Theory for ???'s identity in Supergirl (2025-) #4
So the 2025 August DC Comics Solicitations recently released, and for Supergirl they brought a bit of mystery with them as well.
Beware of potential spoilers...
Lesla-Lar and Lena Luthor were both of course already known to appear from the past solicits.
But this issue also features a mystery character marked only as ???.
I have a very strong hunch as to who this is.
Supergirl (1972-1974) #1
Meet Wanda Five. Notice the similarities in both hair and attire to ??? above?
When Kara (as Linda Danvers) enrolled in Vandyre University, Wanda was introduced as her roommmate, and quickly established as quite the mysterious woman.
Not only does Wanda have a rather unusual surname, but she also possesses psychic powers (which she used to help Supergirl catch a murderer). Wanda also owns a statue made from metal from outside the solar system.
Despite all these oddities and set-up, Wanda never returns. Nor do I believe she is mentioned, despite being Kara's roommate.
Given how inspired SUpergirl (2025-) is by pre-crisis Supergirl, I do think it seems likely that it might pick up old plotlines like this.
