If you made him a human in a game that would've fit him as a human, he would've been badass.
Not really. It definitely wouldn't have been as funny. Look, the point is, Shadow's past is kind of stupid. He's an genetics experiment that bonded with a child who got killed by the government. Thats incredibly unoriginal, and its not meaningful or interesting despite that because his past never serves as anything more than an excuse for Shadow to angst: Shadow doesn't really learn anything from it, and that makes any kind of moving past that feel completely contrived. The reason why badasses always have dark backstories are so they have demons to confront that contrast with any of their positive traits: Shadow never confronts his past, and doesn't really have any heroic qualities(by the time of his starring role), so why bother focusing on his past at all? How can such an exaggerated character, human or hog, be a basass?
And, now that I've gotten all that pretentiousness out of the way, I will say that watching him use a machine gun thrice his size is kind of cool.
