They are quite the force to reckon with. In my very early plans for City of Bears, I was going to write an entire arc about how Leather and Rubber take over their police precinct, but at this point, I think of the two of them mostly as vigilantes. As for their sense of justice–I still haven’t actually figured out what sorts of laws they’re enforcing!
What would even be illegal in a place like this? The thing which seems like the biggest crime is forcing a transformation on someone unwillingly, and yet I can’t see Leather and Rubber complaining much about that. It’s a bit of a sticking point for me, actually. Leather and Rubber can’t just go around changing whatever they’d like, they need to be held in place by some code of law, but what that code would look like is something I’m still exploring.
