On the DC side, I know that Deathstroke has a pretty weak healing factor. There is another guy, known as Vandal Savage, and he is presumably "immortal", but from what I've seen, his healing factor is barely better than Deathstroke's. However, Vandal Savage is known to not be able age (in the comics, he hasn't aged in millienias).
