Nashuri

Namori is the het ship between Shuri and Namor from the Marvel Cinematic Universe fandom.

Black Panther: Wakanda Forever
They're first interaction was when Namor appeared before Shuri and Ramonda at the waters of Wakanda, praising the nation and asking why they revealed their country to the world. The actions of T'challa informing the world of Wakanda's true existence and their vibranium, countries have been trying to take it by force. Namor and his people encountered such people as they had a machine to go deep under water and track the precious metal.

Namor wants Wakanda to find the scientist and gives them a shell for them to use when they have the scientists and simply blow into it which he will answer. He threatens them that if they tell the world of his existence, he will wage war on Wakanda.

Shuri and Okoya tracked down the scientists, Riri Williams and plan to take her to Wakanda but are stopped by Namor's people from Talocan, Okoya is defeated and Shuri asks to be taken to see Namor before they can harm Riri Williams, which they accept. In Talocan Shuri is given a traditional piece of clothing to meet with Namor, who shares his backstory and motive for him wanting to kill Riri. Shuri tries to bargin with him by keeping Riri in Wakanda, and then offers herself when he turns it down, noting that she would love to see his nation. Namor tells her she can't in her dress, but they have suit she can use.

In the suit, Namour takes and shows Shuri his kingdom which she enjoys, smiling at the wildlife, colours and people, and is in wonder by the 'sun' he brought to his people. When returned and out of the suit, Namor and Shuri sit close together where he tells her that she is the first surface dweller to see Talocan, and gives her his mothers bracelet as a gift. There, they share a deep conversation about their nations and the people wanting vibranium. Namor makes it clear to Shuri that he wants an alliance with her and Wakanda and will allow the scientist if they wage war in the surface world, and if that doesn't happen then he will kill Riri and make Wakanda fall.

Shuri is distressed by this but can't answer him as he is being summoned, Namor tells Shuri that he heard her and her mother talking that night when he appeared, how she wanted to burn the world, and told her they can burn it together.

Shuri goes back to Riri where she wants to think about Namor's words, but Nakia breaks in and shoots dead one of the guards and manages to shoot the other holding Shuri hostage. Shuri wants to help and heal the guards wound, telling Nakia that this will bring a war, Nakia however doesn't listen and drags her away.

Shuri is not in Wakanda long before Namor and his people launch an attack, knocking down the ship she's in before going for Ramonda, where Namor throws water bombs through the glass. Ramonda manages to bring Riri back up and are dragged by Okoya and Nakia, both are not breathing. Shuri is held back as the two woman try to get Ramonda and Riri back, with Namor announcing that he will return in one weeks time with his entire army, He points at a distressed Shuri and tells her she is Queen now before leaving with his people.

After her mothers funeral and successfully recreating the heart-shaped herb, Shuri becomes the Black Panther and wages war on Namor in revenge for her mothers death. They bring the fight to the sea to lure him and his people out, with Shuri's plan, Riri manages to catch Namor by surprise for her ship to capture in, which Shuri gets in after. Inside she installed a heater so the water on Namor evaporated, making him weak. However Namor uses his spear, made of vibranium, to cause damage to the ship. Shuri orders her ship to be taken to the desert before fighting Namor, who quickly pushes her away and stabs his spear into the ship once more, causing it to be destroyed and Shuri landing on the sand.

They engage back into their fight where Shuri rips off one of Namor's wings on his ankles and knocks him down, however Namor finds a spear and stabs her with it, he tells her that it could have been different, before turning away and trying to get back to the water, limping along the way. Shuri manages to overcome the pain and takes the spear out, appearing before Namor, who takes a stance to fight. Shuri gives a voice command for Namor's back to be hit with little fire bombs, making him collapse and stay there.

Shuri kicks Namor onto his back and picks up a spear, holding the edge of it to his throat. She hesitates to kill him, she remembers everything that has happened since he came and her mother calls out to her, to show Namor who she truly is. Accepting this, Shuri lets go of her vengeance and tells Namor to yield, she won't tell the world about him and Talocan, she'll keep him in Wakandan borders and his people will live.

They go back to their people and tell them to stop fighting, the war is over.

Afterwards, Namora voices her concerns to Namor about Wakanda and Shuri, to which he tells her that Shuri had every motive to kill him but chose not to, that her empathy will help the alliance, and Wakanda will call on him when they need to.

Fanon
After the release of Black Panther: Wakanda Forever, the ship between Namor and Shuri sailed rapidly, with 65 works on Archive of Our Own in just days after it's release. The fans saw Namor's gentle side, having a dress made for her, dinner prepared for the two of them and giving Shuri his mother's bracelet as a sign of more than just an alliance, but more of a marriage proposal.

Marriage Alliance
Many fans have said that Namor's treatment towards Shuri (being gentle and giving her gifts) feels more like a marriage proposal. Given that Shuri is royalty, it is naturel to royals to marry for alliance and peace between lands, which many fans have use in fanfiction.

Hades & Persephone
Many fans have said the ship parallels Hades & Persephone, with Namor kidnapping Shuri (in this case Shuri asked to be taken to see Namor), showing her his kingdom, giving her gifts and being gentle with her. With Ramonda wanting Shuri (and Riri) back at any costs, it is natural she is Demeter.
