Sergei Kravinoff is a maniacal big game hunter known as Kraven the Hunter who seeks to defeat Spider-Man to prove that he is the greatest hunter in the world. Unlike other hunters, he typically disdains the use of guns or bow and arrows, preferring to take down large dangerous animals with his bare hands. He also uses a mystical serum to give him similar strength to Spider-Man, but even without the serum he is a threat to the wall-crawler. Spider-Man proves a frustrating quarry because Kraven continually underestimates the superhero's resourcefulness.
