- Watching/Listening to some episodes of Atop The Fourth Wall, specifically the Halloween episodes.
- Playing Pokemon Pearl and Platinum simultaneously in The Underground to eventually catch Spiritomb.
- Having just ordered Pokemon Diamond, still considering my Sierra themed team.
I have:
Piplup:

(Adam from Ecoquest? Johnny Westland from Codename: ICEMAN? Torin from Torin's Passage?)
Shinx: Gabriel (Since the symbolic animal of the Ritters/Knights is a lion)
Budew: Laura Bow (referencing the second game where she wears a fancy dress)
Either Houndour or Eevee: The Hero (Quest for Glory, referencing the different classes. For Houndour, it could reference all three classes with it being Dark (Thief) and Fire (Magic User's Flame Dart) and having good Attack/Special Attack (Fighter AND Paladin with their powers linked to their mana). For Eevee, it could also represent one of the classes, Flareon and Jolteon (Magic User's Flame Dart or Lightning Ball), Umbreon (Thief), Glaceon (Magic User's Frostbite), Leafeon or Espeon (Fighter or Paladin)
Either Abra or Beldum: Doctor Brain (He IS smart!)
Either Aron, Farfetch'd (with good Nature), Lickitung, or Cranidos: Duke Garland (Zeliard's protagonist), Roger Wilco (Space Quest, since he's seen as a terrible janitor), Larry Laffer (Hey, you can use your tongue for lots of things to have fun, right?), or Roger again (since he's usually portrayed as not very smart)
