created
costumed identities for themselves, so that they could fight
crime. As Nightwing and Flamebird, Superman and Olsen
fought crime in Kandor. Their base of operation while they
were in Kandor was the nightcave and they used rocket belts
to travel.
The reason that
Brainiac chose to shrink the city of Kandor
was never sufficiently explained. Whether it was for some
diabolical experiment or just a
Martha Stewart home
project just gone terribly wrong, we are left to wonder.
The other problematic issue of the Kandor stories is the
Kryptonian gravity bit. The fact that the gravity in Kandor
was such to make Superman act like a normal human should also
tell us that if Superman brought a normal human like Jimmy
Olsen to Kandor that Jimmy would be a red smear on the
pavement. But it pays not to think about these things too
much.
