energisoid
Energisoid is a fictional energy-based lifeform that appears in the animated television series Transformers: Energon. These beings are composed of pure energy and are distinct from the mechanical Autobots and Decepticons, although they can interact with and influence them. Energisoids are often depicted as having a form of sentience and can communicate, though their methods of communication may differ from spoken language. Their primary characteristic is their connection to a substance known as Energon, the fuel source for Transformers. Energisoids are believed to be either creators of, or intrinsically linked to, Energon itself. Their presence often signifies a significant source of Energon or a point of instability related to its distribution. While not typically engaged in direct combat, Energisoids can exhibit immense power, capable of either aiding or hindering the Transformers depending on their disposition or external influences. Their motivations and origins are often shrouded in mystery within the series, serving as a powerful, albeit enigmatic, force.
