Walkyverse/YMMV

It's Walky!

Fan Nickname: The organization that Jason's father heads was never given an actual name. Fans eventually took to calling them the JFO (Jason's Father's Organization).
- The Head Alien was dubbed "Dexter" by fans after he died and was resurrected, which mirrors your body and thus switched his fingered hand from his left arm to his right. This was never seriously used in the comic, though it was was referenced during the Fans crossover.
  - In the Dumbing Of Age continuity there's a cartoon called Dexter, The Head Alien.
Magnificent Bastard: Head Alien, and in the final arc, Penny Worthington.
- And arguably Mike.
Mood Whiplash: Oh dear sweet lord, SO MUCH. Routinely switches from grief over main character deaths to Toilet Humor. Oddly, this can heighten the dramatic effects - the characters are so used to that sort of thing by the end of the comic that they move on faster than the reader does.
Wangst: Sal is especially prone to this, and it starts getting lampshaded early on. Jason finally had enough of it in this strip.

Flanderization: Carol (Joyce's mom) has become solely defined by the I Want Grandkids trope.
Fridge Horror: Head Alien II's monologue about how he was free to drift from dimension to dimension destroying SEMME over and over has a panel of dead agents drawn in the style of Willis's elementary-school work, implying that he pretty much wiped out that Lighter and Softer world. Holy crap.
