[2] When the time-displaced Runaways landed in 1907, they meet twelve-year-old Klara, a girl of German descent[3] who had to live to serve her abusive middle-aged husband.

[citation needed] When her family discovered her powers, they married her off to someone moving to America (even though she was still a child), where she ran into the Runaways in 1907, who later brought her back to the present with them.

[5] Readers are first introduced to Klara after the Runaways helped to stop a fire in a factory full of children in New York City in the year 1907,[6] where they had become displaced due to a time device created by Gert's parents.

[7] After the fire is put out, Karolina flies through the factory looking for survivors and comes across a bridge of rose vines through a hole in the wall and catches a glimpse of Klara as she runs away.

When Molly asks if she'd like to join the team to get away from her abusive life, they are stunned to learn that it's not so easy for her, as the man Karolina saw was not her father, but her husband.

Klara gets scared and runs off after seeing Karolina and Xavin, in her female form, have an intimate moment, which she finds to be wrong due to her conservative upbringing.

[9] Klara later plays a vital role in the battle between the two teams and the Skrull known as Chrell, Xavin's former mentor and a powerful member of the invading army.

As the other Runaways, minus Xavin, are held in his clutches, Klara manages to cause a large tree to spring under Chrell's feet, wrapping him up and allowing the others to be freed, which turns the tide of the battle against him.

3) #11, the first issue written by Kathryn Immonen and drawn by Sara Pichelli, Chase, Nico, Victor and Karolina hold a house prom.

An outside source manages to send a UAV flying into the Runaways' Malibu home, in the upstairs living room where Klara and Old Lace lie.

Chase, in the downstairs living room, feels her die, as part of her connection to him, he huddles over apologizing to Gertrude Yorkes.

She screams for Old Lace's body to be taken away from her, and within minutes, the entire house is covered in long, twisted vines - Nico herself ends up almost strangled.

When she is panicked or upset, her control over her abilities suffers greatly, and this can result in her plants attacking anyone that approaches her, including her own friends.
