The heart and soul of the Runaways, Gertrude "Gert" Yorkes uses her incredible intelligence, bravery, and no-nonsense attitude to galvanize a group of scared kids into a team of young heroes.
Aided by her telepathic connection to a genetically engineered dinosaur named Old Lace, Gert survived many encounters alongside her fellow Runaways, until the fateful day when a time-displaced Geoffrey Wilder murdered her. Rescued from the past by her boyfriend, Chase Stein, just moments before her death, Gert now finds herself trying to understand the world around her—including the new roles her friends seem intent on playing.
In the City of Angels
Gertrude Yorkes grew up a disaffected youth, not believing anything anyone (especially adults) told her and instead relying on herself and her own views of the world. And that was before discovering that her parents not only killed innocent people to harvest their souls, but also acted as time-traveling criminals.
Upon learning the truth about her parents, she immediately decided to run off with the children of the other Pride members to make a new life. But, there was one shocking discovery she made about her parents that she was happy about—they created a genetically-engineered dinosaur that Gert bonded with and found she was psychically linked to.
Though Gert does not possess any physical super powers of her own, she is an incredibly smart and clever young woman.
Her main ability, though, is her psychic connection with Old Lace, a dinosaur her parents genetically engineer in the 87th century to protect their daughter. She can also pass that connection on to others, which she does for both Alex Wilder and Chase Stein at various points.
