In the manga series ''[[Pokémon Adventures]]'', Team Rocket created Mewtwo, but some of its DNA is placed inside the Gym leader [[Blaine (Pokémon)|Blaine]]. Because of the DNA that they share, the two are unable to be separated for very long without becoming ill.<ref>{{cite book |last= Kusaka |first= Hidenori|author2=Mato| script-title=ja:ポケットモンスタースペシャル 3|year=1998 |publisher= [[Shogakukan]]|language= ja |isbn=978-4-09-149333-0 |chapter= Chapter 34}}</ref> Later, another Pokémon, [[Entei]], is able to break the bond between the two by removing the DNA in Blaine's arm, at which point Mewtwo leaves. It eventually helps the main character of the series, Red, fight against Team Rocket leader Giovanni and his [[Deoxys]].<ref>{{cite book |last= Kusaka |first= Hidenori|author2=Yamamoto, Satoshi| script-title=ja:ポケットモンスタースペシャル 24|year=2007 |publisher= [[Shogakukan]]|language= ja |isbn=978-4-09-140318-6 |chapter= Chapter 284}}</ref>

In 1998, [[Toshihiro Ono]] was asked to write a story detailing Mewtwo's origin to coincide with the release of ''Pokémon: The First Movie – Mewtwo Strikes Back''.<ref name="Onointerview">{{cite web |archive-url=https://web.archive.org/web/20000510020712/http://www.vizkids.com/pokemon/news_interview.shtml |title=Animerica Interview Toshihiro Ono |url=http://www.vizkids.com/pokemon/news_interview.shtml |archive-date=2000-05-10 |publisher=[[VIZ Media]] |access-date=2009-08-05}}</ref> The 52-page comic, presented in the form of a flashback,<ref name="Corocoro"/> was replaced midway by "The Birth of Mewtwo" animated short, resulting in little connection between Ono's work and the film.<ref name="Onointerview"/> Regardless, it saw print as a side story for ''[[Pokémon: The Electric Tale of Pikachu]]'' in the July 1998 issue of ''[[CoroCoro Comic]]''. In it, Mewtwo's creator, Dr. Fuji takes on the role of a coach for the fully developed Pokémon, while his employers, Team Rocket, test its abilities. Learning of a plan to mass-produce it as a weapon, Fuji approaches Mewtwo and tells it to destroy the lab and Fuji himself. Mewtwo refuses, stating it can not harm the doctor, who it regards as its father. Once captured by Team Rocket, Fuji tells Mewtwo that he is honored by the statement and is then killed. Angered by his death, Mewtwo destroys the lab and escapes. In the present, Mewtwo cries in its sleep as it dreams of the events.<ref name="Corocoro">{{cite journal |journal=[[CoroCoro Comic]] |date=July 1998 |language=ja |title=Dengeki Pikachuu: Myutsuu no Gyakushuu! |last=Ono |first=Toshihiro |pages=150–202 |author-link=Toshihiro Ono |issue=7 |volume=15}}</ref>
