Attack on the Statesman

"Hear me, and rejoice! You have had the privilege, of being saved by the Great Titan. You may think this is suffering. No...it is salvation. The universal scales...tip toward balance because of your sacrifice. Smile...for even in death...you have become children of Thanos."

- Ebony Maw

The Attack on the Statesman was an attempt by Thanos and the Black Order to retrieve the Space Stone from Loki.

Background
"I wouldn't worry, brother. I feel like everything's gonna work out fine."

- Thor to Loki

To be added

Attack
"I assure you, brother - the sun will shine on us again!" "Your optimism is misplaced, Asgardian." "Well, for one thing, I'm not Asgardian. And for another, we have the Hulk."

- Loki and Thanos

When the Statesman was approached by the massive Sanctuary II, Thanos and the Black Order proceeded to board the ship and slaughter half of the population, the other half managing to escape, as the Sanctuary fired relentlessly at the ship. Thanos managed to grab a defeated Thor and threatened to remove his head with the Power Stone if Loki refused to give up the Tesseract. Although Loki seemed to not care over his brother's survival at first, he quickly changed his mind and gave Thanos the Tesseract, which he smashed open to find the Space Stone underneath and added it to his Infinity Gauntlet.

As Loki began to reassure Thor that they would survive the ordeal, he assured Thanos that they have the Hulk on their side, who immediately attacked the Great Titan. Although Thanos was quickly able to defeat Hulk, he was sent to Earth by Heimdall before Thanos could kill him, which turned out to be a fatal mistake as Thanos decided to kill him instead in retaliation. In an improvised attempt to assassinate Thanos, Loki pretended to worship him as he hid a knife behind his back, which also turned out to be a fatal mistake as Thanos saw the attack coming and stopped the knife from slicing his throat. In anger, Thanos held Loki up in the air and choked him to death, also snapping his neck, before tossing his corpse down to Thor. With his job now complete, Thanos used the Power Stone to blow up the ship and everyone on it before leaving.

Aftermath
"Thanos is coming."

- Bruce Banner

After being sent away by Heimdall, Hulk crash landed on Earth in the New York Sanctum and transformed back into Banner, where he met Doctor Strange and Wong, whom he warned about the impending threat of Thanos.

A distress signal sent out by the Asgardians during the attack was picked up by the Guardians of the Galaxy, who later checked up on the aftermath to find Thor, who turned out to survive the attack. He also warned the Guardians about Thanos.
