Chronovore

Chronovores are powerful, transcendental beings native to the Calabi-Yau Space. Chronovores are generally seen as pure-white humanoids with small wings and a helmet-like head, but they can easily change their shape. Chronovores have three main sources of sustenance. In general, they can feed on the natural energy of the Calabi-Yau Space, but this is dull and unappealing food. Chronovores can also eat the history of a humanoid, which annihilates them from existence (they especially like Time Lords). The Chronovores' favourite food is alternate dimensions, which they try to devour when they find. Because of this diet, the Chronovores were feared and hated by the other transcendental beings, especially the Eternals. (PDA: The Quantum Archangel)

The Chronovores were led by the Divine Host, a group of particularly dangerous Chronovores and Kronos, a Chronovore/Eternal hybrid. (PDA: The Quantum Archangel) The Chronovores were also both feared and worshipped, especially in Atlantis, which Kronos would later destroy. (DW: The Time Monster)
