"David Linus \"Microchip\" Lieberman (often known as Micro) is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Mike Baron and artist Klaus Janson, he first appeared in The Punisher #4 (Nov. 1987) as an ally of The Punisher for many years. He assisted the Punisher by building weapons, supplying technology and providing friendship, though in more recent publications, Microchip gradually evolved from the Punisher's friend to a bitter villain."@en .
