Cat. Eventually, he became the second Future Foundation's leader replacing Reed Richards when the Fantastic Four went on a time travel trip. Still suffering from his daughter's death, he decided to aim all the Foundation's resources towards making Doctor Doom pay for his crime; in the meantime he engaged in a romantic relationship with Darla Deering, aka Ms. Thing. It is to Darla that Scott confessed that he killed a fellow in-mate while in prison. After a heated battle, Scott managed to exact his revenge on Doctor Doom by gradually overwhelming and defeating him, and by having him believe he had killed Valeria Richards. He also determined the true meaning of Pym Particles, and how they operate on three distinct axes determining size, strength and durability. During the "AXIS" storyline, a now-heroic and repentant Doctor Doom used Scarlet Witch's powers to resurrect Cassandra Lang, seeking to atone for at least one of his crimes; she turned out alive and well on Scott's doorstep. Following this, Lang moved to Miami to start a new life as well as to spend more time with his daughter. Scott later established Ant-Man Security Solutions. When he was attacked by Grizzly, mistaking him for Eric O'Grady unaware of the latter's death, Scott had to clear up the misunderstanding. Afterwards, Scott offered Grizzly a job in the company. When Cassie was kidnapped by Crossfire on behalf of Augustine Cross to use Cassie's Pym-particle irradiated heart could revive the very first villain Scott had fought, Scott was forced to turn to Grizzly and his fellow supervillain Machinesmith to infiltrate Cross' plant to save his daughter. With Machinesmith disabling all the security Scott was able to get into Cross Technologies and fight his way to Darren Cross, whom Dr. Sondheim was blackmailed into reviving using Cassie's heart. Darren engaged in combat against Ant-Man while the hero tried to buy time for Sondheim to transplant another heart into Cassie. After Cross was forced to flee when the Pym Particles now in his body caused him to shrink down, Scott shrank down to microscopic size, and was guided by Sondheim to attack Cassie's white cells and allow her body accept the new heart's tissue. Even though the procedure was difficult, Scott was finally able to help Cassie survive the experience. When Peggy and Blake arrived, Sondheim told her that Cassie suffered an infraction and Scott took them to her. Although
