The Battle at the Oui was a three-sided conflict between the combined forces of Ant-Man and Wasp, Sonny Burch and Ghost, started when Burch attempted to blackmail Hope van Dyne.


As Hope van Dyne and Hank Pym were building a tunnel to the Quantum Realm, Hope arranged to buy a part from the black market dealer Sonny Burch.

The meeting was set for Burch's restaurant Oui, with Pym and Scott Lang accompanying the events from the outside through the surveillance devices in the Wasp Suit.
