The AnimatedAdaptation of the ''VideoGame/DoubleDragon'' 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 [[NeverSayDie 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 [[AdaptationalVillainy as the final boss]] and [[DemotedToDragon Willy as his henchman]]), but the series deviates from Episode 2 and onward.
----

!!''Double Dragon'' includes examples of the following tropes:
* AndKnowingIsHalfTheBattle - Every episode, except for the first one, ended with a public service announcement featuring the heroes teaching some kind of moral to kids, as was standard with most animated shows at the time. The Season 1 [=PSAs=] were pretty generic in nature, being nothing more than redubbed scenes from the actual show, with most of them being used for more than one episode. On the other hand, the Season 2 [=PSAs=] were unique to each episode and had morals that were actually related to the episode's plot. One particularly ironic example is in "Virtual Reality Bytes", which centers around a kid's video game addiction. 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.
* ArmCannon: Triggerhappy. The figure of the character carries a {{BFG}} instead.
* BattleCry: Both, the Dragons and the Shadows, have one.
** "Dragons Go!"
** "The Shadow Falls!"
* BlindAndTheBeast: 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 "[[NeverSayDie eliminate]]" the girl, Jawbreaker rebels against the Shadow Warriors and rescues her.
* ByThePowerOfGrayskull: "For might!" "For right!"
* CanonForeigner
** Most of the Dragon Warriors (save for Billy and Jimmy themselves) and the Shadow Warriors (the gang exists in the games, but not this specific roster) 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.
* ChildSoldiers: Shadow Master hires a young street gang to use his new {{ray gun}}s to attack the Dragon Dojo.
* CoolCar: the Dragon Cruiser.
* ColorCodedSecretIdentity: For some reason, many of the civilian characters have trouble figuring out that the Lee brothers are actually the Double Dragons, despite the fact that they always carry their swords with them. There's actually not much difference between their civilian clothing and their Dragon Warrior alter-egos, save for the addition of masks, the lack of undershirts (exposing their birthmarks), and the different boots and gloves. Not to mention that Billy was already fighting crime with his birthmark exposed in the first episode.
* CriminalAmnesiac: 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.
* CutShort: 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 unmade third season.
* DarkestHour: 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.
* DragonsUpTheYinYang: In addition to the gratuitous dragon imagery from the game, the show added various 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[[/note]] instead of the spots.
* FamilyFriendlyFirearms: 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.
* FantasticDrug: Oblivion and RPM.
* FauxActionGirl: Marian goes from a DistressedDamsel 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 ActionGirl and is practically reduced to a background character by Season 2.
* GoingToGiveItMoreEnergy: How Shadow Master is defeated in "The Abyss".
* HeelFaceTurn: Jimmy Lee after the first episode, and in Season 2, Jawbreaker.
* InNameOnly: The Pilot makes a fair adaptation of the first NES game and even features bad guys from the game (namely Abobo and Machine Gun Willy), but the rest of the series deviates from the games completely.
* KidSidekick: Michael and most of the Junior Dragons.
* LukeIAmYourFather: When the brothers meet their mother, she reveals that the Shadow Master is her half-brother, [[CaptainObvious which makes him their uncle]].
* MasterOfDisguise: Sickle.
* MerchandiseDriven: When have you seen the Double Dragons drive cars, or wear magical dragon armor? Never? You should watch this show more!
* {{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).
* NeverSayDie
** 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.
* NextTierPowerUp: 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.
* NiceJobFixingItVillain: If not because Shadow Master ordered to kill Jimmy, he wouldn't have turned to the side of good.
* OutOfOrder: The Season 2 episodes were aired without regard to their actual continuity. Particularly notable with "RPM", the final episode aired, which clearly took place before Jawbreaker's HeelFaceTurn in "The Sight of Freedom". "Daj of the Undertown Dragons" was the last episode made in production order.
* PhantomZonePicture: If a villain [[YouHaveFailedMe screws up once too many]], the Shadow Master will make him part of his mural, [[AndIMustScream trapped as stone and half merged into the wall]]. Previous victims are still seen there.
* RayGun: Unlike most versions they are usually {{BFG}}s because the can't make them hand gun size. One episode averts this.
* RedOniBlueOni: Billy: blue, Jimmy: red. Their costumes even match.
* SchizoTech: A helicopter with an AI that is actually the spirit of a shattered sword.
* [[FiveBadBand Six Bad Band]]
** Shadow Master: BigBad
** Sickle: TheDragon
** Icepick: EvilGenius
** Trigger Happy and Jawbreaker: TheBrute
** Countdown: TheStarscream
** The Shadow Khan: SixthRangerTraitor
* SuspiciouslySimilarSubstitute: Triggerhappy seems to be this for Willy from Episode 2 onwards.
* ToylessToylineCharacter: Despite being a blatantly MerchandiseDriven 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.
* UnPerson: 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."
