The brothers infrequently show an ability to sense when the other is in danger. Injury sustained by one is also taken by the other (although this ability is inconsistently shown) and if one has his powers deactivated by injury, so will the other. They usually transform out of those forms by crossing swords again and saying in unison "we are double dragons!", although several episodes show that heavy injury can deactivate their powers. In the series, Lee brothers are martial arts instructors and police consultants, who assume superheroic identities at moments of escalated violence.

Also, there was a feature film titled The Shield of Shadow Khan, which was conformed by three of Season 2's episodes: "Shadow Khan", "Shadow Claw" and "Doom Claw".

The story and characters of the animated series would be used in the Tradewest-produced Double Dragon V: The Shadow Falls, a Double Dragon fighting game released for home consoles. All of the characters introduced from the second episode and onward were original creations made for the show. By the end of the second episode, Abobo and Willy are sucked into the Shadow Mural, never to be seen again, while Billy and Jimmy join forces to fight against the series' true antagonist, the Shadow Master. Like in the game, Jimmy is revealed to be the Shadow Boss in this episode, with his henchmen being Abobo and Wild Willy, who were boss characters in the game as well. The plot of the pilot episode of the series is loosely based on the NES version of the first Double Dragon game. The futile search for their father, John Lee, was a subplot throughout the series. During the course of the series, the brothers recruited allies in their war against the Shadow Master (voiced by Jim Byrnes) and his henchmen. As a result, the Lee brothers oppose each other as adults, but Jimmy is betrayed by the Shadow Master and joins his brother as a " Dragon Warrior". The premise of the show had the protagonist brothers separated at birth, with Billy raised by an elderly martial arts master known as the Oldest Dragon, and his brother Jimmy raised by the evil Shadow Master as his second-in-command, the Shadow Boss.
