MegaMan NT Warrior (manga)

MegaMan NT Warrior (Rockman.EXE in Japan) is a manga authored by Ryo Takamisaki. In Japan, it was serialized in Shogakukan's CoroCoro Comic and later published in 13 volumes between 2002-2006. The manga was published in English by VIZ Media between 2004-2008, and retains its right to left format of reading.

The English manga, for the most part, uses the new set of names and terms that were established in the English MegaMan NT Warrior anime (instead of retaining the game names or original Japanese names), and since the English manga was released more quickly than the English anime, any new characters that did not yet receive English names in the anime instead retained their names from the English games. Following suit with the conclusion of the Mega Man Battle Network games, the manga officially ended at Volume 13.

Rock & Forte: Their Journey
This is the additional chapter included in the reprint version that split into two parts. According to Ryo Takamisaki himself, the chapter is his own personal project, not officially written by Capcom though he received permission to publish it. The chapter was first hinted in 2015 in Takamisaki's twitter before it was officially announced with a teaser artwork in 2016. This chapter serves as a midquel that takes place between after MegaMan defeated the Cybeast and before his return. After defeating the Cybeast, MegaMan was blown to the end of the Cyber World. He forms a truce with Bass who was also got blown away there and the two travels together to return to the original Cyber World. After a year traveling together, they finally found the way to return by using a Remote Gate attached to the remain of Gregar's data. Bass helps MegaMan to get into the Remote Gate that lead him back home while he stays behind and kills the bug. Bass then continues his journey, but is then approached by the revived Serenade who reveals he has been watching ever since he started his journey with MegaMan and offers to accompany him in MegaMan's stead, an offer that Bass refused but Serenade still follows him because he is lonely, much to Bass' dismay.
