Ultron and Kang for Avengers big bad's

I think Chameleon would be a great Spidey-Villian for this new go-around. The CGI and Special Effects for today are plenty advanced enough to pull him off.

Apocalypse would be great to see the x-men fight, but I wonder if he is too complex and big a villian to shove into one film. I don't want some watered down crappy version of him like we got with Venom in SM3
