Dragon Ball Z: The History of Trunks (絶望への反抗!! 残された超戦士・悟飯とトランクス, Zetsubō e no Hankō!! Nokosareta Chō-Senshi • Gohan to Torankusu; lit. "Resistance to Despair!! The Remaining Super-Warriors, Gohan and Trunks") is a one hour-long TV-Special (#2) that is part of the Dragon Ball Z series of anime. Originally released in Japan on February 24, 1993, between episodes 175 and176. FUNimation Entertainment dubbed it into English and was released for the first time in English on October 25, 2000. The special was re-released in a remastered box set bundled withDragon Ball Z: Bardock - The Father of Goku in May 2008. Roughly a year later, FUNimation released a remastered single version on September 15, 2009.
The History of Trunks tells the story of Future Trunks and his life during the time where the androids have the world under siege. It is unique among Dragon Ball movies/specials since it is actually based from a brief chapter in the Dragon Ball manga, called "Trunks The History - The Lone Warrior". The special changes several key plot points for drama (such as that in the manga Trunks was capable of transforming into a Super Saiyan before Future Gohan's death).
