Larson’s Carol Danvers doesn’t really have too many prominent villains that she can call her own, but one obvious candidate is Dr. Karla Sofen, a.k.a Moonstone. In the comics, Sofen is a morally bankrupt psychiatrist until she got her hands on an alien rock called a moonstone. The object is a fragment of the Lifestone Tree, which consisted of artifacts left over from the Big Bang.
According to Deadline, Velvet Buzzsaw‘s Zawe Ashton has been cast as the main villain in the Captain Marvel sequel. The outlet didn’t specify the exact villain who Ashton will be portraying
Just one use can imbue anyone who holds it with extraordinary powers, with the moonstone giving Sofen similar abilities to Danvers. This was how she easily replaced her for a time in the comics as a member of The Dark Avengers.
