In the series, it was implied he'd been hopping bodies the same way that Dante has been, though probably not at the speed she was, but all the Hoenheims that I know of through the Nexus paid the price for bringing back Brian with his mortality, so his body doesn't degenerate or age anymore. But I don't know if he still has some of that rot on him or not."
