Origin
Scott Lang was an electronics engineer who had difficulty supporting his wife, Peggy Rae, and daughter, Cassandra. Resorting to burglary he was imprisoned for three years. While in prison he studied electronics in greater detail and was hired by Stark International upon his release.  It was during his time in prison that his wife divorced him.

His daughter diagnosed with a serious congenital heart condition, Lang turned to Dr. Erica Sondheim for help.  When Dr. Sondheim was kidnapped by Darren Cross, president of Cross Technological Enterprises, to help correct his own heart condition, Lang burglarized the home of Dr. Henry Pym (Ant-Man I), stealing both the Ant-Man costume and shrinking gas canisters.

Lang rescued Dr. Sondheim, who in turn saved Cassandra's life.  Completing his mission, Lang returned the costume, but Pym, who had followed his exploits as Yellowjacket, insisted he keep the uniform and use it for the good of mankind as the world's smallest superhero, Ant-Man.
