The Eternals’ bodily cells contain cosmic energy, and they maintain constant mental control over every molecule of their bodies. Eternals are virtually immortal, and can be restored to life even if the molecules of their bodies are scattered. All Eternals possess the capacity for superhuman strength, telepathy, flight, teleportation, illusion-casting, transmutation of organic and inorganic matter, and the generation of various forms of energy from their bodies, including force, heat, light, and other electromagnetic radiation. Some Eternals have devoted themselves to specializing in a particular facet of their powers, and can increase their proficiency in one area by decreasing their power in another. The Eternal who serves as Prime Eternal can generate blue flame that will merge anyone who passes through it into a Uni-Mind, a powerful psychic entity which embodies the collective power of every individual who created it. A Uni-Mind requires the participation of at least seven Eternals in order to succeed.
