Profile: Sapphire Stagg-Mason
First appearance: The Brave and the Bold #57, Dec/Jan 1964
History: the daughter of crooked scientist/industrialist Simon Stagg, she became Rex Mason/Metamorpho's girlfriend (and later wife) and loved him even after he was turned into a man of the elements by the Orb of Ra, which he'd been seeking in Egypt for Simon.
Was subjected to the following act of discrimination: when a miniseries for Metamorpho was written in 1993, Sapphire had decided by the end that her crooked father Simon Stagg was not worth supporting anymore, and had left him. But several years later, when JLA #52 was written up, this worthy development was ignored, and she was back in Simon's company again as though nothing ever happened. This was certainly also the case by the time Birds of Prey 51-52 Volume 1 was published in 2003.
What's wrong with how this was done? It has the effect of making Sapph-baby into a bimbo, but if anything, it certainly makes a mockery out of everything prior. Of course, it's the writers who have to shoulder the blame. What's surprising is that Mark Waid, who wrote the 1993 miniseries for Rex, inexplicably reversed this turn himself circa the time his JLA run went to press, and if he did, that's downright peculiar.
It's a pretty good demonstration of how plausible story development went out the window at DC as the 1990s came about.
