Sometimes, other gods and goddesses make an appearance. Athena might show up to collaborate with Hephaestus on a project. Their interactions can add a lot of depth to the story. For example, they might have different ideas on how to create a new weapon, and their debates and compromises can be really interesting to read about. And of course, there could be a villainous god who tries to steal Hephaestus' secrets related to his snaps.
Well, Mikasa herself is obviously a main character in these fanfictions. Since it's about her snapping, she is at the center of the story most of the time. Eren is also often involved. Given their complex relationship in the original series, his actions or words could be the trigger for Mikasa to snap. Another character that might be involved is Armin. He could be the one who tries to calm Mikasa down or understand what made her snap.
Obi - Wan Kenobi is frequently in Anakin Snaps fanfiction. As Anakin's master, he has a big role to play. Their relationship is often explored, and Obi - Wan's reactions to Anakin's snapping are crucial. Sometimes he tries to bring Anakin back from the brink, while other times he might be the cause, albeit unintentionally, of Anakin's breakdown.
One interesting story could be about Hephaestus creating a magical snap device that has the power to teleport. It might involve a young apprentice who accidentally activates it and gets sent to a different realm. Then they have to work with Hephaestus to get back home.
In many Beast Boy Snaps fanfictions, the villain characters from the original Teen Titans series can also be main characters. For instance, Slade. His menacing presence and his constant attempts to undermine the Titans can create a lot of tension and conflict in the fanfiction. He might target Beast Boy specifically because of his unique powers, or try to use Beast Boy's 'snaps' to his advantage.
In some fanfictions, antagonists can also be important in relation to Naruto's mind snapping. For instance, Orochimaru might be interested in Naruto's new state. He could see it as an opportunity to either use Naruto for his own evil plans or study him to gain some new knowledge. So, the villains can have a significant role in the story of Naruto's mind snap.
Obviously, Butters is the main character. His friends like Stan, Kyle, and Kenny often show up in these fanfictions too. They might either be helping Butters with his snapping - related adventures or be the ones who are in trouble and need Butters to use his snapping powers to rescue them.
The dragon and the kyuubi are obviously the main characters. The dragon is often depicted as strong, with the ability to fly and breathe fire or other elements. The kyuubi, on the other hand, is known for its fox - like appearance and powerful magic, especially illusion - based magic.
