- Evil Is Sexy: Maya. She's pretty if you can get over the fact that she's Ax-Crazy.
- Fridge Logic: Cars are mentioned often as presently existing. If there's enough metal to build cars, how is there not enough for steel boats? And why is it that technology mentioned contrasts so badly with technology seen?)
- There are NO RANGED WEAPONS in the series, even though crossbows at least, and more likely pistols, should coexist with the pirate's level of technology. Especially since automobiles are present.
- Squick: Sidorio magically impregnating the twins' mother.
- Tear Jerker: Murphy. Just Murphy.
