Rhino
VengefulAggressiveDim-wittedTerritorial
Once a small-time crook repeatedly humiliated by Spider-Man, Alexander O'Hirn underwent an experimental procedure that permanently bonded a silicon/titanium alloy to his skin, transforming him into the nearly unstoppable Rhino. With his immense strength and impenetrable armor, Rhino became one of Spider-Man's most physically imposing enemies and a founding member of the Sinister Six.
