Idk who ever zoro saw but its definitely came from the mink’s medicine! Because of the mink’s medicine His body probably in its beyond its limits that Zoro is as good as dead by now! Even chopper and franky is hella worried.. so heres my theory!
if Zoro made this death guy obey him, or conquer this death guy then zoro probably will get a lot stronger body, his strenght, agility, instinct, haki and everything else that he uses would go beyond than before! This is similar to nen on hxh when a character dies and comes back alive they gained a huge boost power
this thing that zoro experiencing right now probably mihawk also experienced it and made a hugeeee boost in his overall capabilities! This is also probably experienced by reyleigh himself thats why he was called the dark king… because he conquered it?Who knows right?
in fact this death guy grim reaper thing if somehow zoro conquered him literally conquered death could probably heal his body! And he might deal with the ciper pol by himself or eveb hold off kaido if luffy needs another 10 mins to regain his haki.
