Kraven The Hunter

Kraven the Hunter is one of the most popular and important Spider-Man villains, and is a character in desperate need of the live-action treatment. Kraven is a maniacal big game hunter, who sets his sights on Spider-Man to prove that he's the greatest hunter in the world. He succeeds in capturing Spidey, then goes as far as to put him into a coma and bury him alive on his estate. Kraven's also important to the Spider-Man mythos at large, as he's the half-brother of another villain, Chameleon, and a founding member of the Sinister Six. It's hard to see how Kraven could fit into the first installment of this new Spider-Man reboot, but he'd be the perfect adversary for a sequel and could go on to become a fun villain in the larger MCU.
