Lee is a CPU character in Street Fighter. Though unplayable in the base game, he can be played via a code in SF1++. Though he has not made any appearances in the Street Fighter series outside of the original, his influence has taken effect in the form of Yun and Yang from the Street Fighter III series, who are his nephews.
Lee is a strong character that focuses on staying midrange and poking with his long ranged moves. Though he has powerful offense and good moves, he struggles up close as he doesn't have very good options and can be easily pressured at close range, so he prefers to stay out of it. He is also the only character besides Adon to have an "omni block" that allows him to avoid all moves, even unblockables.
In SF1++, Lee is selected by holding 
at the title screen or VS. Screen and pressing Start.
