The natives of the Planet U40 in what is called the Joneus universe/continuity by fans of the Ultra Series. The people of U40 are a race of Ultras with their planet serving as that universe's equivalent to the Land of Light. The people hailing from the planet U40, originally they were a race of beings almost identical in appearance to the people of Earth.
At some point in time they cam across an energy known as the Ultra Mind with which they bonded with becoming the Ultramen. The first major difference between the people of U40 and the Residents of the Land of Light is that among the U40 Ultras only eight are known to change their size.
