Profile: Katma Tui
First appearance: Green Lantern #30 Vol. 2, July 1964
Current status: dead since 1988
Was subjected to the following act of discrimination: in Action Comics Weekly #602, she was slain by Star Sapphire, some time after Carol Ferris had fallen completely under the control of the Zamaron device that had taken control of her to begin with, and was possessed by the Predator. Katma's since-widowed husband, John Stewart, was outraged at fellow Green Lantern Hal Jordan for this. Katma was resurrected in 1992 at the end of GL: Mosaic, but this was ruined yet again when Zero Hour took place, and she was among those killed.
What’s wrong with how this was done? It couldn’t possibly be simpler to explain: cheap-jack wipeout of a pretty good character, presumably because they didn’t know what else to do with her. Christopher Priest may have written the storyline at the time, and it was simply dismaying. And the editors of ZH who decided to off Katma yet again after all the trouble taken to bring her back weren't doing any favors either.
Personally, I’d think it’d be high time already to bring Katma Tui back, but…who at DC Comics is going to do it now?
