One of the most exciting aspects of Rainbow High dolls is the colourful hair. Each doll has a unique hair colour inspired by the colours of the rainbow. The dolls have long, silky hair that can be styled in a variety of ways, from braids and buns to ponytails and curls. This adds an extra element of creativity and fun to playtime. While not interacting much, Karma is shown to appreciate Bella, wanting her to come on her show and tell about her reentry to Rainbow High. Bella is shown to be quite flattered, and she mentions that she is a huge fan of Kontent With Karma. The two seem to converse regularly after this. To better categorize the characters in the series of Rainbow High, we decided to categorize them in six separate sections. Shadow High: These characters received dolls and character bios but also aren't part of the main school Rainbow High, but go to their neighboring rival school Shadow High. Like the other girls in the group, Bella is extremely talented and artistic, having won an few awards in her chosen field. Though she has no qualms about boasting her achievements, she's also a friendly and outgoing person who easily befriended her roommates and hypes them up when they need it. She's also easily excitable and somewhat impulsive, but overall a team player who works well under pressure.

She is seen very briefly sitting with Ruby and Jade watching Rainbow Vision, being seen laughing at The Assistant's cringeworthy performance. While being close and stable friends, Skyler and Jade do not interact very much, but they show a great deal of respect for each other's talents and contributions. Sunny appears near the beginning of the episode where she is thrilled to hear that Amaya has a new crush on River. Despite Amaya's shyness towards it, all of her friends team up to try to get them together, including Sunny. Main Supporting Characters: These characters are the friends of the core 6 characters; they're often included by the fans as a part of the main cast. Alongside Ruby Anderson, she is seen silently getting autographs from The Royal Three in awe before they get their fittings.

While not much has been shown, her and Skyler are shown to be good friends, bonding over their love and tastes in fashion. Bella's T-shirt in her signature outfit has a very similar design to the logo of the California Dream Barbie line of dolls. This might be an intentional nod as Barbie is heavily associated with the color pink. Having a large role, Sunny works in a special group alongside the band Rainbow Dream, feeling very excited to work with them. When they make their entrance however, they instantly begin arguing with each other, stressing her out. They try to work through this but hit a wall, with Sunny taking charge and getting everyone organized into roles. Now with the group more organized, they present their project, having put their hearts into it. The two are seen cheering in the crowd along with Sheryl and Gabriella in "Rainbow Vision Finale: Part 2" and "Rainbow Vision Finale: Part 3", so we can assume they are friends.

The dolls also have a wide range of clothing options, from casual wear to formal dresses. Each outfit is designed with attention to detail, featuring bright colours, fun patterns, and unique styles. The clothes are made to fit the dolls perfectly, so they can be easily dressed and undressed for hours Being also one of Bella's new roommates, Initially, Daria gets confused when she finds Bella in their room. However, their bond has strengthened overtime; this is showcased in websiodes, where they can be seen conversing. But, they both get along very well overall. Sunny appears as she has before hosting with Luna, where they appear to introduce Maria and then leave for most of the episode. They do appear at the end however, where she happily announces the next episode is in Malibu.Sunny is shown with the rest of girls where she finds out that she might be able to be featured in The SCENE. Being excited by this, she happily gets interviewed by Krystal. When being interviewed she talks about Hi Hi Kawaii, her show about friendship, love, joy, and real life. Despite this grand interview, it is revealed that Ruby had won and is now featured on the cover, with Poppy congratulating her.

Her original quote "I don't follow trends. I set them." was changed to "Own it! I would!" the same line she said in "The Prize at the End of the Rainbow" for unknown reasons. Ruby Anderson • Poppy Rowan • Sunny Madison • Jade Hunter • Skyler Bradshaw • Violet Willow • Amaya Raine • Avery Styles Bella Parker is a 2020-introduced and all-around character. She is a student at Rainbow High that focuses in Art Direction with a special focus on Set Design. Bella has big dreams and the vision to make them come true. She's the overachiever at Rainbow High with a timeless style that's as polished as she is. Bella was made for art direction, because it combines two of her greatest strengths - creativity and perfectionism. Bella is also a natural leader at Rainbow High, because she knows how to bring out the best in all her friends. But Bella's focus and determination sometimes go too far and occasionally push her to break the rules.Like most of her friends, Skyler was rather awkward and uncomfortable around Amaya when she first came to Rainbow High, seeing her as Bella's replacement. This opinion did change however when she learned of Amaya's impressive talents in fashion, a skill they both shared. Their relationship grew even more when they started to team up on designing outfits for their group, working together to design all of the runway outfits. Bella and Gabriella became friends when they teamed up for Radiant Week, which they won and got the opportunity to spend some time at Pacific Coast High. They're later seen cheering in the crowd along with Sheryl and Finn in "Rainbow Vision Finale: Part 2" and "Rainbow Vision Finale: Part 3". Skyler is an anglicized version of the name "Schuyler", it was presumably chosen for the "sky" within the name. Sunny is seen yet again, this time being prompted to design cheer uniforms and perform a cheer in them. She and her friends all team up to do this, with Sunny creating the cheer with Violet's help. They get frustrated until Skyler and Amaya tell everyone that the looks and cheer should be unique to every person. After this, she's seen as they all perform. Despite barely even knowing each other, Amaya and Bella have a rather complicated relationship. Amaya first learns of her after meeting her runway group, learning that she is in fact her replacement. Amaya feels guilty about this, however Bella appears rather bitter towards her. They were later seen talking in " The Eclipse - Phase One, Part Two", suggesting that they have become friends.
