Moon Knight battles new demons! When Marc Spector's serial-killer brother returns from the dead, can Moon Knight stop the Punisher from sending him back to the grave? And will Marc's upgraded suit withstand an encounter with Dr. Doom?! Then, as the Infinity War rages, Moon Knight faces a series of deadly doppelgangers! But all the while, something is very wrong with Marc - and it may be beyond even the minds of Mister Fantastic and Doctor Strange to save him! The clock is ticking, and all hope seems lost. To preserve his legacy, will he need to find another avatar for Khonshu? As one phase ends, a new one begins - because you can't keep Moon Knight down for long!
