Scott Lang
The second, and current, Ant-Man is Scott Lang. A former electronics genius turned criminal, Scott was forced back into a life of a crime when he needed to pay for an operation on his daughter. Coincendentally, the house Scott broke into was the house of the previous Ant-Man, Hank Pym. Stealing the Ant-Man costume and Pym Particles, Scott rescued the doctor needed to perform the operation, and was allowed to become the new Ant-Man, frequently helping out Iron Man and the Avengers. Scott has also been part of the Fantastic Four, the Heroes for Hire, and eventually, the Avengers. Unfortunately, it was during his term with the team that he was seemingly killed by a reborn Jack of Hearts exploding, until it was discovered that a future Scarlet Witch had teleported him to the future to save him. Following his return, he served a brief stint with the Defenders and is the current leader of the Future Foundation.

Eric O'Grady
The third Ant-Man was S.H.I.E.L.D. agent Eric O' Grady. Stealing an experimental Ant-Man armor from Hank Pym, Eric abused his position as a superhero for his own selfish gain. However, as time went on, he became less of an immoral jerk and more of a genuine superhero, even briefly serving in the Secret Avengers. He was killed by the Shadow Council.

Powers
Each incarnation of Ant-Man has been able to alter his height through the use of Pym Particles, and communicate with ants via their helmets. At their reduced heights, their molecular mass stays the same, granting them super strength. As Ant-Man, Scott developed special bracelets called "stingers", which fire electricity at enemies.
