The bodysuit she is wearing in Melbourne was reminiscent of the "Black Panther"-inspired number she debuted at the 2018 French Open—her first major tournament since marrying and giving birth to daughter Alexis Olympia Ohanian Jr.
"I feel like a warrior in it, like a warrior princess kind of, queen from Wakanda, maybe," she said at the time. "I'm always living in a fantasy world. I always wanted to be a super hero, and it's kind of my way of being a super hero. I feel like a super hero when I wear it."
Equally super was Serena's play on court against Siegemund; though the American conceded she felt more comfortable on court last week during the Yarra Valley Classic, there was plenty for the former world No. 1 to be pleased with after having to withdraw from her scheduled semifinal against Ashleigh Barty due to a shoulder injury.
"I was happy just to get through it," she said on Monday. "Wasn't sure how my serve would be after a little bit of that shoulder, but it's feeling good, I'm feeling good. So it felt really good."
The No. 10 seed will next face Nina Stojanovic in the second round.
