I was just reflecting upon John Byrne's famous run as writer/artist on the Fantastic Four during the 1980's. His contributions to the quality of the title and the enrichment of its continuity are too multitudinous to enumerate in this venue so I'll just mention one.
It was during Byrne's run when it was finally realized that Sue Storm was on a different power level than her team mates. Rather than being the Achilles heel she had been portrayed as since the books inception, Sue, with her indestructible constructs, and perfect stealth, was actually the team's unsung powerhouse.
This was decisively depicted in Fantastic Four # 281 during which, due to circumstances too circuitous to name, Sue took on the rest of the FF and won. Easily
It was soon thereafter that she stopped going by the title Invisble Girl and adopted the monicker, Invisible Woman.
A great development, a long time in coming, crafted well by an excellent cartoonist.
I will always applaud that story arch, but I also must admit that there is a little part of me who will also miss the adorable "go to" hostage girl of bygone days.
