History
Doctor Mariah Crawford travelled to Africa to investigate after Dr. James Reeves went missing while researching in the jungle. Mariah and her team hired Sergei Kravinoff, a skilled hunter to guide them. Sergei acted as her bodyguard against the wild animals of the jungle, and he and Mariah fell in love.

Months later, they found Reeves, who had developed a formula to protect himself from infection in the jungle. However, a side effect meant that he had turned into a feral creature. Before disappearing forever, Reeves gave Mariah the last of the drug, warning her not to use it on herself or another person under any circumstances.

Mariah travelled back to America to work on a cure for Sergei, who also returned after thinking that she was seeing another man. He confronted Mariah, demanding the truth. Spider-Man interrupted and fought Kraven, with Kraven eventually disappearing and Spider-Man having Mariah hide in his friend Robbie's home. However, Mariah was eager to get back to her work on a cure quickly and left, returning to her lab. Her scent led Kraven to Robbie's, and Kraven believed he was Mariah's "other man", kidnapping Robbie, and telling Spider-Man that he must bring Mariah to him to ensure his friend's safety. Spider-Man did so, and after Kraven was defeated Mariah gave him a serum to cure him, and the two returned to Africa.[1]
Mariah and Sergei later returned to New York once again after Spider-Man developed a mutation disease. After Spider-Man turned into the Man-Spider, Mariah developed a formula which would reverse this and keep him from mutating again providing he take a serum every twenty-four hours (although he was eventually rid of the mutation altogether).[2]
