Off-Canon Canon

“Off-Canon” Canon is any official (i.e., MTV-produced) Daria material that is incompatible with the depiction of the characters and setting of that series as reasonably realistic and internally consistent.

Fantasy Episodes
Though Daria was a fairly realistic animated show, certain episodes raised the ire of fans because their treatment of reality was regarded as cavalier. Five episodes in particular, from the third and fourth seasons, are often assumed by sticklers for "realistic canon" as events that never actually occurred. Some fanfic writers assume they were dreams, hallucinations brought on by a variety of ailments, or were fictional works created by one of the show's characters (usually Daria Morgendorffer).

“Depth Takes a Holiday”
This is the most notorious of the fantasy episodes, with the various holidays as teenagers wandering around Lawndale and interacting with Daria, Jane Lane, and others. However, some fantasy and science-fiction fanfic assume the dimensional wormhole in the back of the Chinese restaurant was real.

“Daria!”
A musical set during a hurricane? Again, most fanfic writers assume this did not actually occur.

“A Tree Grows in Lawndale”
The pink flower that sprouts from Kevin Thompson's "planted" crutch is a reality violation of the first order, though it does respond to the general theme in the episode about miracles occurring.

“The Lawndale File”
The presence of the government agents and some of the consequences (such as Anthony DeMartino being arrested) strike many as unrealistic. Artie's appearance on Sick, Sad World and the transformation of Daria and Jane into space babes was also an issue.

“Legends of the Mall”
The steel teeth of Metalmouth hanging on the door handle of Helen Morgendorffer's SUV at the show's end was a problem.
