Perhaps there is also a villain in the fanfiction. This villain could be after the power of the man made of lasers, either to use it for evil purposes or to eliminate the man made of lasers out of fear or jealousy.
Obviously, the man made of lasers is one of the main characters. He would be at the center of the story, driving the plot with his actions and abilities.
One interesting idea could be the unique powers the man made of lasers might possess. For example, he could have the ability to refract light in ways that create illusions or even manipulate energy on a different level compared to normal characters. Maybe he can use his laser - like body to communicate through light signals in a secret code.
A vampire and a werewolf who are both outcasts in their respective supernatural communities. They meet in a place that is like a hell on earth, a desolate and cursed land. They have to work together to survive against hunters and other threats, making them a 'match made in hell' in the sense that their species are natural enemies.
Obviously, Harry Potter would be a main character since the title centers around him. There might also be characters like Hermione and Ron who could be reacting to Harry's new snake - like state or trying to help him understand it.
I'm not entirely sure as it depends on the specific fanfiction. But typically, it would be the two main characters from the original work around which the fanfiction is based.
Perhaps there's also a mentor - like character. This could be someone who has had past experiences with the Nightmare Man and provides guidance to the protagonist, sharing secrets about the Nightmare Man's weaknesses and the nature of his existence.
I don't know for sure since I haven't read it, but the Betting Man is likely to be a main character.
Obviously Naruto himself is the central character. His friends like Sasuke often play important roles too. Sasuke might be there to support Naruto or sometimes challenge his decisions as Hokage.
Since I haven't read it, it's hard to say for sure. But we can assume Mega Man is one of the main characters, and of course, the 'unmet man' as the title implies. There could also be other characters from the Mega Man series that are involved in the story in relation to these two.
There could be his usual supporting characters like Aunt May. In the context of the gamer fanfiction, she might play a role in his 'game - like' world, perhaps giving him advice or helping him with in - game tasks.
Naruto is often one of the main characters. He is the central figure in the Naruto universe, so it's likely he'll play a major role in any fanfiction related to it. The striper character is also a main character, as the story revolves around this unique element.
