Mega Man 5, known as Rockman 5 Blues no Wana!? (ロックマン5 ブルースの罠!?, Rokkuman Faibu Burūsu no Wana!??, lit. "Rockman 5 Blues' Trap!?") in Japan, is a video game developed by Capcom for the Nintendo Entertainment System. It is the fifth game in the original Mega Man series and was originally released in Japan on December 4, 1992. It saw a release during the same month in North America and in 1993 in Europe. The plot takes place after the fourth defeat of the evil Dr. Wily at the hands of the heroic robot Mega Man in the year 20XX. Mega Man's brother and ally Proto Man uncharacteristically leads a group of menacing robots in attacks on the world and kidnaps his own creator Dr. Light, leaving Mega Man little choice but to take up arms in a fight against his once trusted sibling. Mega Man 5 carries over the same graphical style and action-platforming gameplay as the four preceding chapters in the series. The game introduces a new character, Beat, whom the player can use as a weapon once a series of eight collectable letters are found. Mega Man 5 was met with an average to fairly positive critical reception, with the one major complaint being its lack of originality in either its plot or gameplay. Like other NES games in the series, Mega Man 5 has been re-released in Japan on the PlayStation, PlayStation Network, and mobile phones; in North America as part of the Mega Man Anniversary Collection; and in both regions on the Wii Virtual Console. It has been released in North America, Europe, and Japan on the 3DS Virtual Console.

Mega Man 6, known in Japan as Rockman 6 Shijō Saidai no Tatakai!! (ロックマン6 史上最大の戦い!!, Rokkuman Shikkusu Shijō Saidai no Tatakai!!?, lit. "Rockman 6: The Greatest Battle Ever!!"), is a video game developed by Capcom for the Nintendo Entertainment System (NES). It is the sixth installment in the original Mega Man series and was originally released in Japan on October 5, 1993 and in North America the following March. It was included in the Mega Man Anniversary Collection released in 2004. Its first PAL region release was June 11, 2013 for the 3DS Virtual Console, nearly twenty years after the game's first release. The story of Mega Man 6 opens during a competitive robot fighting tournament with entrants from all around the globe. A villainous figure known as "Mr. X" announces he has reprogrammed the eight powerful contestants with intent to use them for taking over the world. The game's robotic protagonist Mega Man, who was sent to oversee the tournament, springs into action to foil X's plot. A standard action-platformer, Mega Man 6 plays nearly identically to its five predecessors with a few added features such as stages with alternate pathways and new Rush adaptors. Mega Man 6 is the first game in the series to receive character design input from fans outside of Japan. This late-era game was also the last in the series released on Nintendo's 8-bit console. Due to the declining support of the NES and the growing presence of the newer and more powerful Super Nintendo Entertainment System (SNES), Capcom decided not to publish Mega Man 6 in North America. The North American version of Mega Man 6 was released by Nintendo of America instead. Critical reviews favored the game's comparable presentation and use of the established gameplay model from preceding chapters in the series, though nearly all judged it a redundant sequel. While the first five Mega Man games are available on the Wii's Virtual Console, this game is absent from the Wii Shop Channel; however the game was released via the 3DS Virtual Console in Japan and Europe, with North America on June 20, 2013.

The player takes control of a special forces operative Solid Snake who is assigned to find the titular superweapon "Metal Gear", a bipedal walking tank with the ability to launch nuclear weapons. Several sequels have been released for multiple consoles after requests from Konami to produce new Metal Gear games.

Various parts were inspired by Hollywood films with character's names, settings and artworks often referencing them.
