Stand reminds me of the Hanged Man. Arm blade and probably some kind of a mobility gimmick, like being able to move to blind spots, corners or shadows.
Finally, this may be the final main enemy. 89 years old means the head doctor may be born in 1923. I guess he is the grandson of Johnny Joestar, the father of Holy Joestar. Maybe this the Josef Joestar in SBR universe.

I couldn't stand the week-long wait for more Part 5 episodes so I started reading jojolion as well, this is the first chapter I've been fully caught-up for and read as it's released, and it's so exciting to see a stand that I didn't already know about through spoilers or wiki-diving
Given how the Rock Humans seem to be an alternate version of the Pillar Men, could this be an alternate version of Kars? The old man DOES seem to have some Stand ability related to time.
I think we can all agree that this is the SBR version of Diavolo. I bet that yasuho ex is probably doppio and the old man figure resembles silver chariot requeim
