[In the final fight for the Nano Gauntlet with the Infinity Stones, Captain Marvel blasts at Thanos, who pulls the Power Stone out of the Gauntlet and uses it in his free hand to hit Captain Marvel away. Iron Man looks at Dr. Strange, who simply raises one finger, reminding him that the one win over Thanos he foresaw is now at risk. As Iron Man nods, Thanos puts the Power Stone back into the Gauntlet, channeling the powers of the Stones. Iron Man attacks Thanos, pulling on the Gauntlet before Thanos punches him away]

Thanos

I am… inevitable. [snaps his fingers, but nothing happens except a metallic clink. Looking confused, he turns the Gauntlet around to find the Stones gone, then sees Iron Man with the Stones on the back hand on his suit, looking wide-eyed]

And I... am... Iron Man. [snaps his fingers]
[Elsewhere, Rocket fires at a Leviathan, then takes cover as it crumbles into ash, just as it devours him. The Black Order and Thanos's army start crumbling to ash. Black Panther and Star-Lord look around in surprise. Cap looks on in exhaustion, knowing that they won. In horror, Thanos looks around as he watches his entire army disintegrate. He looks at Cap, who just stares at him. Thanos sits down, and mourns the loss of his army, then his body turns to ash as the remains drift away in the breeze]
