Oroborus
- You may be looking for the symbol or the TV story.
The Oroborus was a snake-like creature able to traverse dimensions and feed on time. It was also known as "the cosmic serpent". It could consume chunks of the timeline; the more it ate, the more it grew. It could shed its skin like real snakes. Once it was fully grown it could consume an Earth-sized planet in hours.
Some time before 2050, the Oroborus turned Centauri into a black hole by siphoning off its future. This event was known to Alistair Gryffen.
The Oroborus made its way to Earth through Gryffen's Space-Time Manipulator and hid in Gryffen Manor's basement. It consumed time until Starkey discovered what was going on and lured it into the Manipulator's path, sending it away. (TV: Oroborus [+]Loading...["Oroborus (TV story)"])
During the Last Great Time War, the Codicil sought to use an Oroborus to end the conflict. When the War Doctor suffered a retro-regeneration crisis, the Codicil manipulated him into conflict with the Fugitive Doctor, the paradox of two incarnations fighting summoning an Oroborus. Realising they'd been duped, the Doctors used a time ram to banish the creature before it could grow in strength. (AUDIO: Coda - The Final Act [+]Loading...["Coda - The Final Act (audio story)"])
