Nukie's Species

This alien species is a form of energy-based lifeform that features in the 1987 film "Nukie". The individuals making up this alien race in said film are brothers Nukie, and Miko.

Biology
While appearing humanoid in physical shape when on Earth, they aren't considered biologically organic in nature as they don't possess most physical organs for bodily function; they don't possess lungs, nor brains, and presumably no digestive system. They are shown, however, to respond to pain when in a physical state, suggesting an active nervous system similar to organic lifeforms. This is limited however, as one was observed able to drink boiling water without showing signs of pain.

Although capable of remaining in their energy-based forms at will, they gain a materialistic form once they venture onto another planet outside of their home planet. In the case of earth, their physical form appears mostly humanoid or simian in nature: a bipedal form with hairless wrinkly skin, a ape-like face, and enlarged ears and eyes.

Abilities

 * Psychic Ability - the beings have shown a number of psychic-based abilities, mostly shown when communicating to their own kind. Amongst these includes Telepathy over vast distances vaguely similar to mechanical signals, and even memory projection to one another: a sleeping individual can observe memories of a secondary individual, even if never seeing some of the memories themselves prior.
 * Mechanical Possession - due to their bodies being made up of pure energy, these beings are capable of possessing mechanical structures and operate them with ease. This includes highly advances vehicles such as motorcycles.
 * Multi-lingual - this species is capable of understanding numerous known languages, albeit after concentration (at least in the case of Miko, one member of the alien species).
 * Physical Alteration - Alongside their own ability to alter from a physical form into their natural energy state, they are also capable of transforming other beings into a similar energy-based form, regardless of their biological makeup.
 * Invisibility - these beings are capable of turning themselves invisible and incapable of being touched, possibly due again to their bodies naturally being made of energy. While it can be done at will, they naturally turn invisible when resting, making them incapable of being detected even by satellite.
 * Pyrokinesis - These beings, while observed briefly, have been shown to heat up materials to the point of burning.
