"As for Hydro Man, it was a long time ago, but I think we weren't allowed to use Sandman, because he was going to be the villain in the Jim Cameron Spider-Man movie that never happened. So, John just substituted Hydro-Man. I kind of hoped the fact that he went to prom with Mary Jane made him slightly more interesting. (Total aside: Hydro-Man has Mary Jane meet her at the Hotel Seville, which was where I lived when I went to NYU. Now you know.) And the Spot? Well, I think we introduced him just to make an excuse for those interdimensional portals we used over and over again in lieu of killing people. He was such a silly character, that the only thing I remember about writing that was trying to jam as many puns off the word spot into the script."
