Calypso

Calypso was a feral creature that had been Mariah Crawford after she was injected with the same serum that turned Sergei Karvinoff into Kraven the Hunter. Calypso attacked people in a very horrible manner, putting some of her victims into comas. Spider-Man, Black Cat and Debra Whitman thought that Sergei was attacking the people since he looted Anatasia Hardy's lab to get his serum. Spidey, Black Cat and Sergei teamed up to stop Calypso. After Calypso had been defeated, she was restored to a partly normal form and ran off with Sergei.
