While the Marvel characters, some didn’t get the chance to live up to their full potential. From Peter Parker’s heroic journey to his clashes with legendary villains, these films have left an indelible mark on superhero cinema. However, not every character in these movies has been given the treatment they deserve. Some figures with significant comic book legacies or intriguing potential were sidelined, underdeveloped, or reduced to mere cameos.

The modern era of Spider-Man movies began with Sam Raimi’s trilogy in the early 2000s. This was followed by Marc Webb’s two The Amazing Spider-Man movies, before the MCU timeline, as part of a collaboration between Marvel Studios and Sony Pictures. In each of these are the figures who had the potential to shine but were either mishandled or relegated to the sidelines in favor of other storylines or characters.

10 Ron Perkins’ Dr. Mendel Stromm

Spider-Man (2002)

Dr. Mendel Stromm made his live-action debut in Sam Raimi’s Spider-Man (2002). Stromm appears as a scientist working under Norman Osborn at Oscorp. While his screen time is minimal, his presence hints at a deeper narrative potential. In the comics, Stromm is a significant villain known as "The Robot Master" and a key figure in Norman Osborn’s transformation into the Green Goblin. His deep ties to Oscorp and scientific advancements make him a formidable foe for Spider-Man.

In the movie, however, Stromm is unceremoniously killed by Osborn during an experiment gone wrong. This abrupt end robs the character of any chance to develop into a meaningful antagonist. Considering Stromm’s comic book history as a brilliant scientist with a vendetta against Osborn and later Peter Parker, his inclusion in the film feels like a missed opportunity. By sidelining Stromm, Spider-Man sacrificed a rich narrative thread that could provide Peter with a new kind of intellectual challenge.

9 Dylan Baker’s Dr. Curt Conners

Spider-Man 2 & Spider-Man 3

Dr. Curt Connors appears in Spider-Man 2 (2004) and Spider-Man 3 (2007) as Peter Parker’s college professor and mentor. While it was certainly thrilling to see the character introduced, his role was confined to a minor ing part. In the comics, Connors’ transformation into the Lizard is one of Spider-Man’s most emotionally charged storylines, exploring themes of loss, humanity, and redemption.

After Spider-Man: No Way Home, Marvel and Sony have an even bigger task to make Spider-Man 4, but will Tom Holland return and would it be in the MCU?

Despite being set up as a potentially pivotal figure in Peter’s life, the Raimi trilogy never allowed Connors to evolve into the Lizard. This omission feels particularly frustrating given Baker’s compelling performance, which hinted at a complex character beneath the surface. The groundwork was there for a powerful story in which Peter’s mentor becomes a tragic antagonist, but it was never pursued. While The Amazing Spider-Man eventually brought the Lizard to life, the absence of this iconic villain in Raimi’s trilogy remains one of its most glaring missed opportunities.

8 Topher Grace’s Eddie Brock

Spider-Man 3

Eddie Brock’s transformation into Venom is one of the most iconic arcs in Spider-Man lore, but Spider-Man 3 (2007) turned it into a rushed subplot. Portrayed unconvincingly by Topher Grace, Brock’s character is introduced as a rival photographer to Peter Parker, but his descent into becoming Venom lacks the depth and emotional weight that made the character so compelling in the comics. In Raimi’s film, Eddie is portrayed as more of a caricature than a nuanced character.

His motivations - rooted in jealousy and revenge - are superficially explored, and his transformation into Venom is shoehorned into an already crowded plot. The film’s overstuffed narrative left little room for Brock’s arc to breathe, resulting in a version of Venom that felt underwhelming and one-dimensional. By failing to give Eddie Brock the focus he deserved, Spider-Man 3 squandered one of Spider-Man’s most popular and complex villains.

7 Michael Massee’s The Gentleman

The Amazing Spider-Man & The Amazing Spider-Man 2

The mysterious character known as The Gentleman, or Gustav Fiers, made subtle appearances in The Amazing Spider-Mannand its sequel. The Gentleman is depicted as a shadowy figure orchestrating events behind the scenes, including the experiments at Oscorp and the possible assembly of the Sinister Six. His cryptic conversations and sinister demeanor hinted at a grander plan that could have tied multiple storylines together.

Unfortunately, The Gentleman’s potential was never realized. With The Amazing Spider-Man 2 ending on a cliffhanger that teased the Sinister Six, plans for a follow-up were scrapped when the franchise was rebooted. This left The Gentleman’s role in the narrative unresolved, frustrating those who were eager to see his master plan come to fruition. The Gentleman’s inclusion in the films was an ambitious attempt to build a larger interconnected universe, but the lack of payoff rendered him a wasted character.

6 Paul Giamatti’s The Rhino

The Amazing Spider-Man 2

Paul Giamatti’s portrayal of Aleksei Sytsevich, aka The Rhino, in The Amazing Spider-Man 2 (2014) is a textbook example of wasted potential. Introduced as a bumbling criminal in the film’s opening sequence, Sytsevich reappears in the final moments wearing a mechanized Rhino suit. This climactic scene was clearly meant to set up future confrontations, but it ultimately served as little more than a teaser for a narrative that wouldn’t be completed.

10 Marvel Villains Perfect For Spider-Man 4 Now That It Has A Release Date

The MCU’s Spider-Man 4 will release straight after Avengers: Doomsday, hinting at the possible villain he will face, with some convincing options.

The Rhino’s brief and cartoonish portrayal was very disappointing, especially given the character’s storied history as a formidable foe in Spider-Man’s rogues’ gallery. Giamatti’s over-the-top performance, while entertaining in its own way, lacked the depth needed to make the character memorable. By relegating The Rhino to a glorified cameo, the film squandered an opportunity to explore his tragic backstory and his struggles with being manipulated by more powerful villains.

5 Felicity Jones’ Felicia Hardy

The Amazing Spider-Man 2

Felicity Jones’s brief appearance as Felicia Hardy in The Amazing Spider-Man 2 was initially exciting as she is the alter ego of one of Spider-Man’s most enduring characters: the Black Cat. In the comics, Felicia is a complex antihero who shares a tumultuous romantic relationship with Spider-Man, often blurring the lines between ally and adversary. She has never been depicted in live-action despite being a classic, beloved character. It seemed The Amazing Spider-Man 2 was finally delivering this.

Instead, however, Felicia is reduced to a minor Oscorp employee with no significant role in the story. Her character’s potential is completely untapped, serving mainly as an Easter egg. Though it’s possible that she was to be developed and explored fully in a subsequent movie, this went unrealised and therefore Felicia never debuted as the Black Cat. Given the Black Cat’s rich history and her unique dynamic with Spider-Man, the decision to underutilize Felicia Hardy feels like a cruel and hollow promise.

4 B.J. Novak’s Alistair Smythe

The Amazing Spider-Man 2

B.J. Novak’s portrayal of Alistair Smythe in The Amazing Spider-Man 2 is another example of wasted potential. In the comics, Smythe is a brilliant scientist who creates the Spider-Slayers, a series of robotic hunters designed to eliminate Spider-Man. His vendetta against the wall-crawler and his descent into villainy make him a compelling character. He is often characterized by his hatred for the Web-Slinger, inheriting his father’s Spider-Slayer operation and disdain for the hero.

In The Amazing Spider-Man 2, Smythe is relegated to a minor role as an Oscorp employee who bullies Max Dillon (Jamie Foxx) before his transformation into Electro. The character’s screen time is minimal, and there is no indication of his comic book legacy. By sidelining Smythe, the film missed an opportunity to introduce a unique and formidable antagonist who could have posed a significant threat to Spider-Man.

3 Donald Glover’s Aaron Davis

Spider-Man: Homecoming

Donald Glover’s portrayal of Aaron Davis in Spider-Man: Homecoming (2017) was exciting for several reasons. Firstly, Glover himself was the inspiration for the character Miles Moralez, creating a fun connection between the Spider-Man eras. Secondly, it was confirmed that Glover was playing Miles’s uncle in Homecoming. Glover’s performance was charismatic, and his character’s casual mention of his nephew hinted at the possibility of Miles entering the Marvel Cinematic Universe.

However, Davis’s role in the film is little more than a cameo. While his inclusion is a nice Easter egg for fans, it feels like a missed opportunity to delve deeper into his character. In the comics, Aaron Davis becomes the Prowler, a morally ambiguous figure whose actions have significant consequences for Miles and Peter. By limiting Davis’s role, the MCU missed a chance to explore this intriguing dynamic.

2 Logan Marshall-Green & Bokeem Woodbine’s Shocker

Spider-Man: Homecoming

Spider-Man: Homecoming introduced not one but two versions of the Shocker. Played by Logan Marshall-Green and Bokeem Woodbine, these characters serve as henchmen for the Vulture (Michael Keaton). While their inclusion adds to the film’s roster of villains, neither version of the Shocker is given enough screen time or development to leave a lasting impression. In fact, if Vulture hadn’t specifically called them Shocker, it would have been hard to discern their identity at all.

In the comics, Shocker is a skilled engineer who creates gauntlets capable of emitting powerful vibrations, making him a formidable foe for Spider-Man. He had numerous memorable appearances in Spider-Man: The Animated Series and is known as one of Spider-Man’s primary adversaries. However, Spider-Man reduces him to a minor antagonist with little backstory or motivation. By failing to explore the Shocker’s potential, Homecoming missed an opportunity to elevate one of Spider-Man’s more unique villains.

1 Michael Chernus’s Tinkerer

Spider-Man: Homecoming

Michael Chernus’s portrayal of the Tinkerer in Spider-Man: Homecoming completely squandered another classic Spidey foe. In the comics, the Tinkerer is a genius inventor who supplies advanced technology to various villains, making him a key player in Spider-Man’s rogues’ gallery. In the film, the Tinkerer serves as a background character, assisting the Vulture and his crew with their tech, making many of their weapons, including Shocker’s gauntlets and Vulture’s wings.

His role is purely functional, lacking the depth and personality that could have made him a standout character. While his associates were defeated and arrested by the authorities, Tinkerer’s fate remains unconfirmed. He could therefore reemerge working alongside another technologically advanced villain in the MCU’s future. Nevertheless, by underutilizing the character, Spider-Man: Homecoming missed an opportunity to explore his inventive genius and his potential as a recurring antagonist as one of Spider-Man’s most infamous foes.
