Does the venerable Doctor D need to be retired? I would say no. The idea being posed that his history with the Nazi's is no longer relevant to modern times. This is a false assumption in my opinion but if we assume that he is "dated" then who exactly would you have take his place? What backstory of a super villain would we use that conveys such a simple evilness on a grand scale? As mentioned earlier, Dr D wasn't really a Nazi himself and if the whole Nazi thing is the issue, then just downplay it or outright change his history to fit your needs. Most, if not all, comic universes have a few big badguys that defy time itself through various methods. These very villains really shouldn't be facing off directly with player characters in my mind given their power level is just about off the charts. Obviously, there are exception to that but on the whole I find it to be relatively true. Dr. D. is the quintessential badguy in the generic champions universe. Should he be retired? Naah, just come up with something that fits your needs for your particular game. Whether this be his suit slowing his age rate, he takes cryo power naps to slow his age, moves his consciousness to a robot or someone else assumes his name after he has died. It's in your hands as the GM to decide what the needs are for your campaign.
