Ah, yes, the best, most memorable bosses of the Persona series: Takahisa Kandori/Guido Sardenia, Pandora, Adolf Hitler, Nyarlathotep, Nyx, Erebus, Izanami... and... the subway slammer guy.
(I still haven't played Persona 5 Royal at all, yet, and I probably never will, because it is still, to this day, infested with Denuvo, and probably will remain so forever, because it was one of the games that, unfortunately, got in on the whole Denuvo thing back when Irdeto was still handing out lifetime licenses, rather than yearly subscriptions.)
