Origin

A polymorph of unknown origins, Lauren Wolfe was held at Project P.E.G.A.S.U.S. in New York. Unknown to her, she was one of the young, untapped superhumans one Nick Fury's secret Caterpillar List, which Fury used as a source of recruits for his Secret Warriors. Wolfe was freed from Project P.E.G.A.S.U.S., presumably along with another entry from the Caterpillar List Ahmed Noor, and drafted to join Team Black under the command of Alexander Pierce. 

Creation 

Lauren Wolfe was created by Jonathan Hickman and first illustrated by Alessandro Vitti in Secret Warriors. The character was first mentioned in the back matter of the first issue of Secret Warriors, which featured Nick Fury's list of Caterpillars. Wolfe did not actually appear until midway into the series, where Team Black appeared for one story arc. 

Major Story Arcs 

Last Ride of the Howling Commandos  

Lauren Wolfe and the rest of Team Black were deployed to take part in a joint attack on HYDRA's Hell's Heaven base in China along with the Howling Commandos PMC. The operation was a success with Team Black taking point on the infiltration of the base, allowing for a bomb to be detonated inside that reduced it all to burning rubble. With their mission complete, Team Black made their own separate exit from China apart from the Howling Commandos, not realizing that the Howling Commandos would suffer a devastating battle against HYDRA forces after they left. 

Wheels Within Wheels 

Having won his secret war against HYDRA and Leviathan, Nick Fury pulled together all of the surviving members of the Secret Warriors and Howling Commandos together into a new organization sponsored by the United Nations. This included Wolfe and the rest of Team Black, who now served in this organization under the overall command of Daisy Johnson.

Powers and Abilities

As a polymorph, Lauren Wolfe is capable of shape shifting. She utilizes this ability in combat by forming her hands into maces or other simple weaponry. The origin of her ability is unknown.
 
Presumably, Wolfe has received the same training in espionage and combat as other members of the Secret Warriors.
