She was created by author Brian K. Vaughan and artist Adrian Alphona, and debuted in Runaways #1 with most of the other main characters.

[2] Like every member of the original Runaways, she is the child of evil villains with special abilities; in her case, time-travellers.

[4] Gert Yorkes was portrayed by Ariela Barer in the Hulu Marvel Cinematic Universe television series Runaways.

Though all the Runaways share a mutual distrust of adults, Gert remains the most fervent and vocal about the philosophy.

Gert is sent to live in a boarding school while the Avengers detain Old Lace in a secret holding facility in LA itself.

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.

Heroine warns the Runaways of Victor Mancha, a dormant teenage threat who will grow up to kill every hero under the alias "Victorious".

In her final moments, Gert transfers empathic control of Old Lace to Chase, ensuring the dinosaur would live.

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.

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.

[8] Their relationship was often defined by bickering - Chase's dim-witted moments often clashed with Gert's sarcastic and intelligent quips.

Their relationship developed quickly, with a few off-hand comments suggesting that they shared the same bed and were sexually intimate.

She revealed her insecurity about her appearance and fear that Chase would eventually leave her for a more conventionally pretty girl.

[3] Though implying she was hurt beyond reconciliation, she still ran into a burning building to save Chase from Geoffrey Wilder after their falling out.

[5] Gert's telepathic bond to Old Lace allowed her to directly communicate with the dinosaur and command it to do anything she wished.

While Marvel Handbook files have indeed given her intelligence levels a rating of 4 out of 7, and thus reasonably higher than the average mind, equal to Alex or even Victor Mancha's, she was not quite a genius.
