5) Rhino
Okay, now we’ve definitely seen this one before, but there’s always hope that his closing cameo in Amazing Spider-Man 2 left enough untrodden ground for a potential return to be considered. After all, the promise of the impending clash between Spider-Man and Rhino was probably one of the only things that would have dragged viewers back to the big screen for the now scrapped Amazing Spider-Man 3.
But even that version of the Rhino could still have been improved. While the mechanized Rhino suit has appeared in Spider-Man comics, the original version was an immensely powerful Aleksei Sytsevich who was enhanced by a series of chemical and radiation treatments. His Rhino armour was fused to his skin, and was designed to be as tough as the animal’s true hide.
This kind of brawn versus brain battle is a trademark of the Spider-Man world, and Rhino is the ultimate in brawny foes. The original version of the villain deserves a place on the big screen, and readers need only browse the pages of the Gauntlet storyline to see just how superior Aleksei is compared to the mechanized rip-off.
