Scott Edward Harris Lang is a former criminal who was convinced by Pym Technologies CEO Hank Pym to take up his mantle as the new Ant-Man. As Ant-Man, Lang fought against Darren Cross, Pym's protégé who became obsessed with Pym Particles and intended to recreate and sell the technology to terrorist organizations such as HYDRA and the Ten Rings. After his daughter, Cassie Lang, was taken hostage by Cross, Lang was able to send both of them into the Quantum Realm, where he saw Pym's wife Janet van Dyne, before successfully returning. Cross was presumably killed. Lang then began a romantic relationship with Pym's daughter, Hope van Dyne.
During the Avengers Civil War, Ant-Man fought alongside Captain America after being recruited by Falcon, whom he had previously met before defeating Cross. He was given a chance to back out, as what they would be doing would be outside the law, but scoffed as being a wanted man was nothing new to him. Lang was subsequently imprisoned on the Raft following the Clash of the Avengers before being freed by Captain America. He, along with Hawkeye, returned to a normal life by making a deal with Thaddeus Ross of the United Nations, which resulted in him being placed under house arrest.
Two years after the Clash of the Avengers, Lang remained under house arrest, spending much of his time playing with his daughter and learning magic tricks. One day near the end of his sentence, Lang received a dream from Janet van Dyne in which he saw a younger Hope. Lang notified Pym and Hope, who was on the run because of the Sokovia Accords. Hope, now having taken up the mantle of Wasp, broke Lang out of his home whilst successfully evading police detection, and took him to her father's portable lab. At Pym's lab, the three learned that Lang was quantumly entangled with Janet and that they had a limited amount of time to retrieve her from the Quantum Realm. Ava Starr, and Bill Foster, a former colleague of Pym's, sought to steal the lab, and use Janet's energy to heal Ava of her intangibility and pain. Sonny Burch, a criminal businessman also sought out the lab for its advanced technology. Together Lang and Hope were able to fight them off while Pym went into the Quantum Realm himself, successfully saving his wife. Upon her return, Janet was able to heal Ava. Lang finished his sentence and was no longer under house arrest.
Not long after, Lang arrived in Luis's van on a roof with a portable Quantum Realm portal for the Pym family to acquire a substance to help heal Ava. While he was in the Quantum Realm, Thanos succeeded in gaining all six Infinity Stones from the Avengers and the Guardians of the Galaxy, thus wiping out half of all life in the universe. During a countdown before his return, Pym and the van Dynes were all turned to dust, leaving Lang stranded in the Quantum Realm, though the world believed Lang was another victim of the Decimation.
Five years later, Lang came out of the Quantum Realm, having not aged a day. He sought out Captain America and the rest of the Avengers to suggest using the Quantum Realm to travel back to the past and undo the Decimation. Once Tony Stark figured out how to safely travel through time, Ant-Man alongside the Avengers went on a series of time heists to recover the Infinity Stones in the past. After which he fought with the rest of the Avengers and their allies against Thanos in the final battle. After the death of Thanos and his forces, Scott reunited with his daughter and Hope.
