Zebulon is a planet that is far off in the universe. It is the home planet of all of the Zebulonian people such as Captain Hero. It first appeared in the episode Little Orphan Hero where it was also destroyed but was seen again, perfectly in-tact in subsequent episodes. It is a parody on Krypton.
Zebulon is a huge, purple planet that looks similar to Earth itself. The oceans are a purple color and the land is comprised of shades of magenta and pink. There are also white altostratus clouds that surround the planet.
