*sigh*
The icon of MARVEL is Spider-Man.
...for now.
I'm rooting for Pak on this.
Writers don't determine Icons; actually no one pre-determines Icons. Do you think when they created Wolverine, they ever intended him to be one of Marvel's top 5 characters? Nope. If Byrne didn't save him from the chopping block, he would have entered limbo long before he ever became popular.
Characters become Icons when a number of things just happened to come together. For Wolverine, one of the things that happened was the advent of the Anti-hero hit at perfect time for Wolverine. But that wasn't the only thing. So many things have to come together.
All Pak can do is just write his best. Becoming an Icon is really out of his hands. Actually, trying to write her to make her an Icon will probably kill the title. And maybe even destroy the character, because in today's comic world, shock-value is one of the main ways to make a title and character stand out of the crowd.
And you really don't want him to use shock-value to make her an icon.
And it is also possible that making her an icon would destroy her. Batman, Superman, Wolverine; none of them look like their original incarnations. Batman and Superman used to be willing to kill. Wolverine has become "safe" (I mean, really, could you ever imagine the original and early versions of Wolverine being placed in the role of headmaster of a school?)
It would be just better that he writes the best he can and let the cards land where they land without trying to make (another) mark with her.
