Attack on the Helicarrier/Avengers Assassinated

The Attack on the Helicarrier was an attempt by S.H.I.E.L.D. and the Avengers to retake the Helicarrier from Loki and his army.
==Background==
Seeking to avenge the death of his daughter, Hank Pym assumed the identity of the Yellowjacket and targeted S.H.I.E.L.D.. When Pym found out that Nick Fury was working on the Avengers Initiative, planning to bring together a group of remarkable individuals to fight the unconventional threats. Pym ultimately decided to kill all Initiative candidates, which resulted in the deaths of Tony Stark, Clint Barton, Bruce Banner, and Natasha Romanoff.
One of Pym's victims turned out to be Thor, the crown prince of Asgard. Thor's death resulted in Loki leading an army of Einherjar on Earth, seeking retribution for the death of his brother. 
Fury made a deal with Loki and promised that S.H.I.E.L.D. would find a culprit and hand them to Asgardians. Joining forces, Fury and Loki confronted Pym and defeated him, before he was apprehended by Einherjar. However, Loki turned against S.H.I.E.L.D. and ordered the Einherjar to conquer Earth for him, since the planet was unprotected. Fury eventually decided to relaunch the Avengers Initiative to combat the Asgardians' invasion, and recruited Captain America and Captain Marvel.What If...?: 1.03: What If...

S.H.I.E.L.D. and the Avengers confronted Loki and his army, however, it eventually resulted in Asgardians attacking the Helicarrier. While Captain America and S.H.I.E.L.D. agents were fighting the Einherjar on the ground, Captain Marvel assisted the Quinjets in the sky against the fleet of Asgardian Skiffs.
During the battle, The Watcher teleported Black Widow from the universe where Ultron destroyed the humanity to that universe. When Loki pinned down Nick Fury and attempted to enthrall him with the Scepter, Black Widow attacked Loki, much to the latter's shock since he was under the assumption that Black Widow was dead. Black Widow used the Scepter on Loki, neutralizing him, before joining S.H.I.E.L.D. and the Avengers in their fight against Asgardians.What If...?: 1.09: What If... The Watcher Broke His Oath?
