First Appearance: The Amazing Spider-Man #41
Powers: Super strength, super speed, incredible durability and stamina. Some of these abilities come from a thick polymer suit he wears.  The rest are the result of years of chemical and radiation treatments.
Pros: Like the Sandman and Venom, Rhino would be the rare Spidey rogue who isn't a scientist or technological genius.  He'd also create a wave a destruction on screen similar to the Green Goblin, but on a much larger scale (a visual feast).  His super strength is nothing Spider-Man has faced on the big screen - so far.
Cons: Aleksei Mikhailovich Sytsevich isn't the smartest cook in the kitchen.  His back story also is one of the least compelling of any Spider-Man villain.  He's really just a thug who enjoys his power. The sequel's screenwriter would really have to change his backstory to make him interesting enough to be a primary villain.  As a secondary sparing partner?  That's a completely different story.
