A few week ago saw Sharon Stone make mention she has a "wee" role in a Marvel movie.
Now we get a further tease from the actress as it's revealed her character has heat powers.
In an interview with the AARP, it's revealed: "she'll only reveal that her secret power is heat — in a yet-to-be-named movie, also for Marvel."
As Sharon Stone insinuated she had a "small" role in a Marvel movie, I speculated she might be playing Janet Van Dyne in the upcoming Ant-Man & Wasp movie, opposite her Basic Instinct co-star, Michael Douglas. However, "heat" doesn't really apply to Wasp as in the comics her powers are bioelectric energy blasts, but I suppose they could be thought of as "hot."
There was also a rumor that Sharon Stone might appear in Guardians of the Galaxy 2, so off the top of my head, Frankie Raye Nova also comes to mind. Update: Fox probably owns the rights to Frankie Raye (w/ Fantastic Four), so that's out of the question.
Update #2: It's possible Sharon Stone may be playing original Guardians of the Galaxy (comics) member Nikki, who was genetically engineered to live on the planet Mercury.
It's always possible that Sharon Stone could simply have a cameo in a Marvel movie with some sort of heat powers in a new/unnamed role.
