HISTORY: Cassie Lang was a fan of superheroes since she learned to read. Her mother abandoned her family when she was young and her father, electronics technician Scott Lang, turned to theft to support Cassie. At age 4, Cassie was taken in by her aunt and uncle when Scott was sentenced to 5 years in Ryker's Island Prison for burglary. Upon Scott's release, he was hired by Stark International and reconnected with his daughter, but when 9-year-old Cassie was diagnosed with a fatal congenital heart condition, Scott was forced to steal Dr. Henry Pym's Ant-Man equipment so that he could rescue Dr. Erica Sondheim, whose developments in critical focus laser surgery appeared to be Cassie's only hope for survival. Upon liberating Sondheim from Darren Cross of Cross Technological Enterprises, Scott saved Cassie and was allowed to keep Pym's Ant-Man equipment. Although Scott tried to conceal his super-hero identity from Cassie, she secretly knew he was Ant-Man. Living in a modest Nassau County suburb on New York's Long Island, Cassie spent her time making unique meals for her father and playing with other children of Stark International employees, such as Denise Pithins, the daughter of Human Relations Director Artemus Pithins. When Stark International fell into the hands of Obadiah Stane, Scott and Cassie relocated to Chula Vista, California, where Scott formed his own electronics company, Electrolang, Inc.

At age 11, Cassie moved back to New York when the Fantastic Four hired Scott for his technological expertise. Visiting the team's Four Freedoms Plaza, Cassie became attracted to Kristoff Vernard, a 12-year-old boy artificially implanted with Dr. Doom's memories and knowledge, although she was put off by his Doom-like armor. She eventually discovered that Zarrko the Tomorrow Man was impersonating Kristoff's man-servant Boris as a spy for the villain Hyperstorm, and she was imprisoned until the Fantastic Four defeated Zarrko. When the Fantastic Four seemingly died in battle, Scott was hired by Oracle, Inc. to join Heroes for Hire. Cassie accidentally reactivated and was absorbed by the Super-Adaptoid android in Oracle's basement, but Scott encouraged her to defeat the android from within. After Heroes for Hire disbanded, Scott became more involved with his longtime Avengers allies, and a family court judge awarded sole custody of Cassie to her mother (with Scott getting weekend visitations), citing concerns that Scott's activities would interfere with parenting. Sent to live with her mother and her new step-father, NYPD officer Blake Burdick, Cassie was abducted by killer Charles Cooley, but was soon rescued by Avengers Ant-Man and Jack of Hearts, who seemingly sacrificed his life to dispose of Cooley.

Cassie's life was forever altered when Scott died in an attack on Avengers Mansion by the deranged Scarlet Witch. Months later, at age 14, Cassie became affiliated with the adolescent heroes known as the Young Avengers and soon discovered she could alter her size as a result of exposure to Pym Particles she had stolen from her father over the years. Attracted to teammate Iron Lad (Nathaniel Richards), who soon left the group, Cassie adopted the codename "Stature" and assisted the Young Avengers against Kang the Conqueror, Mr. Hyde and Super-Skrull. Initially, Stature and the Young Avengers were affiliated with Captain America's rebel super-heroes, who were resisting the federal government's Superhuman Registration Act. After the events that ended Goliath's life, Stature has Joined Iron Man and the other heroes that registered with the government.

Cassie is unaware that her teammate the Vision (whose brain patterns are based on Iron Lad's) has a crush on her.

ABILITIES/ACCESSORIES: Stature can grow to gigantic heights, requiring the rapid acquisition of body mass (presumably from the Kosmos dimension). This extra mass fortifies all of her cellular tissue, including her bones and muscles, enabling her to support her increased weight and giving her superhuman strength. Stature can also reduce herself to a size of approximately one half inch.
