8. Ra’s Al Ghul

(Batman, DC Comics)

Sometimes a character should stay dead, not because he’s a bad character, but because he’s been successfully replaced.

Ra's Al Ghul was killed during Death and the Maidens, a Batman arc that introduced his (other) daughter, Nyssa Al Ghul. She took over the League of Assassins and"¦did pretty much nothing until she was car-bombed to death in the lesser part of a Robin run that was pretty good otherwise. Nyssa was a good character, and they could have used her very effectively. But people wanted Ra's back, and we missed out on that.

Ra's is a good character, but he'd been around for decades at that point. It was time for a breath of fresh air, but instead, it was snuffed out too quickly. Ra's died numerous times over the years, and used the Lazarus Pits to return, but the truth is that anyone could use the Pits.

It didn't have to be good old Ra's. and maybe it still shouldn't be.
