Perhaps the only thing more terrifying than a Battle Titan is a Chaos Battle Titan, the infamous metal leviathans of the arch-enemy. Some are manufactured in the smithies and forges of the warp, their designs copied and parodied from the Imperial originals, sacrilegious perversions of the Martian god-machines. Others are ancient Imperial Titans corrupted during the Great Heresy, traitor legions that have lurked in the Eye of Terror for ten thousand years in defiance of the Emperor’s will.
