A crossover is the placement of two or more franchises and merging them into a single story. Normally for fanservice reasonings. Crossovers vary greatly in terms of continuity and usually are made purely to put a bunch of fan favorite characters in one area. For more information on how canon is handled, please read the Canon page and the How to Handle Canon page as a lot will be taken from that when dictating crossovers.

Types of Crossovers

There are many types of crossovers, and each have typical explanations behind events. The following are:

• Single Franchise Crossovers: These are crossovers that are within a single franchise. They are normally the most common crossovers as they're the type people normally don't realize are crossovers. Marvel and DC are famous for this, where Spider-Man meets with the X-Men or Hulk battles Thor, or Superman meeting Batman. The Justice League and Avengers comics are natural single franchise crossover comics too. Other popular examples is Dragon Ball, where it has crossed over with Dr. Slump, both series being written by Akira Toriyama. Single Franchise Crossovers are naturally canon and within continuity by default as it is everything made by the author crossing over. Another example can be seen with the Megaten series with many of its characters from different spin-offs meeting up, such as Raidou from the Devil Summoner: Raidou Kuzunoha series being in Shin Megami Tensei: Nocturne. Another example can be Ninja Gaiden and Dead or Alive.
• Two-Sided Crossovers: These are crossovers that are acknowledged by both sides, an example of this is the Jimmy Timmy Power Hour series. These events are acknowledged by both sides as actually happening. Another popular example is the Marvel and DC crossovers, these are canonically events/universes made when Eternity sleeps with Kismet to make them. Mortal Kombat vs. DC Universe is another example.
• One-Sided Crossovers: These are crossovers where the events exist in one series but not the other. An example of this can be seen with the crossovers such as Star Detective Precure and Detective Conan. Each respective had their own crossover episode that dealt with different events.
• No-Sided Crossovers: These are crossovers where the events exist in neither series and exists as its own thing. Typical examples are series like Super Smash Bros. where the game takes place entirely in the "World of Imagination."
• Non-Canon Crossovers: These are crossovers that are largely fanon crossovers. They lack any real official backing behind them and are normally made by fans.

How to Handle Crossovers for Canon

Crossovers are considered canon if there are no present contradictions or word from the author that denies this claim. Especially if they have an in-universe reason for the crossover happening.

Mario and Donkey Kong would naturally be a Single Franchise Crossover.

Mega Man's crossover with Dragalia Lost, where it's noted that Mega Man and co. are there because Dr. Wily discovered and entered an interdimensional rift connecting his world and Grastaea. This would be a Two-Sided Crossover.

Though crossovers like Marvel vs. Capcom falls under the assumption that the Marvel and Capcom Earths merged and the characters have naturally existed together, like MvC Infinite. These would effectively be a No-Sided Crossover.

While they're heavily context based, there will usually be a story or author reasoning for why the crossover isn't considered official or apart of continuity.

Abilities in Crossovers

Though even if a crossover is a one-sided or no-sided crossover, there are cases where things can still be used for it.

For example, Shin Megami Tensei: Nocturne and Dante from Devil May Cry is a one-sided crossover for Nocturne. Though in official documents it notes that Dante's skills used in Nocturne have almost the same names and effects as they do in DMC, thus it is fair to use scans from his abilities in Nocturne for his canon profile. The same could be said to resistances, skill, and intelligence.

Powerscaling in Crossovers

In crossovers the authors are usually not considering feats beyond a typical basis. A normal assumption will be Spider-Man is not on the same punching level as Superman in a crossover, though this is not something automatically attributed to someone like Venom, a consistent rival to Spider-Man. They will even Venom overpower Superman. This is due to Venom's archetype. Venom is a rival and sometimes treated as a horror movie monster, so even if his equal is weaker then an opponent for the sake of a story.

In cases the question would be when to establish archetypes and when not to.

For cases where Crossover Scaling can be used apart of the Tiering System:

• The characters normally are around the same tier in terms of Codex Statistics.
• The characters are not merely just being compared as equal due to archetypes but they also directly show feats outside of powerscaling that allows them to be comparable.
• When matching the other in strength and speed they directly note things like "they can match my [insert speed here]", normally something like "mach speed", "light speed", or more.
• Normally for single franchise crossovers they would fall under the tiering due to similar systems. An example of this is Street Fighter & Final Fight.

For cases where Crossover Scaling can be used apart of the Archetype:

• The characters are completely different in tiers but they are only able to fight due to how each of their archetypes work. An example of this is Aladdin vs. Hercules where Aladdin utilizes his surroundings and expertise to overwhelm Hercules.
• Characters do not show remotely the strength/speed levels and have several narrative showings and statements of being far below another character's best feats and they can only fight them in a crossover due to there needing to be a plot. Arknights and Rainbow Six Siege collab as an example. Another example being the Alucard in Call of Duty.
• If the characters are directly noted to be amplified by another source. DC KO as an example where some of the crossover characters were amplified to fight against the DC cast. This can also be seen with Dead By Daylight where characters are helped by The Entity.
• Cases such as Mortal Kombat vs. DC Universe where the rage granted by Dark Kahn grants strange fluctuations of everyone's powers, making characters like Batman being comparable to Flash. In these cases the characters powers are canonically fluctuating.
