ANT-MAN (SCOTT LANG)

Since the Scott Lang version of Ant-Man was a regular supporting character during my second of Iron Man, I thought it would be fun to create a new design for him this month. I wanted to do something with the helmet to make it a little more high-tech while keeping the basic configuration similar to the original.

Scott Lang was born in Coral Gables, Florida. He turned to burglary when his occupation as an electronics expert failed to support his family. Apprehended, he served his prison sentence and was paroled after three years for good behavior.
In prison, Lang furthered his study of electronics and was soon hired by Stark International to work in its design department. Under Stark's direction, he helped install a new security system in Avengers Mansion. When his daughter Cassie became seriously ill, Lang decided to return to burglary as a final resort.
He broke into the home of Dr. Henry Pym and stole his Ant-Man uniform and shrinking gas canisters. Garbed as Ant-Man, Lang broke into Cross Technological Enterprises and discovered that Dr. Erica Sondheim, the only person capable of helping his daughter, was being held prisoner. He rescued the doctor and was relieved when Sondheim was able to save the life of his beloved Cassie.
Lang had intended to return the Ant-Man costume to Pym and turn himself in for its theft but Pym, aware of the use to which Lang had put the stolen goods, offered to let him keep them, provided he only use them to uphold the law.
Shortly after, Lang donned the Ant-Man costume on various occasions, primarily to assist Iron Man and the Avengers. As Lang, he aided Iron Man and Jim Rhodes against the Mauler. Scott was instrumental in helping Iron Man discover who possessed copies of his technology during the Armor Wars.
Using a gaseous form of "Pym particles" kept in a compartment in his belt, Ant-Man had the power to shrink himself (and other people and objects along with himself) to the size of an ant and return to normal. His cybernetic helmet allowed rudimentary telepathic communication with insects, and was equipped with sound amplification equipment allowing normal-sized humans to hear him. The helmet also had a retractable plexiglass face shield and a limited air supply. When wearing the suit, he can lift more than 4 times his weight. Scott required exposure to the "reducing gas" and "enlarging gas" in order to change size. "Pym particles" were created by the original Ant-Man, Dr. Hank Pym.
Scott could also shrink to sub-microscopic size, and thereby enter the countless "subatomic universes".
He has advanced training and expertise in electronics, and has earned an electronics technician certificate, plus additional advanced electronics training while in prison.
