The main characters are likely the naga and the dragon.
I'm not sure about the specific 'Dark Naga Dragon Story' as it could be a very unique or less - known story. It might involve a dark - themed adventure with a naga (a half - snake, half - human or other creature in mythology) and a dragon. Maybe they are enemies at first and then have to team up for some greater purpose, like saving their world from a dark force.
The main character is likely the dark dragon itself. There may also be a hero who tries to defeat or tame the dragon.
Since I don't know the story in detail, it's hard to say for sure. But I assume the dragon would be one of the main characters. There might also be some other characters like a wizard or a fairy who either helps or hinders the dragon in dealing with the bumps in the dark.
I don't know for sure as I'm not aware of the specific 'Dark Angel Dragon Story'. But likely, there would be the dark angel and the dragon as main characters.
Since we don't have the full story, it's hard to say for sure. But most likely, the dragon itself is a main character. There might also be a hero or a villain. If the story is about someone trying to take the dark stone from the dragon, that person could be a main villain. And if there's someone trying to protect the dragon or the stone, that could be a hero.
Since I don't know the exact 'dark diamond dragon story', it could be the dragon itself as a main character. Maybe there's also a wizard who is trying to control the dragon or use the power of the dark diamond.
Since I don't know the exact story, I can't say for sure. But there could be the dragon itself as a main character. Maybe there's a wizard or a brave knight who crosses paths with the dragon and the dark crystal.
The dragon is surely one of the main characters. There might be a sidekick character, like a small magical creature that accompanies the dragon on its journey to find the light in the dark. And perhaps there's an antagonist, a dark force that tries to keep the dragon in the darkness and opposes the 'light' that the dragon is seeking.
I don't know who the main characters are as I haven't read this story.
Well, obviously, the dark dragon is likely to be a main character. It could be a powerful and mysterious being with its own goals and desires.
