Do you deem any soulslike boss unfit for their respective game you fight them in? Where would you move them to?

Classic example is the depicted Demon of Hatred from Sekiro. Don't get me wrong - the fight does work in Sekiro. But it would feel at home in something like Bloodborne, at least that's what most fans say.

Is there any other boss you've encountered where you thought they'd fit a different soulslike better?
