Mega Man: Upon a Star

The anime (episode 2, to be exact), where Rockman travels from the Game-World to the real world to learn some cultural differences about Japan, was intended to be a special episode for the original Mega Man cartoon series by Ruby-Spears, which aired around 1995 in the United States. As it seems, the special was finished before Ruby-Spears decided to redo their whole show with a completely new design better suited for American audiences.<br><br> Not fitting the new style anymore, it never was included in the series. Still, two more episodes about the same story were produced a bit later, this time under the main title "Rockman" (unlike episode 2, where he's called "Mega Man" even in the Japanese dub).<br><br> It's unknown if these 3 episodes ever saw an official release, until 2002, when Capcom of Japan decided to finally release them on DVD for Rockman's 15th Anniversary, all featuring a Japanese and English dub, but no subtitles. It's unknown if there are any more secret animated works of the original Rockman game series.
