Hyperion (species)

The Hyperions were a race of sentient suns.

Biology
The Hyperions were a fusion of DNA, nuclear energy and hyper-intelligence. Their evolution was akin to that of suns. The final stage made them burn up, the energies within them mutating out of control, leaving the entire species on the verge of supernova. (COMIC: Terrorformer)

History
The Hyperions left their homeworld on a quest to enlighten the lesser races of the universe, to make it a better place.

At the last stage of their evolution, the Hyperions turned from benevolence to malevolence. They began to subjugate various species, including those whose civilisations they had helped create. The Hyperions would encircle the suns with a fusion-web and drain them from their sustenance to prolong their own existence.

The Time Lords, Silurians, Sontarans and other races formed the Alliance of Races to stop the Hyperions, and declared war. The war wiped out most of the Hyperions.

The Twelfth Doctor encountered a survivor of the war, Rann-Korr, on Isen VI. (COMIC: Terrorformer)
