Davros first appeared in Doctor Who in 1975 as the creator of the Daleks, and the Reality Bomb storyline returned in the 2008 finale The Stolen Earth and Journey's End. In that story the weapon was designed to cancel out reality across every universe, giving Davros his most extreme scheme. Clips of his speeches circulate among fans for quoting, remixing and parody, with this moment kept alive because the threat is so vast it works equally well as genuine sci-fi drama and as an over the top reaction to everyday disasters online.
