Billy Lee (AKA Bimmy Lee) is one of the two main protagonists of Technōs' Double Dragon series of beat 'em up games. He is the younger twin brother, training partner and in some occasions even rival of Jimmy Lee. He is a master of Sou-Setsu-Ken, a legendary Chinese martial art which he mastered at a young age.
Billy is also the boyfriend of Marian, who is often captured by rival gangs (mainly the Shadow Warriors) in order to lure him and his brother to reveal the secrets of their fighting technique. He and Jimmy exchange blows over Marian and who gets to keep her often.
Michael Donovan plays Billy here (given the material of the show) as this honored student of the dragon code and whatnot rather than a street brawler. Not too dissimilar to his role as Guilt voicewise, he isn't incompetent at voicing Billy Lee. It's yet another performance where the actor has to make the most of a script that isn't entirely faithful to the video game.
Jeff Luke sounds like a parody of the Teenage Mutant Ninja Turtles, and overall just really cannot act. Couple that with some of the most obnoxious dialogue and he is just.. no.
Dan Avidan (the not so grump guy) plays a Billy where he is more calm and adjusted, with hummingbirds flying in his dojo. For a cameo, he's pretty fun but not as entertaining as Arin.
