Who is the black girl in Venom?

I'm curious, who exactly is the black girl in the movie "Venom"? Is she a new character introduced in the Marvel Cinematic Universe, or is she a reinterpretation of an existing character? And what role does she play in the story? I'm eager to learn more about her background and motivations, as well as her connection to the titular anti-hero. Is she a friend, a foe, or something else entirely? I'm intrigued by her presence in the film and would love to hear more about her.
