Egron


 * For the creation of Omega, see Ergon.

Egron (also known as Egron the Flesh-Eater) was a shape-shifting fugitive hunted down by law-enforcement mechanoid DRC-1000, who adopted the form of the TARDIS and trapped Amy Pond within, threatening to digest her. The Eleventh Doctor overcame Egron with foul smelling fungi abundant on the planet of capture and Amy was vomited up. (DWAM: Mistaken Identity)
