The Taelons are an alien species from another galaxy in Earth: Final Conflict. Though the Taelons can take physical form, they are beings of energy.
They are genderless and known to not express their emotions through facial or vocal tones.
Taelons assumed a human "facade", where they assumed a skin tone and ears. When not in this form, they appeared as glowing blue and red veins surrounded by a transparent humanoid shell.
Taelons were also known for their advanced biotechnology. The most common examples were living ships employed by the Taelons, as well as Skrills used by Companion protectors. In addition, the Taelons could 'grow' their buildings. The Taelon headquarters as Washington, D.C, appeared organic, and the building housing William Boone's office had the appearance of a creature attached to a human building.
