Naljian

Little is known about the Naljian species. They inhabit an upper position of existence.

The Naljians are large standing, semi-humanoids made of bright-white light who appear to have a blue flame around them.

The Naljians are extremely advanced in technology and possess superior intelligence, even more than the Galvan, as their children's toy could easily surpass the alien tech level (Level 20+) with the Omnitrix being Level 20.

Their life span seems to be extremely high as a being of 3 million years is considered a mere child by their standards.

Powers and Abilities
Naljians can teleport and they can use telekinesis. Naljians can easily live for millions of years. They are also apparently able to see in more than three dimensions as the one that spoke to Benjamin Tennyson said that there were "only 26 (dimensions) that matter", which means they may be come from 26th Dimensional
