Lennie was a criminal who came across Dick Grayson before he became Robin in Batman:The Animated Series.
He worked as a pimp in Gotham City's east side. He suspected his girl Chi-Chi was cheating on him and he figured out he was right. Before he could beat her up, Dick confronted him and fought the pimp. Lennie was last seen being imprisoned in a dumpster. He is voiced by Charles Howerton.
