Declan Mason is just an average guy who is about to pop the question to the woman he loves more than anything when his whole world gets turned upside down.  No, that's not right, it gets crushed, pulped, eviscerated, and apocalypsed to hell before he even realizes what is happening.  He suddenly finds himself working for an Extradimensional Entity that has tasked him with committing genocide on a daily basis.  As Declan's new job, it seems, consists solely of him eliminating alternate versions of his Earth.  Not content to just destroy, he vows to save the woman he loves one planet at a time.  Soon, he's up to his armpits in doppelgangers of his dearie, and he starts to get a clue as to why he has to destroy each world.  Just to complicate matters the Horseman, the person who held his station prior to Declan taking over, has decided it is up to him to stop the Entity's murder spree and has placed Declan in his cross-hairs.        Apocalypse on Endless Earth's is seriously silly and actively adventurous.  Can one man learn to destroy numerous worlds in new and creative ways while simultaneously saving copies of the woman he loves?  Find out!
