Who should round out The Sinister Six?

So, the lineup we'll get in S6 will most likely follow the Shazam lineup:



Green Goblin



Doctor Octopus



Vulture



Kraven



Mysterio



Rhino





But since there's a good portion of people who have no desire to see Rhino return, I decided to create a poll to see who they think would be a better option. This includes villains both used and unused.
