Dr. Octopus / Doc Ock in Green Outfit with Small Back Arms

This Dr. Octopus minifigure is desirable due to its unique combination of elements and its appearance in a relatively small and affordable Spider-Man set. The green outfit, while not his most iconic look, offers a distinctive variation for collectors. The inclusion of the small back arms, as opposed to the larger molded ones, also adds to its uniqueness.

The character's popularity as a classic Spider-Man villain further boosts its collectibility. Minifigures of well-known villains often hold value, especially when they have unique molds or prints. Collectors seeking to complete their Spider-Man rogues' gallery will likely seek out this version of Doc Ock.

This Dr. Octopus minifigure appears in only one set, the Spider-Man: Doc Ock Diamond Heist (76134-1) released in 2019. While not a limited edition or regional exclusive, the single set appearance contributes to its relative scarcity on the aftermarket. The set has been retired, meaning no new copies are being produced, which should drive up demand over time. Its availability depends on how many complete minifigures are still available from parted-out sets.

Given its limited availability and the enduring popularity of Spider-Man and his villains, this Dr. Octopus minifigure has good investment potential. The retirement of the set it appeared in suggests that its value will gradually increase as fewer copies become available. Although it's not the most iconic Doc Ock design, the unique elements and affordability of the original set make it an accessible piece for collectors, potentially driving up demand. The affordable price point makes it easy to invest in multiples.
