In fridget fanfiction, a friendly dragon could be paired with Fridget. The dragon can be a powerful ally, with the ability to fly long distances and breathe fire to protect them. A curious gnome might also be a good match. The gnome is very good at making things and could create useful tools for Fridget. Additionally, a mermaid could be paired with Fridget if there is a part of the story that involves water. The mermaid can swim fast and communicate with underwater creatures, adding a whole new dimension to their adventures.
A little fairy character could be paired with Fridget. The fairy could bring magic and flight abilities to their adventures. Another could be a brave mouse. The mouse would be small but very clever and could help Fridget get into small spaces or find hidden things.
One idea could be that Fridget is on a quest to find a magical object that can save its home from a mysterious dark force. Another could be Fridget making an unexpected friendship with a character from a different world. Maybe Fridget discovers a hidden power within itself and has to learn how to control it to face a great challenge.
One character could be a young wizard named Oliver. He could team up with Amanda Butterfly and use his magic to complement her natural abilities. Another option is a forest nymph named Lily.

In a Naruto fanfiction, Orochimaru could be paired with the Sandaime in a more complex way. Not just as an enemy, but perhaps in a story where the Sandaime tries to redeem Orochimaru. Another character would be Minato. Even though they were from different generations, they both had a connection to Konoha's leadership. You could write about how the Sandaime influenced Minato or vice versa. And Iruka could also be paired with the Sandaime. Iruka is a teacher, and the Sandaime was also very much involved in the education and growth of the shinobi in Konoha. So, a story about how the Sandaime and Iruka work together to improve the academy or deal with problem students could be really interesting.
One possible character to pair with Charlie Kanaalaq could be a wise old mentor figure. This person could guide Charlie through his adventures and help him make important decisions.

And don't forget the Lone Wanderer, who might be drawn into the Black Queen's orbit and become an important part of her story.
One character often paired with Tyrian could be Cinder. Since they are both villains in RWBY, they might be grouped together in fanfiction to carry out some devious plans. Their combined powers and personalities can create some interesting dynamics.
Princess Peach is often paired with Dark Mario in fanfiction. Their relationship can be very different from the normal one.
