ObiDei

ObiDei is the slash ship between Deidara and Obito Uchiha from the Naruto fandom.

Canon
Deidara and Obito have their first scene together when Obito, under the identity of Tobi, finds his severed arm on the ground. They seem to have met before, since they both knew each other's name. Tobi, who believed that Deidara was dead, is happy to learn that he is still alive. After a brief argument, Deidara ends up strangling him with his legs, since he has no arms, and calls this technique "death by suffocation".

Since Sasori just died and Tobi finds his Akatsuki ring, he becomes Deidara's new partner. Deidara's attitude being with Sasori was more carefree and cheeky, but the dynamic with Tobi is completely different. Since now he is the senior and Tobi the rookie, Deidara shows a more mature attitude, becoming the leader of both. Tobi calls him senpai, an honorific used for people who have been belonging to a workplace or school for longer.

Although they seem to get along well, Tobi makes Deidara lose his patience often. He has the opinion that Tobi is a slacker who leaves all the work to him, pretending to be a beginner. On other occasions, Tobi angers him and Deidara ends up using his bombs, which he dodges.

When they go together to capture the Three Tails, Deidara and Tobi stop on the way to eat dango. Then Deidara tries to see his face to no avail, as Tobi, lifting his mask, turns to the opposite side so he can eat. After that they both argue again. Tobi makes him angry by saying that his art is a rip-off of a paper lamp in the shape of a pig that they find. Deidara blows up Tobi and walks away. When Tobi returns, he has stopped speaking to him and is trying his best to get Deidara to speak to him again. That's when Tobi says that he is "showing his ass but not his face" and that he is "a schoolgirl in love with his senpai". Deidara yells at him to leave him alone and Tobi replies that if he forgives him he will show him his face but that doesn't convince Deidara. Both continue towards the Tres Colas by separate paths.

Once at the lake, Deidara pushes Tobi into the water and tells him to capture it himself. Tobi fakes drowning and Deidara has to intervene, throwing bombs at the Three-Tails. He is eventually captured, but despite doing nothing, Tobi scores the victory for himself, much to Deidara's dismay.

As they both return to base, Deidara gives Tobi lessons on how to be cooler. He tells her that he talks too much to be a criminal. Tobi tells him that he talks too much too. After this, Tobi stays quiet and Deidara says that he doesn't have to stop talking either. Tobi is pretending to be asleep and talking in his sleep, which makes Deidara angry again.

In Deidara's fight against Sasuke, the two of them seem quite involved in the battle. It is revealed that they have a joint technique (The C-2 Dragon) and that Tobi knew many secrets about Deidara, which he had not told anyone else. Deidara shows concern for Tobi's safety in the fight, saving him on one occasion and telling him to back off. Still, when Deidara detonates his final artwork and is about to die, his last thought is of Tobi, thinking that he has killed him. Deidara apologizes and then explodes.

They meet again when Deidara is brought back with the Edo Tensei technique. They don't have any more dialogue together, but Deidara isn't surprised to see his former partner become the new leader of Akatsuki. Nor by learning that he is actually an Uchiha, which he hates.

They have a few more scenes in the Rock Lee's Springtime of Youth spin-off, where they both visit Konoha and befriend Rock Lee and Tenten. In one of the scenes, Deidara gives Tobi a tender look as he praises his art. In another scene Tobi makes up a story where a woman named Tobiko, clearly based on him, is in love with her co-worker Daradai, who is clearly based on Deidara.

Fanon
ObiDei's popularity has fluctuated over the years. At first they were known as TobiDei, or DeiTobi, as Tobi's true identity was only a theory. At one time, when Tobi revealed his identity as Madara, the ship was known as MadaDei. When Tobi's true identity as Obito came to light, the name became obsolete. Nowadays ObiDei is the most popular name.

The most common themes in ObiDei are those where Deidara gradually discovers Tobi's true identity, while Obito, through Tobi's bubbly persona, ends up becoming fond of Deidara despite his inner bitterness and hatred towards the world. In the past, themes of Deidara trying to get over Sasori's death, with Tobi comforting him were more common. During the time when Tobi was officially Madara, fanfic themes were darker in nature.

In ObiDei stories there is usually a lot of humor, due to the dynamics that Tobi and Deidara relationship has in canon.

The fandom has adopted a Boruto character named Sekki, as the son of Obito and Deidara. This is because the boy physically resembles both of them a bit, as well as having a personality and future plans (becoming Tsuchikage) almost identical to Obito's.

There's been a Tobidei Week celebrated every October since 2017.

ObiDei is especially popular in the Portuguese-Speaking fandom.
