Zhylaw, Lord Marshal (Chronicles of Riddick) vs Black Panther (MCU)
Victory by death, must be H2H-only.
Unlike the fight with Riddick, BP gets no outside help and must kill him in H2H combat, it goes both ways and the same is true for Zhylaw.
Round 1 - No necromonger superspeed, straight H2H fight, BP can't wear his mask, no vibranium claws.
Round 2 - Necromonger superspeed allowed, BP can wear his mask and has vibranium claws. (If you think this is unfair for Lord Marshal, then he's allowed to use his spear.)
