"Mad Dog" Morgendorffer

Deceased father of Jake Morgendorffer. We do not know the real name of Jake’s father, only his grotesque nickname.

“Mad Dog” Morgendorffer does not appear in the ‘’Daria’’ show, but his legacy does in the form of Jake Morgendorffer, Daria and Quinn’s neurotic father. Mad Dog's presence is felt in many episodes in the series as Jake rants about his rage at the way his father treated him. The most telling line in the show on this issue probably comes in “Jake of Hearts,” when Jake tells Daria, “My father always had to point out how I was screwing up, and that screwed me up. I just want to make sure I never make you girls feel that way—less worthwhile or intelligent than your old man.” It appears Jake was successful in this endeavor, though the struggle with his past cost him dearly.

Military Man
It is generally accepted in Daria fanfic that "Mad Dog" was a career military man, and that he served in either WWII or Korea. (Involvement in the Korean War is most often seen because of the time issue.) He has been portrayed as both a front-line hero and a gung-ho noncom who suffered from his war experiences. While this is not the only view of Jake's father, it is the most widely used explanation for his bad reputation, resulting in Jake Morgendorffer's rants and Ruth Morgendorffer's complaints about him.

Richard Lobinske offers a rare sympathetic view of Jake’s father in “Chosin Fate,” the tenth story in the Falling into College series. While transcribing reporters’ audio recordings from the Korean War, Daria discovers taped interviews with one Corporal Nathan W. Morgendorffer, U.S.M.C, newly arrived at Inchon in 1950, then later recordings as the now-sergeant is being shipped home. Jake’s father was a survivor of the battle at Chosin Reservoir, consumed with hatred for the enemy and probably suffering from post-traumatic stress disorder. He has become bitter and vengeful, missing all the good qualities that earlier recordings with him revealed.

"Structure," by Angelinhel, reveals some slightly sympathetic insight into Mad Dog's reasons for sending his son to military school.

A True "Mad Dog"
Some fanfics explore dreadful possibilities for Jake's father as the worst of fathers and human beings.

"Where's Mary Sue When You Need Her?," by Scissors MacGillicutty, offers a shocking legacy from "Mad Dog" that threatens to destroy the Morgendorffer family.

"Mad Dog," by The Angst Guy, develops another treacherous hand-me-down from Jake's father, discovered by Daria in a trunk.
