The Cybus Cybermen were introduced in the revived Doctor Who in 2006, in the two-part story Rise of the Cybermen and The Age of Steel. Created on a parallel Earth by Cybus Industries founder John Lumic, this version converted humans as an upgrade and ordered enemies deleted. The harsh synthesised Delete delivery quickly separated them from the classic Cybermen from 1966. Clips of the line spread through fan edits and forums, and the sound stayed popular as a short, recognisable shorthand for cold, robotic elimination.
