Luberto is the slash ship between Luca Paguro and Alberto Scorfano from the Luca fandom.

Canon
At the beginning of the movie Alberto scares Luca since Alberto dressed in a diving suit that did not show if he was a human or a sea monster, Luca follows him to the surface, he comes out again with Alberto's help. Alberto teaches Luca to walk. They then introduce themselves and become friends, Alberto teaches Luca more things from the surface and the human things that he collected, Luca repairs one of those objects, Alberto shows Luca what is a vespa, despite saying several times that he had to leave because his parents did not know that he went to the surface and would be angry with him, Luca stays and helps Alberto build a vespa. Luca dreams of him and Alberto riding a vespa together. Eventually Luca's parents find out and when they tell him that he can't go to the surface again, Luca tells them about Alberto and states that the two of them always take care of each other, then his parents tell him that he will stay with his uncle Hugo in the deep part of the sea, Luca escapes and stays with Alberto.

Alberto tells Luca that they can go to town and adds that it could be full of vespas, Luca murmurs that it would be both their vespa and asks Alberto if he thinks they would survive there to which he replies that together they will achieve whatever and that each night they would go to a new place and sleep together below the “fish”, with no one telling them what to do and that they would be free, with each word Luca's eyes light up more, Alberto shows Luca a drawing he made of him and Luca in a vespa and the latter affirms that it is the best drawing he has seen in his life, they swim together and arrive the the human town of Portorosso, which is where the shipping started. They do almost everything together until Luca befriends Giulia, a human girl from Genova that only visits Portorosso in the summer. Alberto becomes jealous of Luca spending time with Giulia and got sick of it so he reveals to them that he is a sea monster, Luca betrays him by pretending he's scared and didn't know he was a sea monster.

Fanon
Shippers immediately started shipping Luca and Alberto even before the movie came out, many people compared another movie named Call Me By Your Name and Luca and found similarities between both films and their main characters. There is very limited fan-fiction about them, but it exists. There is more fanart than fanfiction, in fanart they usually portray them in their sea monster form or as humans, or hanging out together, sometimes with Giulia or even Massimo supporting them and their relationship
