The Pride The daughter of Dale and Stacey Yorkes, Gert is first seen straight up yelling that she does not want to go to the Wilders' annual supposed charity organization; after the witnessing of the murder of an innocent girl by their parents ("the Pride"), despite being shocked her parents are a part of it, Gert remains the only one not surprised that her parents are actually villains, saying that she had suspected her parents of being evil ever since her pet pig suspiciously disappeared. Gert joins her team in the mass ransack to escape from their respective homes. Before leaving, however, Gert discovers a dinosaur in a hidden room in her basement that has a telepathic bond with Gert's mind, meaning it obeys her every command. Later she and the other Runaways decide to use their real names again, but Old Lace continues with her codename, since she did not have any name before.
Personality Throughout the entire first volume, Gert refuses to answer to her given name and sticks with her codename the longest of all the Runaways, who begin dropping their names. After the battle, the government is forced to admit the Runaways are not murderers, but innocent victims. Gert is sent to live in a boarding school while the
Avengers detain Old Lace in a secret holding facility in LA itself. A few months later, she runs away from the school to join up with her friends and, with Chase's assistance, frees Old Lace. She joins the cadre in the Leapfrog, an old Pride land/sea transport also confiscated by the Avengers, and runs away to start life as a full-time
vigilante. Meanwhile, one of her parents' old time machines appears in the new Hostel carrying a black-haired, physically fit woman without glasses, claiming to be Gert from the future; this version of Gert grew up and became the leader of the Avengers under the alias Heroine. Heroine warns the Runaways of
Victor Mancha, a dormant teenage threat who will grow up to kill every hero under the alias "Victorious". The future Gert dies in Chase's arms without being able to finish saying, "I love you." Shortly after the Runaways' trip to
New York City, a new Pride reveals a kiss shared between Chase and Nico to Gert; Gert is distraught and the Runaways begin to deteriorate; Molly gets kidnapped and Old Lace physically attacks Nico. Gert and Nico are able to put aside their differences long enough to rescue Molly from the new Pride, but during the rescue, Gert takes a dagger in the stomach to save Chase. In her final moments, Gert transfers empathic control of Old Lace to Chase, ensuring the dinosaur would live. Gert dies in Chase's arms, having forgiven Chase for kissing Nico. Her last words, are her lamenting that the older version of her never told Chase how she felt, she then dies without finishing saying "I love you."
Home Schooling Arc Chase bumps into a girl bearing an uncanny resemblance to the late Gert, who does not recognize him. Initially stunned, he chases her to catch up to her, recklessly running through impending traffic. She yells for him to stop, as a silhouette resembling Old Lace appears in an alley behind her, but he is struck by a van. The girl apparently leaves as paramedics rush Chase to a hospital.
Resurrection Chase is eventually able to go back in time and rescue Gert from the moment of her death, taking her straight to Nico, who is able to save Gert's life through a rapid range of spells that include summoning a podiatrist (as the nearest doctor to Nico at the time) to treat Gert's injuries. Although she swiftly returns to her old bond with Old Lace, Gert is shaken to learn how the Runaways have fallen apart since her death, her words inspiring the team to come back together, rescuing Molly from her manipulative grandmother. ==Relationship with other Runaways==
