When Scott Lang broke back into Hank Pym's house to return the suit, he was arrested, but escaped from jail with help from a horde of ants under Pym's control, including Ant-thony. Pym and Hope van Dyne trained Scott to ride on and control Ant-thony. Ant-thony accompanied Lang in stealing a device from the New Avengers Facility and assisted Lang in fighting and evading Falcon.
Scott Lang would again ride Ant-thony while infiltrating Cross Technologies. Flying alongside other carpenter ants, Lang and Ant-thony pursued Darren Cross up to the building's helipad as he made his escape. However, Cross fired upon the approaching swarm with a pistol, killing Ant-thony in the ensuing gunfire. This prompted Lang to swear revenge on Cross after landing on another carpenter ant below.
- Darren Cross/Yellowjacket † - Killer
- Ant-thony's designation number, 247, is a reference to the comics Tales to Astonish #27 and Marvel Premiere #47, the first appearances of Hank Pym and Scott Lang respectively.
- Although Scott Lang gave it a male name (Ant-thony) and called her "good boy", Ant-Thony was female.
Behind the Scenes
- According to Stanford biologist, Dr. Deborah Gordon, Ant-thony is portrayed in a manner that is not consistent with real world ants. It has the anatomy of a virgin queen ant, and thus would have to be a female, despite what Ant-Man calls it. Its behavior would be completely impossible, such as the ant phalanx scene, as carpenter queen ants do not attack together, and only stick with mates; and ants such as Ant-thony cannot be controlled in the manner the film portrays, since the duties carried out by ants are not instructed by any leader.
