List of Spider-Man enemies
As with Spider-Man, the villains' powers originate with scientific accidents or the misuse of scientific technology and also tend to have animal-themed costumes or powers (Vulture, Doctor Octopus, Beetle, Lizard, Rhino, Scorpion, Jackal and Black Cat). There also are supervillains with the powers over the elements (Sandman, Shocker, Electro, Molten Man and Hydro-Man), some that are horror-themed (the Goblins, Morbius, Morlun, and the Symbiotes) some that are crime lords (Kingpin, Tinkerer, Tombstone, Hammerhead, Silvermane and Mister Negative), and some that are masters of trickery (Chameleon and Mysterio). These villains oftentimes form teams such as the Sinister Six to oppose the superhero.
