Synopsis:
Prior to Krypton's destruction Brainiac visits the planet. Instead of shrinking Kandor, Brainiac shrinks Kryptonopolis, the home city of Jor-El. Brainiac does so to save the city from Krypton's destruction and is hailed as a hero. However, Brainiac is unable to enlarge the city back to normal size, so the residents remain trapped in the bottle for many years. During that time Jor-El and Lara have another son, Knor-El.

Years later, Brainiac finally discovers a way to enlarge the city. However, a tragic accident occurs, killing Brainiac and leaving the bottled city abandoned on Earth. Enough of Brainiac's rare elements still exist to enlarge one man, so citizens compete for the honor of becoming Earth's Superman. Knor-El wins with Kal-El finishing second.

Knor-El is enlarged to full size and adopts the secret identity as Ken Clarkson, reporter for the Daily Planet. He fights crime and builds an undersea lair to protect the bottled city. When aliens invade and hit Knor-El with Kryptonite, Kal-El uses an experimental method to enlarge himself and save his brother. Together the brothers stop the invasion.

After the battle Knor-El continues to fight crime as Superman. Kal-El also remains at full size and becomes the Canadian hero Hyperman.
