Little is known about the Naljian species. They inhabit an upper position of existence.
Naljians are large, standing, semi-humanoids made of bright-white light that appear to have an aura of fiery blue flames around them.
Powers and Abilities
Naljians can teleport across deminsions in a flash of light. They can also use telekinesis, as shown when one of them could levitate and reform a Naljian Destructor with hand gestures alone.
Naljians can easily live for millions of years.
Naljians are apparently able to see in more than three dimensions as the one that spoke to Ben said that there were "only 26 (dimensions) that matter."
- Although String theory predicts only 10 dimensions, and the Standard model predicts 4, the Naljian who appeared in the series said there are "only 26 that matter", indicating that both theories are wrong in the Ben 10 universe. However, Bosonic String theory (the original version of string theory) predicts 26 dimensions.
