Well, obviously the mad doctor is a main character. He could be an original character created specifically for the fanfiction. Then there could be Naruto himself, who might be involved in trying to stop the mad doctor's evil plans or, in some cases, might be seeking the doctor's help for a friend's illness.
If the fanfiction is set in a more complex plot, characters like Tsunade could also play a major role. Given her expertise in medical ninjutsu and her position as Hokage, she would be very interested in the activities of a mad doctor. She might try to either recruit him if she believes he can be reformed or imprison him if he's a threat to the village.
Sakura could also be a main character in such fanfiction. As a medical ninja herself, she might be intrigued by the mad doctor's unorthodox techniques and either try to learn from him or stop him if she thinks he's doing harm. Another character could be Kakashi. He might be assigned to keep an eye on the mad doctor's activities due to his suspicions.
Well, Naruto is obviously one of the main characters. He could be the doctor or someone related to the medical field in the fanfiction. Sakura might also be a major character as she has medical knowledge in the original Naruto series. And sometimes, characters like Kakashi could be patients or play a role in supporting Naruto's medical journey.
Well, Naruto is almost always one of the main characters. Since it's Naruto - themed fanfiction. And of course, the mad chemist is another main character. They could be a new character created specifically for the fanfiction, or it could be an existing character from the Naruto universe who has taken on the role of a mad chemist, like Orochimaru perhaps.
There might be a fanfiction where the mad doctor is actually a misunderstood character. He's trying to cure a rare disease in the Naruto world but his unorthodox methods make everyone think he's mad. For example, he might be using the chakra of demons in a way that seems evil at first but is actually for a good cause.
Since I don't know the specific fanfiction, it's hard to say. But it's likely to include the forgotten doctor, and perhaps some Naruto characters like Naruto himself, Sasuke or Sakura who might interact with the doctor in some way.
Obviously, Naruto is the central character as the title 'naruto goes mad' implies. Sasuke often plays a crucial role too. He might be the cause of Naruto's madness in some cases, like if he betrays Naruto again in a more extreme way. Sakura could also be involved, perhaps trying to bring Naruto back from his madness. And Kakashi, as Naruto's former teacher, may try to figure out what's wrong with Naruto and find a way to help him.
In 'mad scientist naruto fanfiction', Naruto is central. The mad scientist is, of course, a key figure. Sakura could be another common character. She might be involved in trying to heal Naruto if the scientist's experiments go wrong. Also, characters like Jiraiya could be in the story. Jiraiya might have some knowledge about the scientist's motives or past and help Naruto figure out how to deal with the situation.
Mad Doctor was a 173-minute film in the fashion genre. It starred Noel Fielding, Lori Papadopoulos, Kanehara, Lee Shanhao, Zhao Danjun, and others. It was directed by Jeff Zembalister and Nida Mansu. It was released in 2014 in the country/region of Iceland. The plot involved the fast shooting speed of the elites, the morale of the bandits, the Laxi Cavalry and the spearmen, etc. For example, the fast shooting speed of the elites caused half of the elite bandits to die before they even joined the battle. The Laxi Cavalry was famous for their strong mounts, endurance, and speed. The best way to deal with the cavalry was to use the spearmen.

Well, it's very likely. Naruto has a huge fan base, and so does the concept of the Mad Hatter from Alice in Wonderland. Writers often like to blend different fictional elements together. So, a fanfiction with Naruto as the Mad Hatter could be out there. It might explore Naruto's character in a whole new light, perhaps with his ninja skills combined with the quirkiness of the Mad Hatter in a strange and interesting fictional world.
The main characters are clearly Tony and Tchella. Tony is the one who is mad, and Tchella is the target of his anger in this fanfiction.
