The Attack on Greenwich Village was an attempt by Ebony Maw and Cull Obsidian, acting on orders from Thanos, to steal the Time Stone from the Masters of the Mystic Arts.
As Doctor Strange and Wong were about to leave the New York Sanctum, Bruce Banner crashed inside the place, having been brought there by Heimdall's bridge. After Banner told what happened during the Attack on the Statesman, Strange used his powers to bring in Tony Stark, who was discussing his future wedding with Pepper Potts.
Once Stark was brought up to date about the threat of Thanos and the Infinity Stones, the group realised that the android Vision, who had the Mind Stone embedded in his head, would be another target.
However, Stark explained that Vision had disappeared two weeks earlier, and that only the fugitive Captain America could possibly find him. Banner insisted that Stark call Rogers, only for Stark to explain to Banner that him and Rogers had fallen out as a result of the Avengers Civil War.
Banner continued to insist, and convinced Stark to call Rogers by telling him that Thanos had killed their teammate Thor. However, before Stark could place the call, they were interrupted by the sound of agitation in the streets and debris flying through the air.
Leaving the Sanctum to investigate, the four found people fleeing and screaming in panic, as a Q-Ship sent by Thanos had arrived, devastating the surrounding city with powerful winds.
From the inside of a Midtown School of Science and Technology bus leaving for a field trip, Peter Parker saw the Q-Ship from afar. While his friend Ned Leeds provided a distraction, Parker covertly left the vehicle and donned the Spider-Man Suit, swinging back to Manhattan to face the arriving invaders.
