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.

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 nicknames

Anime and Manga
- Aika Zero, a prequel to Agent Aika.
- Ga-Rei Zero-
- 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).
- Lupin III Episode 0 First Contact is a prequel explaining how the gang all met. Maybe. Not the only Origins Episode in a franchise that relies on Broad Strokes continuity, either.
- Lyrical Nanoha
- Macross Zero
- Mai-Otome 0~S.ifr~, a prequel to the other Mai-Otome films.
- Mobile Suit Gundam Wing: Episode Zero.
- One Piece: Chapter 0 serves as the backstory for many pivotal events, such as the old rival Shiki and his role in the canonical film "Strong World".
- Queen's Blade Rebellion Zero, a manga, althrough technically an interquel between the events of the QB's OVAs and the gamebooks' continuity version of Rebellion.

- Steel Angel Kurumi 0, a prequel to the Steel Angel Kurumi series.

- "Zero Month" following DC Comics' Zero Hour is a borderline case; the #0s all retell the heroes' origins, but in Flash Back, with a Framing Story in the present.
- They're doing another "Zero Month" for the one-year anniversary of the New 52 reboot.
- Before the New 52, there was an Issue #0 of Batwoman, which consists of Batman observing the heroine to get confirmation on her identity, eventually deeming her a worthy candidate for Batman Inc. It is included in the collected edition of the comic's first storyline. Funnily enough, this means that Batwoman has two Issue #0s in this continuity.
- Averted with in Green Lantern #0 and Green Lantern: The New Guardians #0; featuring new present-day origins (of Earth's newest Green Lantern and an overhauled New Guardians roster) instead of flashbacks.
- "Chapter 0: Of Ducks, Dimes, and Destinies", part of The Life and Times of Scrooge McDuck. Made after the series concluded, but given the "Chapter 0" moniker because it was a retelling of the first chapter detailing Magica de Spell's involvement during her time travel.
- Marvel Comics had a "Flashback Month" in which every comic published an #-1, set before the origin stories.
- More specifically, in most cases they were set before Fantastic Four #1, which started the Silver Age of Marvel.* Spider-Girl's first issue was numbered 0, and was a reprint of What If? v2 #105, the issue she first appeared in.
- Ninja High School received a Chapter 0, many years after it first began. It was an Interquel for Ichi-kun (after her grandfather defeated her in Chapter 1, but before her trip to America) and Asrial (after she was made aware of who she was being sent to marry, but before being transformed into a human form), but a Prequel for Jeremy (showing him the day before his introduction in Chapter 1).

- Dark Void Zero. Originally starting out as an April Fools joke based off of an 8-bit rendition of Dark Void's main theme, the game soon became a fully-fledged DSiWare title claimed to be a "legendary 'lost project'" of Capcom's, recently found locked away in their vaults.
- The Dating Sim Dream Club Zero, a prequel to Dream Club.
- Final Ninja Zero is a prequel to Final Ninja.
- Ko-ko-ro...0 is the third game in the Ko-ko-ro... H game series to be released, but the events of Ko-ko-ro...0 precede those of Ko-ko-ro... and Ko-ko-ro...II. Though incest and rape are primary themes in the series as a whole, one of the possible endings of Ko-ko-ro...0 (namely, the revelation that Kasumi is Souji's mother, not his older sister) turns the squick factor of the already quite squicky original game Up to Eleven.

Bison and Charlie's death).

- On the Origin of PCs, the first The Order of the Stick prequel, was published as issue number 0. Start of Darkness, the second prequel, takes place even earlier, so it's issue number -1.
- xkcd's print edition starts with volume 0. It's not a prequel, the author just likes zero-indexing.
