Raised Catholic,[1] Liz feels that the fires are a result of her sins, and for a short time manages to keep them under control by a combination of prayer and force of will.
[2] After being juggled between extended family members following the death of her parents, Liz is taken in by the Bureau for Paranormal Research and Defense in May 1974, where she learns to control her power to some degree.
During the events of the story arc Wake the Devil, while searching for Giurescu's body, Liz leads a group composed of herself, Bud Waller, and Leach to the Ruins of Czege Castle.
[3] To learn how to better control her pyrokinesis, Liz lives with a society of monks in the Agartha Temple in the Ural Mountains before resuming active duty in the Bureau after Hellboy quits.
The dreams come to a height during the Killing Ground story arc, where Saa takes advantage of Ben Daimio's transformation to fully possess Liz and drive her into a coma until the ghost of Lobster Johnson appears and freed her.
Under the guidance of a mysterious aged man, she unleashes her full pyrokinetic powers, incinerating the Hollow Earth - and wipes out a combined frog/Hyperborean army gathered by the Black Flame.
The apocalyptic events plaguing the world came to a climax when the Black Flame, embittered and empowered by personal loss, managed to reach into the void and release one of the Ogdru Jahad, summoning it to Earth and binding it into his service.
Liz and Johann Kraus, recently empowered by a connection to an ancient source of cosmic power, were sent to deal with the Ogdru Jahad, with no tangible results.
Following the destruction of the Ogdru Jahad, Liz played an active role in the cleanup of the remaining threats wreaking havoc on the world and entered a romantic relationship with agent Ted Howards of the Bureau.
She was shown to have survived, however, encasing herself in a Hyperborean crystal prison and eventually being found by the descendants of Abraham Sapien that had come to inhabit the restored Earth in humankind's absence.
