Over the years, Hasbro has made several heroes and villains of the various Marvel Comics characters with their popular "Marvel Legends" toyline. Hasbro has released a few waves of "Marvel Legends: Spider-Man" action figures, based on Marvel's flagship comic book hero.  In recent years, Hasbro has made figures of such popular Spider-Man villains in their classic uniforms, such as Doc Ock and Mysterio in 2018, Kraven the Hunter was re-released with a new head sculpt as part of a Target exclusive two pack with Spider-Man in his black costume in 2019, and a new classic Vulture figure will be released in the spring of 2020.

However, two of Spider-Man's classic enemies and the remaining members of the classic comic book team, the Sinister Six, have yet to be made in their classic costumes as sold-separately action figures: the Sandman and Electro.  While the Sandman was made as a Build-A-Figure during a previous wave of "Marvel Legends: Spider-Man" figures, many collectors were unable to buy all the figures to create the figure to add it to their collection due to some figures being harder to find than others and other reasons. Electro was made into a figure in the Space Venom Build-A-Figure series, but it included the character in his modern costume and the figure only had a pair of hands that fired electrical blasts instead of including an alternate pair of "normal" gloved hands without the blast effects.

With Hasbro possibly losing the license to make Marvel figures in late 2020, we, the fans, hope to see Hasbro make all-new figures of the classic versions of the Sandman and Electro as soon as possible so fans can add them to their collection.
