Doctor Who: The Lost Dimension is an epic event comprised of eight chapters crossing over all four-ongoing series (Ninth, Tenth, Eleventh, and Twelfth Doctor comics).

The event will begin a new era for Titan's Doctor Who comics, and will find the Ninth, Tenth, Eleventh, and Twelfth Doctor playing their part to battle The Void!

The Void has always existed: "No place. The silent realm. The lost dimension." But the Void is no longer empty. The Void is hungry, and devouring our universe through time and space. Now, the four Doctors must join forces to save... everything!
