While Peter Capaldi's Twelfth Doctor is battling the universe's darkest forces on the small-screen, Doctors Nine, Ten and Eleven are also enveloped in their own adventures in the pages of Titan Comics' monthly Doctor Who series.

Well, those worlds are about to collide, as Titan has exclusively revealed to CBR the announcement of a new event, titled Doctor Who: The Lost Dimension, that will crossover multiple takes on the beloved time-traveling adventurer, originally brought to life by Christopher Eccleston, David Tennant, Matt Smith and Capaldi.

Set to tell its story in eight chapters over the course of three months, Doctor Who: The Lost Dimension kicks off with an Alpha issue written by Nick Abadzis (Tenth Doctor), George Mann (Eleventh Doctor) and Cavan Scott (Ninth Doctor), with art by Rachael Stott (Twelfth Doctor) and Rob Fernandes, set for release in August, ahead of the Doctor Who Comics Day global event scheduled for Saturday, September 2. The event will continue with Chapter 2 in the pages of Doctor Who: The Ninth Doctor the following week.

Teasing the series, Titan wrote in a statement, "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!"
