Duel at the New Avengers Facility

"Who the hell are you?" "I'm Ant-Man."

- Sam Wilson and Scott Lang

The Duel at New Avengers Facility was a confrontation between Ant-Man and Falcon caused by Hank Pym.

Background
Preparing the robbery of Yellowjacket Suit from Darren Cross, Hank Pym, Hope van Dyne and Scott Lang planned to visit one of the warehouses owned by Howard Stark. Upon arriving they discovered that after the Battle of Sokovia this warehouse was rebuilt, and became the New Avengers Facility.

Sam Wilson was recruited by Captain America to be a member of the Avengers; the New Avengers Facility is the Avengers' training facility.

Battle
"It's really important Cap doesn't find out about this."

- Falcon

As Scott Lang arrives at the facility, he rips at Hank Pym for not mentioning that the warehouse is the New Avengers Facility. As he stays ant-sized, Falcon arrives, having detected an unknown signal on the perimeter. Lang returns to normal size and introduces himself hoping to maybe get Falcon's help, only for Falcon to attempt to detain him. Lang shrinks and maneuvers around the open ground, changing size while fighting Wilson and dodging his gunfire. Ant-Man lures Falcon into the storage bay, successfully shrinks the device he wanted, and makes his way into the wiring of the flight pack of the EXO-7 Falcon to ground Falcon. Ant-Man gets away and Wilson radios the base not to tell Captain America about his defeat to a shrinking man.

Aftermath
"There was this dude looking for you; he works for the Avengers!" "Oh, shi--"

- Luis and Scott Lang

Ant-Man used the device to help in his battle with Darren Cross. Word even got around to HYDRA about the benefits of shrinking technology against an Avenger.

Falcon was impressed with the skill demonstrated by Ant-Man and sought to have him among the Avengers. Luis, a friend of Scott Lang, told Lang that Falcon wanted him.

When Falcon and Captain America encountered Winter Soldier, Falcon suggested the presence of Ant-Man for assistance.
