Draco in Leather Pants: Hank gets this treatment in-universe; he's the local pimp, he has a nasty temper, he's racist, he has no problem hitting women or animals, and he's pretty much just an all-around bastard, but he's pretty and every time he does something like keep a couple of drunk jerks from tormenting his illegitimate son, everyone goes "Awwwww! He really is a good guy!"
In a court case involving a woman defending herself against her abusive husband
Hank: He only hit her. Hell, I've done worse to my whores!
He's also seen literally throwing a rude customer out of his saloon, yelling, "NOBODY treats my girls like that!", implying that he's either mellowed or that the guy did something so despicable that even Hank was disgusted.
Replacement Scrappy: Very narrowly avoided when Daniel returned to town to help Mike search for the missing Sully. The plan was to kill off Sully (Joe Lando wanted to leave the show to spend more time with his family) and have Daniel as Mike's new love interest. Fans responded by flooding producers with a vehement "Save Our Sully" campaign, forcing them to amend their decision. Although Daniel did stay on as the new male lead, Sully survived his wounds but had considerably reduced screen time in order to accommodate Joe Lando's wishes.
