When referencing Scarlet Spider of the main Marvel universe, you are likely referencing Ben Reilly, the perfect clone of Peter Parker. You may also be referencing Joseph Wade, a former FBI agent turned into an evil version of the Scarlet Spider by Lady Octopus, any of the members of the Scarlet Spiders, or Kaine, another clone of Peter Parker who, now cured from his lethal condition, took the mantle of his fellow, previously deceased, clone.
