In Graphic Fantasy, a self-published title by Larsen and two friends, The Dragon was a widower, with his wife Liz being shown in flashback in both issues.
Jennifer had married her high school sweetheart Kevin Murphy after they graduated and had a baby girl called Angel.
One night Jennifer strikes Kevin to defend Angel causing his head to explode due to the mutant powers she had developed.
In The Savage Dragon, Erik Larsen has the US Government proposition him about making a replacement team for Youngblood which he eventually forms from most of the series' super-powered/costumed support cast and names "Special Operations Strikeforce" (S.O.S).
Jennifer is one of the S.O.S members sent to Darkworld to stop its despot ruler Darklord from swapping his dying planet (later revealed as another Earth) with the S.O.S's.
Stuck on a dying planet, they were able to escape using a Martian space ship that was at the bottom of that world's Lake Michigan and the two spent months lost in space along with the Darkworld version of The Dragon's old girlfriend Debbie Harris eventually crashing on Godworld, where the offspring of the various Gods and Deities of mythology had been banished.
Eventually All-God (an all powerful 'god of gods') intervenes to send Jennifer and Dragon home where she is reunited with her daughter.
Her daughter Angel survived and was rescued by She-Dragon from Dimension X, where she fell shortly before the Earth was destroyed.
Glum is constantly trying to kill The Dragon or take over the world, though his plans always come to naught often with comical results.
Jennifer is eventually proved right when Ba-Goom comes into possession of the God Gun and takes over the planet with Angel at his side.
She was badly injured and hospitalized after an experiment of Glum's caused Angel to grow to gigantic proportions and destroy Jennifer and Dragon's house.
Before losing her powers she had super strength, enough to cause a man's head to explode on impact with the force of the punch.
