The Animated Adaptation of the Double Dragon video game series. It lasted for 26 episodes, running from 1993 to 1994.Billy Lee was raised and trained by the master of the Dragon Dojo. His main precepts are not to harm others intentionally and not fight if he can help it. When the master is gone, Billy becomes the new Dragon Master. He helps officer Marian Martin against the Shadow Warriors, a criminal syndicate led by the Shadow Master, wielder of the power of the Black Flame. Billy discovers that the Shadow Master's second-in-command, the Shadow Boss, is none other than his long-lost twin brother Jimmy. But when the Shadow Master betrays Jimmy, the brothers join forces in the fight against the Shadow Warriors.The first episode makes a fair adaptation of the first game (at least the NES version, which had Jimmy as the final boss and Willy as his henchman), but the series deviates from Episode 2 and onward.
Double Dragon includes examples of the following tropes:
And Knowing Is Half the Battle - Both seasons featured a public service announcement at the end of every episode (except for the pilot), but the ones in Season 1 were rather generic (consisting almost entirely of redubbed footage) and some were even shown more than once in different episodes. On the other hand, the PSAs in Season 2 were unique to each episode and were somehow tied to the episode's plot. One particularly ironic example was an early Season 2 episode about a kid who was really into video games. The moral was essentially "don't play the videogames all the damn time"—which, while certainly a good moral, is kind of odd coming from an adaptation of a video game.
Arm Cannon: Triggerhappy. The figure of the character carries a BFG instead.
Battle Cry: Both, the Dragons and the Shadows, have one.
"The Shadow Falls!"
Blind and the Beast: Jawbreaker befriends Samantha (Commissioner Briggs' blind daughter) after kidnapping her under the Shadow Master's orders in "The Sight of Freedom". When Icepick orders him to "eliminate" the girl, Jawbreaker rebels against the Shadow Warriors and rescues her.
Most of the Dragon Warriors (save for Billy and Jimmy themselves) and the Shadow Warriors (the gang exists in the games, but not these specific members) were created specifically for the cartoon. Granted, the Shadow Master appears to be loosely based on the nameless final boss from the second NES game.
The Shadow Falls fighting game featured a few additional Shadow Warriors who were not in the show. Namely Dominique, Bones, Blade and Sekka.
Color-Coded Secret Identity: For some reason, many characters have trouble figuring out that Billy and Jimmy were actually the Double Dragons, despite the fact that they always carry their swords. There's not even that much difference between their civilian clothing and their Dragon Warrior alter-egos, save for the addition of masks, lack of undershirts (exposing their birthmarks) and different boots and gloves. Not to mention that Billy was already fighting crime with his birthmark exposed in the first episode.
Criminal Amnesiac: Billy becomes the Shadow Boss this way in "Over the Line". However, he recovers at the end of the episode, while Jimmy's former career as Shadow Boss was almost his whole young life.
Cut Short: The Lee brothers never get to defeat the Shadow Master, nor do they ever find their missing father. "Daj of the Undertown Dragons" ends with a sequel hook for an unproduced third season.
Darkest Hour: In "The Abyss". Billy and Jimmy are stranded in the other-dimensional abyss, the Dragon Warriors are trapped in the Shadow Mural, and Shadow Master uses the EMF plant to energize the Black Flame and become all-powerful.
Dragons Up the Yin Yang: In addition to the gratuitous dragon imagery from the game, the show added various gratuitous dragon-themed accessories, such as masks, tattoos, and medallions. A good example would be the Shadow Warriors' insignia, a Yin-Yang with dragons note that look like an S in distant shots instead of the spots.
Family-Friendly Firearms: The Lee Brothers' magic swords, that shoot a green flame. Shadow Master has a scythe (that can split into a smaller scythe and a sword) that shoots a black flame.
Faux Action Girl: Marian goes from a Distressed Damsel in the games to a police officer in the TV series. Despite this, she doesn't really do that much to make her into a genuine Action Girl and is practically reduced to a background character by Season 2.
Mooks: The generic Shadow Warriors all wore metal mouthplates and were armed with claws. Blade from the tie-in fighting game was essentially one of them (along with Sekka, who was a one-of-a-kind female counterpart).
The Oldest Dragon is just told to be "gone", while Abobo and Willy are imprisoned forever in a magic wall by the Shadow Master due to their failure.
Averted in some subsequent episodes. In "Mistress of Chi", Jimmy asks Su Lien (the titular "mistress") if she killed the Shadow Master she uses her powers to teleport him, while the "Price of Oblivion" explicitly mentions the increasing murder rate that occurred in Metro City due to the sale of a new drug.
Next Tiwer Power Up: In Season 2, both the Lee brothers and the Shadow Master obtain magic armor in the form of the Dragon Claw Daggers for the Lees and the Shield of the Shadow Khan for Shadow Master. Later, they get "ultimate forms" as well.
Out of Order: Most of the episodes were aired without regard to their production order, especially during Season 2. Particularly notable with "RPM", the final new episode aired, which clearly took place before Jawbreaker's Heel-Face Turn in "The Sight of Freedom". "Daj of the Undertown Dragons" was the last episode made in production order.
Talking to Himself: Michael Donovan and Scott McNeil voiced the Lee Brothers, as well as the villains Jawbreaker and Sickle respectively. Some of the other characters also shared voice actors.
Toyless Toyline Character: Despite being a blatantly Merchandise-Driven show, the only characters to get tie-in action figures besides the Lee brothers and the Shadow Master were Vortex, Blaster, Sickle and Trigger Happy, rendering everyone else into this.
Un-Person: the Shadow Master intends to destroy the Dragon Dojo (the Dragon Warriors have been banished to the Shadow Mural, and the Lees are in another dimension), saying that once it occurs, "it will be as though (the Double Dragons) never existed."
