someone "worse", but I somehow doubt it would be a major character. Might be an obscure gangster villain.
My pick would be the Lobo brothers, the Mexican gangsters who menace Spider-Man for a few arcs many years ago. They are 'officially' mutants but never had ties to the X-Men comics. I feel safe in speculating that they are far down any list of villains for the MCU Spider-Man films.
This way you could have Kraven hunting animal-themed antagonists who are just as bad as him.
