Candace's friends from school or other family members could be in the fanfiction. For instance, her grandparents might show up and offer some wisdom or a different view on her situation. And if the story takes a more fantastical turn, there could be magical creatures or time - traveling beings that interact with Candace as she goes through this phase of having finally snapped.
The parents, Linda and Lawrence, would probably be important characters. Since Candace has snapped, their reactions to her new behavior would be a key part of the story. There could also be some new characters introduced, like a mysterious mentor who helps Candace come up with her plans or a bully who takes advantage of her new - found 'edge'.
Perhaps in this fanfiction, Candace finally snapped after years of being dismissed by her parents. She decides to run away from home to prove a point.

The real story of Candace Flynn is that she is a character from the animated series 'Phineas and Ferb'. She is the older sister of Phineas and Ferb.

This forms the comical and ongoing plotline in the show.
Obviously Tsuna would be the main character. His friends like Gokudera and Yamamoto are likely to be in it too. They might be the ones who are shocked by Tsuna's snapping and try to help him get back to normal. Reborn could also be there as he has been guiding Tsuna all along and would surely play a role in this situation, either trying to understand what made Tsuna snap or trying to fix it.
Perhaps in this 'natsu finally snapped fanfiction', Natsu snaps due to some dark magic influence.

It could lead to a big fight within the guild, with everyone trying to figure out how to save Natsu from this dark state.
Voldemort would still be a major character. After all, he is Harry's main antagonist. If Harry snaps, it would likely be in relation to his ongoing battle with Voldemort. And the Death Eaters, as Voldemort's followers, would also be involved. They would be on the receiving end of Harry's new, more aggressive stance, and their reactions would shape the story further.
Maybe it's a fellow guild member who has made a series of bad decisions. Their actions keep putting the guild in danger, and Natsu has been warning them. But when the situation gets really bad and people get hurt, Natsu snaps at that guild member for their irresponsible behavior.

Ash could be a likely supporting character. He's been friends with both May and Drew in the Pokemon series.

In a 'naruto finally snaps fanfic', Naruto is the main focus, but characters like Kakashi would be involved. Kakashi has been Naruto's teacher and mentor, so he would be affected by Naruto's change.

Gaara has his own connection with Naruto, and Naruto's snapping would have an impact on their relationship and the balance between villages.
