Onesided crossovers officially take place within one continuity, but not the other. Given that some characters may be parodies of their original counterparts, they could potentially get a separate profile scaling from the other verse based on their importance to the story.
One example is the version of Dante in
Megami Tensei, who is based on his
Devil May Cry counterpart, with the same name and appearance, but a slightly altered story to fit in more with the Shin Megami Tensei verse. However, the character in question may
not be used to scale to the Devil May Cry cast.
Profiles for crossovers not canon to the main story of one or more of the franchises involved may only be created according to the regulations defined in the
Canon page.
Canon crossovers officially take place within both continuities, and as such recurrently happen within a shared universe or feature characters made by the same creators. Examples include Mario Vs Donkey Kong or Dead or Alive/Ninja Gaiden. It is canon to both franchises and feats/scaling may be used if they are consistent.
We still have to differentiate between characters of different comparative power levels within the verses, and there may be
outliers and
Plot-Induced Stupidity, which are rules that still apply to linear canon verses.
Additionally, the feats seen or taken from the crossover may be consistent to one verse and not the other. There could be impressive feats seen as consistent with the established scale of one franchise, but that lack consistency with the otherwise featless franchise. We should only use scaling that does not contradict the statistics of the franchises, and need to use common sense for case-by-case analysis in addition to this.
This includes considering the contexts based on the nature or portrayal of the characters. For example, while Final Fight has shown very limited feats, characters such as Mike Haggar, Cody, and Hugo are consistently comparable to various
Street Fighter characters and could scale to their feats.
Take note that crossovers should preferably be referenced within the separate story settings themselves at some point in order to count as official on each side.
