Double Dragon (ダブルドラゴン, Daburu Doragon?) is a 1987 beat 'em up developed by Technōs Japan and distributed in North America and Europe by Taito Corporation. The game is a spiritual and technological successor to Technos' earlier beat 'em up, Nekketsu Kōha Kunio-kun (released outside of Japan by Taito as Renegade), but introduced several additions such as two-player cooperative gameplay and the ability to arm oneself with an enemy's weapon after disarming them. Double Dragon is considered to be one of the first successful examples of the genre, resulting in the creation of two arcade sequels and several spinoffs, as well as inspiring other companies in creating their own beat 'em ups. Home versions of the game were released for the Nintendo Entertainment System, Sega Master System, Atari 2600, Atari 7800, Atari ST, Amiga, Amstrad CPC, Commodore 64, Game Boy, Genesis/Mega Drive and Atari Lynx, among other platforms during the series's height of popularity. A remake titled Double Dragon Advance was released for the Game Boy Advance in 2003. The NES version was re-released for the Wii's Virtual Console in North America on April 28, 2008 at a cost of 500 Wii Points. Nintendo also released the Game Boy version on the Nintendo 3DS Virtual Console in 2011. Another remake was released for the iOS mobile devices in 2011, which features brand new gameplay, sprites and animations, and music. A new Double Dragon title, Double Dragon Neon, was released in 2012 for Xbox Live Arcade and PlayStation Network, and in 2014 for Steam and is considered a reboot of the series.

Double Dragon V: The Shadow Falls is a 1994 American-produced sequel to Technōs Japan's Double Dragon series. Unlike the previously produced Double Dragon games, Technōs had little or no credited involvement in the development of the game outside of licensing the series' name to publisher Tradewest (the publisher of the first NES version of Double Dragon and the Super NES title Super Double Dragon). Instead, the game was developed by Leland Interactive Media, a subsidiary of Tradewest. Unlike the previous games, which were side-scrolling fighting action games or beat-em-ups, Shadow Falls is a head-to-head fighting game based on the animated Double Dragon TV series in the style of Capcom's 1991 arcade-hit Street Fighter II. Technōs would later produce its own fighting game based on the Double Dragon movie the following year simply titled Double Dragon for the Neo Geo. Shadow Falls was originally released for the Super NES and Sega Mega Drive/Genesis, and later released for the Atari Jaguar by Telegames (publisher of the Atari Lynx version of the first Double Dragon) in 1995.

A dragon is a legendary creature, typically with serpentine or reptilian traits, that features in the myths of many cultures. There are two distinct cultural traditions of dragons: the European dragon, derived from European folk traditions and ultimately related to Greek and Middle Eastern mythologies, and the Chinese dragon, with counterparts in Japan (namely the Japanese dragon), Korea and other East Asian countries. The two traditions may have evolved separately, but have influenced each other to a certain extent, particularly with the cross-cultural contact of recent centuries. The English word "dragon" derives from Greek δράκων (drákōn), "dragon, serpent of huge size, water-snake".

Dragon Ball Z (ドラゴンボールZ(ゼット), Doragon Bōru Zetto?, commonly abbreviated as DBZ) is a Japanese anime television series produced by Toei Animation. Dragon Ball Z is the sequel to the Dragon Ball anime and adapts the last 325 chapters of the original 519-chapter Dragon Ball manga series created by Akira Toriyama, that were published from 1988 to 1995 in Weekly Shōnen Jump. Dragon Ball Z first aired in Japan from April 25, 1989 to January 31, 1996 on Fuji TV, before being dubbed in several territories around the world, including the United States, Australia, Europe, India, and Latin America. Dragon Ball Z details the continuing adventure of Goku as a young adult and father to his son Gohan. After learning he is a Saiyan, Goku dies and is revived after training in the afterlife under the god North Kaiō. Goku defends Earth from the Saiyans under Vegeta, and leaves Earth to ultimately defeat them again and the galactic tyrant Frieza. Three years later an evil life form called Cell holds a fighting tournament to decide the fate of the Earth. Goku sacrifices his own life and Gohan avenges his father by defeating Cell. Seven years later, Goku is revived and quickly drawn into a fight against a magical being named Majin Buu. After numerous battles, destruction and recreation of the Earth, Goku destroys Buu with the energy of everyone on Earth making a very powerful attack called "Spirit Bomb". Due to the success of the anime in America, the manga comprising Dragon Ball Z was released by Viz Media under the title Dragon Ball Z. Additional manga works, called animanga, were released which adapt the animation to manga form. Dragon Ball Z's popularity has spawned numerous releases which have come to represent the majority of content in the Dragon Ball universe; including 14 movies and 57 video games and a host of soundtracks stemming from this material. Dragon Ball Z remains a cultural icon through numerous adaptations, including a remastered broadcast as Dragon Ball Kai from 2009 to 2011 and from 2014 onwards.
