THE SECRETS OF MUMM-RA REVEALED! Mumm-Ra the Ever-Living has been a sinister enigma to the ThunderCats ever since they first set foot on Third Earth. Now, in the second chapter of author DECLAN SHALVEY’s epic 15-part ThunderCats X SilverHawks crossover event, the infamous devil-priest’s ancient and tortured history will finally be unveiled! It all begins in a pyramid — but not the sinister black fortress that haunts Lion-O’s dreams. This is Earth during the reign of the pharaohs, and for one nameless slave a chance discovery and a selfish act of cruelty will open a pathway to both freedom and power — for a price!
