Marrying her to Black Panther did lasting damage to Storm.
When people talk about her being in the MCU, all they talk about is her being Tchalla's bitch, not her as a character in her own right. Same as the way people think Wanda should exist as a prop for Magneto.
It's notable that in the years since that marriage, she has become more and more sidelined, and like Janet, Wanda, and Jennifer, she has been shunted aside to make way for the new solo females like Carol, America, Kamala, Kitty, Gwen.
But, even with all this pushing, Marvel's ladies still suck.
