Delnald

Delnald is the family ship between Donald Duck and Della Duck from the DuckTales fandom.

Canon
Della, Donald, and their uncle Scrooge are daring adventurers. They have visited every place in the world, but Della wanted to go beyond the world. She had just had 3 triplet eggs that are about to hatch at any time, and she wanted to give them the stars. Donald thought it was reckless and irresponsible, especially with her boys on the line. Scrooge then decided to build a rocket ship anyways, and named it the Spear of Selene (after Selene, the Goddess of the Moon who Della is friends with). It was supposed to be a surprise for Della, but Della was always good at sniffing out secrets. She took the Spear of Selene, and flew off into space. Scrooge tried to talk her down from it, because a cosmic storm was happening. One of the meteors hit the spear, and Della was never heard from again...

Scrooge then spent billions and billions of dollars to build spaceships to look for her. Donald at the time was very angry and frustrated with his uncle for loosing his sister into space, so he took her 3 boys and raised them as his own when they hatched. Scrooge, on the other hand, spent too much money on rockets, that his board members literally had to pull him away. From that day on, Scrooge and Donald never talked to each other again, until Donald had to ask him to babysit the boys 10 years later.

Season 1
11 years after Donald lost his sister, and in the events of "Woo-oo!" when he needed Scrooge to look the boys, Donald and Scrooge spent the beginning of it were arguing. As Donald hadn't forgive his uncle for what happened to Della and wanted to make sure that Scrooge doesn't do anything to make history repeat itself with the boys. Much later in the treasure room, Scrooge and Donald had been arguing again, and it gets much worse when Donald references the Spear of Selene that Scrooge was responsible for. But Scrooge replies that he was not responsible for the incident.

In "The Last Crash of the Sunchaser!", when the boys returned home to Donald's fixed houseboat, the three give their uncle a straight angry face, to which has Donald asking why they look soo down. Dewey responds that they know about the Spear of Selene. Donald looks down sadly, and the boys storm off into the boat.

Season 2
In "Last Christmas!", Dewey goes back in time to spend Christmas with a young Della and Donald. Della wanted to go camping in the yard for Christmas, and she brought a family-sized tent and extra food. Why? She wanted to spend Christmas with her twin brother Donald, who instead played the guitar in his room. Della was miserable without him, and Donald admits that he felt bad for not spending Christmas with her. When everyone (in the present time) is spending Christmas together, it flashes back for a brief moment to them, and they are opening presents together by the tree.

The events of "Whatever Happened to Della Duck?" shows that Della has a "family room" that has a picture of her and Donald with Scrooge and her boys as eggs. In "The Golden Spear!", after sending Donald away on vacation, he accidentally stumbles on Della's rocket ship. He scans the ship for his sister, wanting to rescue her and see her again. Instead, Della had already escaped the rocket, and Donald accidentally turned it on. He was then shot right into space. When Della is exploring her brother's houseboat in "Nothing Can Stop Della Duck!", she finds many pictures of Donald with the boys. She says that he did a good job raising them, and that deserved the vacation he was on.

When Della and her boys come across a desert island in "Moonvasion!", they find Donald who had been stranded on it since he escape from space, like Della had before him. As Donald and Della were finally reunited with one another, after 11 long years.

Season 3
Throughout "Challenge of the Senior Woodchucks!", Della tries to tell Donald that nature isn't so bad, all while a mosquito keeps chasing him. While in "Lost Harp of Mervana!", Della is rambling about how fish and sea life is disgusting, she almost accidentally crashes the submarine. Donald stops her and drives the sub in her stead.

Fanon
There was a great desire for many to find out who the triplets mom was, and thus who Della was. There was a brief answer in some Don Rosa comics, but nothing was explored till the 2017 DuckTales series. Fans started to explore how the relationship between Donald and Della was as well. Though this was a challenge, given that her personality was never shown and many fic writers and fan artist had to come up with her personality on their own. More concrete exploration happened after "The Last Crash of the Sunchaser!" and the two were seen interacting. The overprotective relationship they have also leant to more people wanting to see them interacting.

When all the episodes showing Della on the moon were shown, more people started to ship them.

When "Moonvasion!" came, people shipped them more and more, given the fact that they reunited together.
