Jimmy Lee (ジミー・リー Jimī Rī?), originally known in the West by the localized nickname of "Spike", is one of the two main protagonists of Technōs' Double Dragon series of beat 'em up games. He is the twin brother, training partner and in some occasions even rival of Billy Lee. He is a master of Sou-Setsu-Ken, a legendary Chinese martial art which he mastered at a young age.
Despite their differences, he is always ready to tag along with his brother whenever trouble arises; more so if it involves a good fight. In more than one occasion he has fought Billy for the affections of their mutual friend, Marian.
While Jimmy is traditionally portrayed as a protagonist for most of the series, fighting evil alongside his twin brother, he has also been portrayed as an antagonist in a few notable works.
