Spider-Man (Earth-20824)

The Spider-Man series that takes place in Earth-20834 was a short running video game series that followed the titular Spider-Man as the main protagonist for most games. The series started in 2000 with Spider-Man that released on the PlayStation, Nintendo 64, Dreamcast, and PC. A sequel was released exclusively on the PlayStation titled Spider-Man 2: Enter Electro. Another set of games that has alternate events was released on the Game Boy Color titled Spider-Man and Spider-Man 2: The Sinister Six. A standalone sequel for the Game Boy Advance was released that acts as as sequel to all four games titled Spider-Man: Mysterio's Menace.

In 2003, a video-game tie in to the second X-Men film was released on the PlayStation 2 titled X2: Wolverine's Revenge. This game features the same Spider-Man from the events of the first four games, and thus counts as canonical to that timeline.

These games are in the series of the first one which was my childhood game. I played the first game as a little kid on my Mom's N64 and I loved it so much. Finding out there were several sequels inspired me to play them all.

Spider-Man Games
This timeline of games follows the original Spider-Man through his encounters with Doctor Octopus and Electro. All of these games were 3D and released mostly on the PlayStation. They do not connect to the Game Boy Color games, but are prequels to the Game Boy Advance game.

Spider-Man (2000)
The game's story follows Spider-Man as he attempts to clear his name after being framed by a doppelgänger and becoming a wanted criminal, while also having to foil a symbiote invasion orchestrated by Doctor Octopus and Carnage. Numerous villains from the comics appear as bosses, including Scorpion, Rhino, Venom, Mysterio, Carnage, and Doctor Octopus, as well as a Carnage symbiote-possessed Doctor Octopus named Monster-Ock, who was created exclusively for the game as the final boss.

It is the sequel to Spider-Man (2000), and directly follows the events of that game, as Spider-Man tries to stop Electro from becoming all-powerful using a mechanism called the Bio-Nexus Device. Like its predecessor, the game features several classic Spider-Man villains as bosses, including the Shocker, Hammerhead, the Lizard, Sandman, and Electro, as well as his charged-up Hyper-Electro persona, created exclusively for the game.

Game Boy Color Timelines
All of these games are non-canon to the previous ones but act as alternate prequels to the GBA game, same as the others.

Spider-Man (2000)
An alternate telling of the original Spider-Man game released on the PlayStation and Nintendo 64. Spider-Man on the GBC doesn’t follow the same plot as the console game, but it does feature some of the same story beats, mainly Doctor Octopus using the power of the symbiotes for his own nefarious purposes and the inclusions of both Venom and Carnage. New to this game are Hobgoblin and the Lizard as additional boss characters, as if you’ll recall, the Lizard only had a brief cameo in all the other versions to give you some directions through the sewer maze.


 * Main Antagonist: Doctor Octopus
 * Final Boss: Monster-Ock
 * Released: 2000
 * Developer: Vicarious Visions
 * System: Game Boy Color



Spider-Man 2: The Sinister Six (2001)
The plot of the game revolves around the kidnapping of Aunt May and Spider-Man's efforts to save her from the group of villains who call themselves the Sinister Six: Mysterio, Sandman, Vulture, Scorpion, Kraven, and the mastermind of the group's plans, Doctor Octopus. Tired of having his plans foiled by Spider-Man, Doc Ock assembles a new Sinister Six composed of Mysterio, Sandman, Scorpion, Vulture and Kraven the Hunter. Their ultimate plan is to kidnap the caretaker of the photographer who takes pictures of Spider-Man, Aunt May, and force him to set a trap for Spider-Man. Unfortunately for The Six, that photographer is Peter Parker, AKA The Amazing Spider-Man, and they just went and made things personal.

United Timeline
The rest of these games are all sequels to the previous ones. The way the timeline goes is that the following games are all the inevitable outcomes of the previous games, even though they stem from different timelines.

Spider-Man: Mysterio's Menace (2001)
Taking place possibly a few months after Spider-Man 2: Enter Electro, the game begins with Peter Parker's wife Mary Jane Watson reminding him to buy a new fishbowl for their fish. After a news report however, Peter changes to Spider-Man and tries to investigate a few criminal activities all taking place in one night, which pits him against a rogue's gallery of villains, including Rhino, Hammerhead, Big Wheel, and Electro. They are led by the game's titular antagonist: the Master of Illusion, Mysterio. After subduing his fellow super-villains, Spider-Man defeats Mysterio himself in the final level. Mysterio escapes, but leaves his helmet behind. Peter brings it back home to Mary Jane as their new fishbowl.


 * Main Antagonist: Hammerhead
 * Final Boss: Mysterio
 * Released: 2001
 * Developer: Vicarious Visions
 * System: Game Boy Advance

Ambiguously Canon Content (X-Men Games)
Games that are debatable whether or not they take place in the same timeline as the rest of them.

X-Men: Mutant Academy (2000)
The first tie-in game for the first Fox X-Men movie, this game has little to nothing to do with X2 or what some people regard as "X3." It is a fighting game with minor movie relevance, but it is one of three games commissioned as movie tie-ins. Does that technically make it a prequel to X2? Actually no, it really doesn't. The only connection it has to the Spider-Man timeline is the fact that X2 features the same Spidey and it's technically a variant spawned from the same film. It branches off into it's own timeline of Mutant Academy games, one of which features Spider-Man, so the way this fucking timeline works is gonna be weird as shit.


 * Main Antagonist: Magneto
 * Final Boss: Magneto
 * Released: 2000
 * Developer: Paradox Development
 * System: PlayStation



X2: Wolverine's Revenge (2003)
Although not a Spider-Man game, this game features a deleted scene with the same Spider-Man from the previous five games, making it technically a part of the timeline. Wolverine fight his way past the heavily guarded areas of the Weapon X Facility to piece together fragmented clues to Wolverine's murky past and to save his life. Wolverine has 48 hours to find an antidote to the deadly Shiva Virus circulating in his bloodstream and the clues point to the Weapon X facility, the Canadian fortress where he had his skeletal structure fused with adamantium.


 * Main Antagonist: Weapon X
 * Final Boss: Lady Deathstrike
 * Released: 2003
 * Developer: Vicarious Visions
 * System: PlayStation 2



X3: The Official Game (2006)
It is technically a sequel to X2, as it's called X3, but it's more of a standalone sequel. The fact that no Spider-Man appears in it is also possibly a hint that it's not but whatever. The game covers the events between the films X2 and X-Men: The Last Stand, specifically following the characters of Logan, Iceman, and Nightcrawler. It also bridges the gap between the two films, explaining why Nightcrawler is not present for The Last Stand, and also introduces new foes for the game, such as HYDRA.


 * Main Antagonist: TBA
 * Final Boss: TBA
 * Released: 2006
 * Developer: Z-Axis
 * System: PlayStation 2



X-Men: Mutant Academy 2 (2001)
A sequel to the original Mutant Academy game, even though it isn't a movie tie-in, this game actually features Spider-Man! Therefore, for the sake of this timeline, it is an alternate sequel to the original game the same way that the prime Spidey games had alternate sequels. In this version of the timeline Spidey shows up to fight some villains with the X-Men, and in the original he meets with Wolverine briefly to talk about fighting Magneto. We know it's the same Spidey because he is voiced by Rino Ramano again, and an billboard advertising Enter Electro is present in the background of one of the stages.


 * Main Antagonist: Magneto
 * Final Boss: Juggernaut
 * Released: 2001
 * Developer: Paradox Development
 * System: PlayStation



X-Men: Next Dimension (2002)
This game is the third sequel to X-Men: Mutant Academy. It's actually the sequel to a comics story called Operation: Zero Tolerance. This game starts off with showing several gravestones indicating the deaths of different Marvel characters, one of which includes Peter Parker, which means that Spider-Man from Earth-20834 dies canonically between Mutant Academy 2 and Next Dimension. Wow.


 * Main Antagonist: Bastion
 * Final Boss: Bastion
 * Villainous Faction: Sentinels
 * Released: 2002
 * Developer: Paradox Development
 * System: PlayStation 2

The rabbit-hole goes so fucking deep by the way that the storyline extends into the fucking comic books. There are comic adaptations of one of the Spider-Man games, and the whole shit about one of the X-Men games being a sequel to a comic book is a whole nother thing. This list is exclusively for video games, though, so I won't be adding them, but if I truly decided to I could make a comprehensive timeline with every single thing I can find in it. It is a task my weird OCD brain might fucking consider doing because I'm fucking annoying. We shall see.

Here is a ROUGH version of the timeline that I'm gonna be adapting more thoroughly later.
