View source for Episode Zero: The Beginning

{{trope}}
Well math says that 0 comes before 1, so putting "Zero" in the title of a work, or episode of that work, can be a good shorthand that a work is a [[Prequel]], prologue, or even a remake of a first chapter. Some comic book origin stories are shown in issues numbered 0.

'''Of course if "Zero" is in the title for any other reason, it doesn't count (as it wouldn't be the beginning). So works like ''[[Mega Man Zero]]'' and ''[[Phantasy Star Zero]]'' wouldn't be an example.'''

'''Also, the names have to be official, not [[Fan Nickname|fan nicknames]].'''

Compare [[Numbered Sequels]], [[Unusual Chapter Numbers]], [[Year Zero]].

{{examples}}

== Anime and Manga ==
* The ''[[Haruhi Suzumiya]]'' episode "The Adventures of Mikuru Asahina Episode 00" (though that's more of a subversion, since the episode mainly comprises the SOS Brigade's school movie that's produced in the middle of the series, and will be ''completely'' incomprehensible to anyone who isn't familiar with the show - and not much more comprehensible to those who are).
* ''[[Macross Zero]]''
* ''[[Ga-Rei Zero]]''
* ''[[wikipedia:SD Gundam Force Emaki Musharetsuden Zero|SD Gundam Force Emaki Musharetsuden Zero]]'' was a prequel to ''[[wikipedia:SD Gundam Force Emaki Musharetsuden|SD Gundam Force Emaki Musharetsuden]]''.
* ''[[wikipedia:Rose Hip Zero|Rose Hip Zero]]'' is a prequel to ''[[wikipedia:Rose Hip Rose|Rose Hip Rose]]''.

* [[Marvel Comics]] had a "Flashback Month" in which every comic published an #-1, set ''before'' the origin stories.

* ''[[Samurai Shodown]] V'', a prequel to the original game, was titled ''Samurai Spirits Zero'' in Japan.
