That's because she played that part twice and has said some political shit
Even with her being a warrior her outfit in the MCU is very sexy.
Off looks alone she got that look.....
She's alluring yes, but never have been depicted as a sex symbol by any medias. I wouldn't put her in this category.
The only actresses playing in a MCU installment who are or used to be deemed as sex symbols are Evangeline Lilly (back to the 2000s, white folks were drooling over her lean, long athletic body and the producers behind the TV show "Lost" were consistently attempting to fetishize her character) , Lucy Bennett, Lucy Lawless (she did have a cameo role in an episode from "Agents of S.H.I.E.L.D.") , Karen Gillian, Zoe Saldana... and since a recent while, Zendaya.
Well, there has also Kristen Ritter, but whypipo are crazy. To me, neither her nor Lilly or Gillian belong to this category, while Bennett doesn't have the spice in spite being extremely pretty. Whom to Lawless, her fame precedes her.
Zendaya and Saldana, though... they're definitively seasoned for any cookout, brunch, quincacera party or mitzvah whatever. I cannot compare them to someone like Thompson.
