It's possible that the main characters are a group of misfit kids. They don't fit in in the normal world, but in the world of the Rainbow Kids Story, they find their place. There could be a shy kid, a noisy kid, a kind - hearted kid, and so on. Each of them brings something unique to the story as they explore the mystery of the rainbow.
I don't really know who the main characters are without more information. But it could be characters named after the colors of the rainbow, like Red, Blue, Green etc.
In the Rainbow Friends Story, the Rainbow Friends are the prominent characters. Each Rainbow Friend has its own distinct look and behavior. For example, one might be really tall and blue, another could be small and pink. Besides them, there are usually characters like a group of kids or a lost traveler who end up in the area where the Rainbow Friends are. These human - like characters then have to deal with the Rainbow Friends, whether it's trying to escape from them or understand them better.
It depends on the specific version of the story. Sometimes it could be a young and adventurous boy who is intrigued by the legend of the pot of gold at the end of the rainbow.
Maybe there is a young protagonist who is on a quest. This character could be deeply affected by the sight of a rainbow at a crucial moment in their life and that sets them on a path of adventure or self - improvement. There could also be an older character who serves as a guide or mentor, and their relationship with the younger character is intertwined with the rainbow symbolism.
The most important character is surely the rainbow fish. It's the one whose journey we follow throughout the story. And then there are the other fish in the sea. These other fish play a crucial role too. They are the ones with whom the rainbow fish has to learn to interact, share, and build relationships. Without these other fish, the rainbow fish would not have had the opportunity to grow and change as it does in the story.
The main character is the Rainbow Fish. There is also a little blue fish which plays an important role in the story as it is the one that first asks the Rainbow Fish for a scale.
I'm not entirely sure without reading it, but they might be related to the main characters from 'Rainbow Days'. It could be friends, family members, or even characters who had minor roles in the original but get more spotlight in the side story.
The main characters are the Rainbow Friends themselves. Each of them has a distinct look and role in the story.
Since I'm not familiar with this story, it's difficult to name the main characters accurately. But given the title, the girl with the rainbow skin is surely a main character. There could be a villain or a mentor figure in the story. Maybe there's a character who at first is afraid of the girl because of her strange skin but later becomes her friend, which would also be an important character in the plot.
The Rainbow Fish is the central character in the story. It's a beautiful fish with those remarkable scales. Besides the Rainbow Fish, there are other fish in the ocean that play important roles. Some are the ones that the Rainbow Fish first refuses to share with, and they represent those who are in need or desirous of the Rainbow Fish's special scales. There may also be some wise old fish or friendly fish that nudge the Rainbow Fish towards the realization of sharing and friendship.
