Ambush on Thanos

"Let's go get this son of a bitch."

- Captain America

The Ambush on Thanos was a successful attack on Titan II by the Avengers, who hoped to reverse the effects of the Decimation by retrieving the Infinity Stones from Thanos, not knowing that he had already destroyed them.

Background
"Even if there's a small chance that we can undo this, I mean, we owe it to everyone who is not in this room, to try." "If we do this, how do we know it's going to end any differently than it did before?" "Because before, you didn't have me."

- Black Widow, Bruce Banner and Captain Marvel

Three weeks after the Decimation, Thanos destroyed the Infinity Stones on Titan II, nearly killing him as a result. The usage of the Infinity Gauntlet was detected by the Avengers, who flew to avenge the victims of the Decimation on the Benatar.

Ambush
"What did you do?" "I aimed for the head."

- Captain America and Thor

Emerging from the Universal Neural Teleportation Network, Captain Marvel exited the Benatar and flew around Titan II taking reconnaissance, informing the other Avengers that there were no defences in place on the planet. On the planet's surface, Thanos prepared a stew to eat, picking crops from his farm. As he sat down in his hut, Captain Marvel burst into his home, placing him in a headlock. Bruce Banner in the Iron Man Armor: Mark XLIX quickly joined her, restraining the Infinity Gauntlet, with War Machine joining him by holding Thanos's other hand. Thor wielding Stormbreaker, sliced off Thanos's left arm, releasing the Gauntlet. However, to the Avengers' dismay, they learned that the Infinity Stones were destroyed. Filled with rage, Thor brutally decapitated Thanos, with the Avengers leaving the planet.
