Does anyone know the history of why the villains in this ride changed from the concept phase of the ride?
Originally the ride was supposed to the feature Lizard instead of Hydro Man, Green Goblin instead of Hobgoblin, and Vulture. Both Lizard and Green Goblin are far more recognizable Spiderman villains when compared to Hydro Man and Hobby, and I'd argue Vulture is about on the same level as Electro, but definitely more well known than Scream.
Here's some concept art I found online that show sewer scene that originally was to include Lizard:
