Yeah, I was going to say Neelix is the Han Solo of Star Trek. Now, I'm going to go hang my head in shame for five minutes for having said that.
Harry Mudd has something in common too with Solo, being a smuggler, though Mudd is (or seems) much more unscrupulous.
In a Star Trek reboot, we might see Harry Mudd again, perhaps it will be a younger and perhaps slimmer Mudd, maybe one not as set in his ways or perhaps slightly more sympathetic. Though the character I think is closer to Boss Hogg from the Dukes of Hazzard, if anything.
