Drej

The Drej are the antagonists of Titan A.E. 2025. They are an alien species, made of pure energy.

Appearance
Upon first inspection, the Drej seem not much different from our species. They're not corporeal entities, yet they have a physical form which appears to be both skeletial and humanoid.

All Drej are made, as Korso claims, entirely out of pure energy, giving them a bright blue glow. At the front of their heads is what appears to be an eyespot, which, according to the novelization, also houses a mouth, the latter of which is not seen in the film. Despite their physiology, however, they are tangible and can manipulate objects just as easily as other sapient races. Furthermore, when a limb is destroyed they can regenerate it in a matter of seconds, possibly by extracting energy from their surrounding environment. Drej can fire portions of their substance at foes in a concentrated blast, although whether or not this expendature of energy subsequently weakens their physical form is not explained.
