Ridley (Metroid)
Ridley's status within the ranks of the Space Pirates is unclear, with some sources stating that he is the leader of the entire Space Pirate race, whereas others portray him as simply the Pirates' military commander or even a mere enforcer within the Pirate military ranks, subservient to Mother Brain or Space Pirate High Command. Regardless, he is consistently depicted as a ruthless and cunning tactician who never passes up an opportunity to bring his considerable ferocity to bear on the battlefield, opting to overwhelm his opponents with an unwavering onslaught of attacks from his mouth, claws, and tail. He is also incredibly cruel, actively taking pleasure in the killing and torment of others; at one point in the official manga he taunts Samus by claiming he may have devoured her mother's corpse after killing her, and a Space Pirate log entry in "Metroid Prime" notes that being the mainstay of the Pirate security force is "a job he will certainly relish."
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.
