Naljian

Little is known about the Naljian species.

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

Abilities
Their abilities are largely unknown, but it is shown that they are extra-dimensional beings who have incredible power, almost like the Celestialsapien species. They can use telekinesis. Also, from what the Naljian, who retrieved the Naljian Destructor, said a Naljian can easily live for millions of years, because she said the Naljian Destructor was clearly labeled "not for children under three million years old". They are also 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".

The Naljians are extremely advanced in technology, even more than the Galvan, as a children's toy could easily surpass the alien tech level (20+) with the Omnitrix/Ultimatrix being the maximum level 20.
