My money is on him being Chameleon but the fact that everyone is visually seeing him as Kraven makes a lot of sense seeing as how Dmitri Smerdyakov is the half brother of Sergei Kravinoff. Maybe it’s a twofer! With the movie being called Far From Home, maybe we’ll see Spidey in Europe? That’d be an easy way to introduce both Chameleon and Kraven. I suppose that all depends on the resolution of Infinity War Pt. 2!
