Any time she's drawn? Did you ever see her in Generation X? You're gonna tell me none of these look black to you?

And when she first appeared as a character, she looked like this.

Still not black?
With Monet it's reversed. her father is black. Meanwhile because there was a white character named St. Croix, people headcanon it as her grandfather & use that to say she's not black. A white Ancestor doesn't = white.
Her skin has gotten whiter and her features have changed because in general, America still deals with tons of racial bias & they don't advertise what's seen as "too black."
The Rock is mixed but he's VERY ambiguous-looking & could pass for damn near any & everything. But in general, his blackness is not focused on much as a celebrity. During his years in wrestling, his Samoan heritage got all the attention, as a result he's not recognized by many fans as the first black WWE Champion, and instead Kofi gets that attention. Namely because he looks more black & many black people can identify with him before they can The Rock, who's seen as getting a lot more opportunity because he's "not too black." As someone questioned, would he & Vin Diesel be getting so much push & stardom if they were dark as Tyrese.
Storm's skin has gotten tan like Halle Berry over the years. Only time they really use dark skinned black women is if they're villains. Otherwise, they mostly stay in the back to get used sparingly if they aren't lightened up & toned down.
