Nah man, never underestimate the crouching schmuck, hidden badass.
You can tell Cornbread is a badass just from how actively the story ignores her/paints her out to be unextraodinary. The buff guy, as little attention as he gets, is at least presentable, as is Potato Boy, but when you see a homeless guy/girl/-looking person, you can usually expect some form of hidden greatness from them, be it profound wisdom, unexpected fighting prowess or even high-tier connections.
Actually a really common trope, the somewhat unappealing, loser-ish/ignored type character being a badass in some way.
