BLACK PANTHER (1998) #21

Guest-starring Moon Knight! Killmonger has defeated T’Challa in personal combat, which means he’s now the tribal leader of the Panther Clan, and entitled to wear the mantle of the Black Panther! Now, as our hero lies near death, only the power of Khonshu, embodied by his avatar the Moon Knight, can guide him through the realms of the dead and back to life!
