Wait, wasn’t Nagini the name of Voldemort’s snake? Yes. This is that Nagini (Claudia Kim). Apparently, Nagini was a woman before she became one of Voldemort’s serpent companion. Rowling revealed on Twitter that Nagini is a Maledictus. She was born with a blood-curse that will eventually cause her to turn into a serpent for good. For now, she can transform in and out of her snake form at Circus Arcanus. That’s all we know, though. Her character is otherwise shrouded in mystery.
