Marvel ComicsAfter Frank Castle finally returns to his family home, we see the war veteran torch his former abode and leave many of his memories in a pile of smoke and dust. But before he does so, he smashes up a photo and takes a disc labelled Micro from behind it. The thing is, what exactly is Micro and how will it play into whatever we see from Castle next? In the comic book realm, David Linus Lieberman is somebody known as Microchip or simply Micro. For years, he assisted Frank by providing him with top-end technology, the latest weaponry, and also put his expert hacker skills to use. From we weve seen so far, it looks as if Micro could maybe be some sort of computer software as oppose to an actual person? Then again, the disc in question could maybe hold vital details on the actual person known as David Linus Lieberman. Regardless, it looks as if The Punisher is going to be getting some help wherever he lands next.
