Sign in to your GameRant account Spider-Man is one of the most popular fictional characters on the planet. While Peter Parker is based in New York (aside from some globetrotting adventures), his influence and popularity extend around the world. As such, there are a lot of Spidey fans who are very familiar with his rogues gallery, which is one of the biggest and best in all of comics. However, there are a handful of villains who don't exist in the Spider-Man comics, and who have only appeared in video games. If you're a Spider-Man fan who is very familiar with his comic book history but haven't checked out any video game adaptations of the character, then these next villains have likely never popped up on your radar. The good news for you is that we've outlined them all here, and we even ranked them from weakest to strongest, just to show how ridiculously powerful these video game-exclusive Spider-Man villains can truly get.

For one, he's voiced by Val Kilmer, which is just a cool bit of Spider-Man trivia. Second, he's from the future — 2099 specifically — and is an expert in temporal physics. In fact, he runs the entire temporal physics division at Alchemax, a competitor of Stark-Fujikawa. He's also a rival and nemesis of Miguel O'Hara, aka Spider-Man 2099. Unfortunately for Sloan, Alchemax isn't faring too well in 2099 and is on the verge of being taken over by Stark-Fujikawa. Rather than let that happen, Sloan uses his expertise to travel back to the 70s, building Alchemax from the ground up and reshaping it in his image. He uses his knowledge of the future to his advantage, even hiring Peter Parker as an employee, since he knows that he'll eventually become Spider-Man. Meanwhile, Neuva York becomes a futuristic dystopia in 2099 due to Sloan's timeline alterations. Sloan's access to time travel definitely makes him a potent adversary. After all, it's hard to defeat a villain who both knows the future and can travel back in time to undo any weaknesses Spider-Man might exploit to take him down. That said, at the end of the day, he's still just "a guy." A very smart, very dangerous guy, but he doesn't compare to the other villains on this list. 4 The Flame The Devil You Know Appears In : Marvel's Spider-Man 2 Voiced By : Chad Doreck Slow down, angry commenters. I know, I know. Cletus Kasady is a character from the comics, and a pretty well-known one at that. He's Carnage, the hyperviolent symbiote who makes Venom look like a fun and chill guy by comparison. Carnage is one of the more iconic villains in Spider-Man's rogues gallery, and I'm definitely not suggesting that comic fans wouldn't have heard of him. However, The Flame is a different story. This version of Kasady is a new take on the character from Marvel's Spider-Man 2. Typically, Cletus starts as a serial killer, which makes him the perfect host for the unhinged Carnage symbiote. In this instance, Kasady is the leader of a cult called Followers of the Flame. He's working to enact something he calls "The Crimson Hour," which will supposedly purge the unworthy but spare his followers. Typical cult stuff, you get the idea. In the end, it's revealed that his true goal is to get his hands on a second symbiote, separate from the Venom symbiote that Peter and Miles are grappling with throughout the game's campaign. The thing is, The Flame is already a villain before it's revealed that he's also Cletus Kasady. He's a long-standing target of Yuri Watanabe, both as a police officer and as Wraith. Then, after their first showdown, he becomes Spider-Man's nemesis as well, and nearly kills him by dousing him in gasoline and attempting to set him on fire, only for Yuri to save Spidey's life. He's certainly a threat, but without the symbiote, or any real super-powered advantage, he can't compete with the villains below. 3 Phin Mason Tinkerer Teenage Angst With Advanced Tech Appears In : Marvel's Spider-Man: Miles Morales Voiced By : Jasmin Savoy Brown Much like Cletus Kasady, Tinkerer has been around in the comics for a long time. He is typically depicted as an old man named Phineus Mason, an engineering genius capable of creating advanced gadgets out of pieces of scrap. Sometimes he single-handedly tries to defeat Spider-Man, and other times he is more of a facilitator, supplying gadgets to other, more powerful supervillains. One thing Tinkerer has never been prior to Marvel's Spider-Man: Miles Morales is a teenage girl. Phin Mason is also an engineering genius, but of a different sort. She and her brother, Rick (the original Tinkerer in this timeline), created a powerful energy converter. However, when they learned that it was making people sick, they broke into Roxxon to destroy it, only for Simon Krieger to trap Rick inside the converter and kill him. This pushes Phin onto a path of revenge. Rather than building gadgets, Phin's focus is on programmable matter, which is exactly what it sounds like. Think MCU Tony Stark's nanotech, and you get the gist. In this case, Phin uses programmable matter to craft advanced weapons for a revolutionary group called the Underground, who plan to use those weapons to blow up Roxxon's lab. While she doesn't technically have superpowers, Phin's unmatched engineering talent and the potency of her programmable matter make her a worthy foe for Miles as he comes into his own as Spider-Man. 2 Monster Ock What If Doc Ock Was The Carnage Symbiote's Host? Monster Ock Spider-Man Appears In : Spider-Man: The Video Game (2000) Voiced By : Efrem Zimbalist Jr. The still beloved Spider-Man: The Video Game from 2000 was pretty groundbreaking for its time. It didn't revolutionize gaming or anything, but as far as superhero games go, it was one of the first to truly capture the spirit of the characters, and to look pretty good doing it. While the overall narrative is typical comic book fare involving Carnage and Doctor Octopus terrorizing New York, the climax offered something brand new: Monster Ock. This villain is the result of Spider-Man's initial defeat of Carnage, after which the symbiote abandons Cletus Kasady and instead bonds with Doc Ock. The resulting monster is the stuff of nightmares, and notoriously scared the socks off of many a young millennial gamer back in the day (myself included). His iconic line, "It's not over yet," is wildly disturbing, like Doc Ock speaking through a filter of symbiote slime. The thing is, there's a very good chance that Monster Ock is stronger than Spider-Man. Sure, Spidey comes out on top in the end, but only by using fire to literally melt the Carnage symbiote off of Doc Ock. It works, and it's a classic way for the webhead to win a fight that he should probably lose, but that doesn't mean he wasn't severely outmatched leading up to that point. Monster Ock can regenerate, has a Spider-Sense of his own, and can even manipulate minds. Surprisingly, we haven't seen this creature appear in other media. As it stands, he remains stuck in the 2000s. 1 Atrocity The Worst Of Both Worlds Appears In : Spider-Man: Edge of Time Voiced By : Fred Tatasciore To close things out, we have another Doc Ock amalgam, although this one is a bit more complex, and even more powerful than Monster Ock. Atrocity is the final boss of Spider-Man: Edge of Time. He is the result of Anti-Venom, Doc Ock, and Walker Sloan tumbling simultaneously into a timestream portal. He's a hulking beast with Doc Ock's tentacle arms, the Venom symbiote's monstrous build and deadly clawed hands, and presumably Walker Sloan's features somewhere as well. The latter is seemingly fully absorbed by Atrocity, because there aren't any details that express his involvement. We just know he's in there, and he's probably uncomfortable. What makes this Dock Ock-symbiote fusion so much more powerful than Monster Ock? Well, Atrocity has access to teleportation and time travel. Sort of. The creature's tentacles can literally shred the fabric of time, allowing it to attack Spider-Man in the present day and Miguel O'Hara in the future simultaneously. It's almost overkill how strong Atrocity is. The one advantage Spidey has against it is that (thankfully) Doc Ock's intelligence is significantly diminished. Put simply, the creature is dumb and gullible. In the end, Spider-Man defeats Atrocity by ripping off its tentacles and launching them into the future, which is pretty badass. Still, it's hard to argue that this creature wouldn't decimate any other villain on this list. Its sheer size alone makes it a formidable enemy, but once you add time travel to the mix? Forget about it. Atrocity is one of the coolest things to come out of Beenox's Spider-Verse duology of games, and is still one of the strongest Spider-Man villains to never appear in any other medium. Close
