I don’t think she’s a bad looking woman, but she doesn’t have the looks or personality that appeal to the mainstream (basically white people), who buy these events.
Last time I brought this up, someone tried to rebuttal using Serena, who is a poor example. They don’t look anything alike, and play different sports. When Serena came out, all the women wanted her body, and all the dudes wanted to smash.
As far as what she can control, getting so KO’s would definitely help.
