David Linus "Microchip" Lieberman (often known as Micro) is a fictional character appearing in American comic books published by Marvel Comics. He was an ally of The Punisher for many years and assisted the Punisher by building weapons, supplying technology, hacking into computers, and providing friendship. Microchip gradually evolved from the Punisher's friend to a bitter enemy after their final falling out. Micro was portrayed by Wayne Knight in 2008's Punisher: War Zone and by Ebon Moss-Bachrach in the television adaption of the first season set in the Marvel Cinematic Universe. Publication history Microchip first appeared in The Punisher vol. 2 #4 (Nov. 1987) and was created by Mike Baron and Klaus Janson. The character was inspired by Q from the James Bond series of novels and films. Fictional character biography David Linus "Microchip" Lieberman was a legendary computer hacker in the early days of the Internet, performing numerous scams and hacks still held in awe by his peers, until one scam brought him too close to real-world criminals and he was forced into "retirement", rebuilding his life as a quiet, unassuming businessman. This ended when his nephew, attempting to follow in his favorite uncle's footsteps, was caught and killed after accidentally hacking into the private computers of the Kingpin. While personally investigating his nephew's murder, Lieberman met and started collaborating with the Punisher. Microchip's help proved invaluable to Castle: he served not just as a hacker and cyber-investigator, but provided him with invaluable services, such as managing and laundering his finances (i.e., the money Castle takes from the criminals he kills), establishing and maintaining Castle's safehouses, helping Castle train in more "specialized" skills for his war on crime, and obtaining hard-to-get ammunition and equipment. Less obsessed with Castle's personal war, Microchip also acts as a de facto counselor to Castle (e.g., encouraging Castle to take occasional vacations and breaks, to avoid burn-out or losing his mind). Over time, more of his past history is revealed. His father had been forced to create weapons against his will years before Micro was born; in the same issue he mentions his sister is a happy housewife in Ft. Lauderdale. Micro has an illegitimate son named Louis Frohike, who winds up getting killed while trying to assist the Punisher in a hostage exchange. Micro is capable of fighting on his own such as when he took on an assassination ring threatening his godson's
