Papa Wolf - Go ahead, threaten Skeeve in front of him. Or, you know, don't.
Parental Neglect - He admits to Skeeve that he mostly left his kids' upbringing to other people.
The Reptilians - Scaled, green, short, and strong as all get out, with pointed ears. Unlike typical Lizard Folk, he's also very, very intelligent and used to be a great magician. (And, you know, a hero.)
Badass Normal: Unfortunately, they hang out with so many Trolls, Pervects, and hyper-competent assassins and magicians that they tend to be overshadowed a lot.
The Mafia: These two are lighthearted and occasionally subverted stereotypes of the trope.
Dropped a Bridge on Him: Poor Roddy might have had a long and prosperous reign. But he died mysteriously and with very convenient timing. As it happens, he really did die mysteriously with convenient timing... of natural causes.
