Nexus Omnibus v02 (2013)

Plagued by nightmares of the horrific misdeeds of his mass-murderer targets, the executioner Nexus chooses a life-threatening procedure to block his tormenting night visions. But though the nightmares cease, the behavior of Nexus becomes increasingly erratic and violent, a dangerous development for a man who wields the power of the stars! Collects Nexus #12–#25.
Nexus has won six Eisner Awards.
Look for new Nexus in Dark Horse Presents!
