The Residents of the Land of Light, or the People of Nebula M78, also known as Ultras, are the race who live on the Land of Light. They are beings of light who are known for their great powers and strong sense of compassion and justice, which motivates them to promote peace across the universe.

An Ultra's average height is usually 130-160 feet (40-50 meters). Ultras have various abilities, most notably their ability to manipulate energy. They are able to fire energy beams from various positions of crossed hands, levitate objects, and create barriers. Ultras are able to fly and have displayed the ability to heal other beings through their light.

Since the Earth's atmosphere naturally filters out most of the light that hits it, an Ultra's energy supply is limited while they are on Earth. Some Ultra shows state the problem is that the Earth's atmosphere is too badly polluted to allow enough light through. Ultras do not have time limits in space or on planets lacking an Earth-like atmosphere.
