Crossover

A crossover is a fanfiction that combines two or more fandoms. They range from the almost likely to the completely implausible.
==Types of Crossovers==
===Standard Crossovers===
The most common kind, a standard crossover occurs when a fanfiction author smashes together two continua that are not canonically connected. This can be done very successfully, or it can leave the reader going "WTF?"
A good crossover meshes the worlds sensibly and interestingly. A poor crossover leaves gaping plotholes trying to explain away where incompatible plots in two different works of fiction would otherwise make each other impossible - or even worse, doesn't even try to make sense of it at all.
These crossovers will usually include a plot device to make interaction between the continua possible.
===Real World Crossovers===
Continua can be uncanonically connected to the Real World by virtue of a character from one world traveling to another by means of trans-dimensional hopping. Technically these stories are a type of crossover, but the contact between the two worlds is usually limited.
Very often, the main character from the Real World half of the crossover is a self-insert or an avatar. These character types are very prone to becoming Mary Sues if they fail to act, think, and grow as a real person would.
In the case of Trans-Dimensional Hopping, the crossover is done either by an OC traveling from the Real World to South Park, or an authorial influence or Mary Sue transports canon characters from their home continuum to the Real World. Unfortunately, what often happens is an insipidly cute sleepover at the writer's house, which, due to the boy's ages, can raise some unfortunate implications.
===Blender Crossovers===
In this type of crossover, different canonical characters from different continuums are 'revealed' to be actually the same person." For instance, Kenny is just a younger version of The Doctor from Doctor Who.
When the same principle is applied to canon settings, you get a standard crossover.
