Nightmare Child
From Tardis Wiki, the free Doctor Who reference
Nightmare Child was a phenomenon that was extant during the first year of the Time War. Davros' command ship flew into the "jaws" of the Child. Despite the war being Time locked, Dalek Caan managed to enter the war with an emergency temporal shift. (DW: Evolution of the Daleks) He arrived in the middle of the battle and saved Davros. (DW: The Stolen Earth)
