Black Panther holds a party to give the Avengers and their guests a formal introduction of Shuri until an attack by Atlantean soldiers led by Attuma's general Tiger Shark occurs. When Tiger Shark blows the Horn of Neptune, it summons a sea monster as Thor, Captain Marvel, and Ms. Marvel work to keep it from destroying the bridge.

Suspicious of Attuma following Tiger Shark's defeat, Black Panther and Shuri go on a dangerous mission to Atlantis. As Black Panther infiltrates the palace in order to get answers from an imprisoned Tiger Shark on why he was after a Wakandan crest, Shuri mingles with the diplomats where she runs into Wakanda's ambassador N'Jadaka who has a secret agenda that Black Panther and Attuma don't know about.
