Marina is a very bright and bubbly girl. She's a gentle spirit and quite the comedian. Her favorite catchphrase is "Hip-hop & Pop" and she usually rhymes it to make a sentence (i.e. "hip hop and pop, Shout's legs just won't stop"). Her favorite colors are turquoise and purple. She wears a turquoise dress with a purple belt, Converse sneakers, and dark purple leggings beneath the dress. In seasons 1 & 2, she wears a dress with purple cuffs, her leggings go below her knees, her sneakers are purple, and she wears a pink bracelet on her left wrist. Starting with season 3, she wears a dress that's similar to Sgt Pepper. She wears capri leggings, and she has rose pink Converse sneakers with turquoise socks, and she wears a purple bracelet on her left wrist. The buckle on her belt has her drum symbol. She also wears a blue flower necklace and her hair is auburn red. When she is in her pajamas, she wears purple with flower designs. She has duck slippers that quack but only in "Quack Shoes" and "Back To School".
Marina usually comes up with an idea to solve the problem the Fresh Beats are having. She usually takes the lead to jump start the band's ideas as well. Marina also has a habit of agreeing with all of Twist's crazy ideas, saying "You know, that would be cool or..." only to give a more simple, realistic explanation afterward. There have been exceptions where she agrees with him, though, and sometimes she thinks of random ideas that are much easier than Twist's. Marina can be very optimistic as shown in Dance-A-Thon. When she accidentally dropped an ice cube in her dress, she was running and spinning so much that she got eliminated from the dance-a-thon; but she was very optimistic about it as she'd finally gotten the ice cube out of her dress. Being the drummer of the band, Marina is very proud of her skills and very attached to her drums. Though she is quick to forgive anyone who breaks her drums, as they have been broken more then once, she is upset when they are. She also cares for any set of drums as seen in "Stick Together" where she makes the band cover a set of drums in the music room before wallpapering. She also owns two sets; one being her normal set and the other being made up of items, or found sounds, found in town in "Stomp The House". Marina owns different kinds of drums; in Drum Party, everybody in town gave her every kind of drum in Reed's music store for her birthday. There are so many different drums she has: her own drum set, her found-sound drum set, a jembe drum, a conga drum, bongo drums, a steel drum, a timpany drum, etc!Other then drumming Marina loves to dance and is, unknowingly, a very talented Hula dancer. She loves to sing, dance, and dress up, especially if its her favorite party dress she gets to wear. She likes decorating and even got the moon for the Night Time Festival in "Glow For It". All in all she cares deeply for the rest of her friends and would do anything to help them. She is the owner of a beautiful pair of sparkly dancing shoes. She wore these shoes in "The Wizard of Song" when Glinda the Good Witch transferred them to her feet. After waking up from this dream, Marina was unaware that she was still wearing her shoes until Kiki complimented them and it was shown she was still wearing the shoes!
As revealed in Rock Star, Marina had a habit of trying to cheat when it came to playing Rock Star. She loved the Rock Star jacket so much she wanted to wear it, but in order to win, she had to play a hard musical riff. The hardest riff in the game is yellow, playing "Twinkle Twinkle, Little Star" quickly. To her annoyance, she always lands on yellow, and to get out of playing the yellow riff, she would pretend she landed on another color. She learned the hard way to play by the rules. When Marina moved her game piece to the black & white swirl space, she and her bandmates got beamed into the Rock Star game world, and they couldn't get out. That's when Marina promised to play by the rules. Kiki, Twist, Shout, Harper, and The Junior Beats helped her win the game by using all of their legs to play her hard riff. Marina continued to play by the rules and hold back her competitiveness. She is possibly the owner of the board game that the band was playing with.
Marina is very sneaky and tricky as shown in Drum Party and some episodes in season 3. So be careful if you distract her!
Marina isn't very good calming down when trouble arises as shown in Ghost Band. So her bandmates help her calm down when she panics. For example, when the Fresh Beats got locked in jail by The Ghost Band, Marina suggested they remain calm, but then she panicked, and Kiki and Twist calmed her down before she had a meltdown. This may show that sometimes she can be a bit of a scaredy-cat.
In the Season 2 episode, "Band in a Jam", Marina as a child is played by Mackenzie Brooke Smith. It was revealed that she was a new student when she met her bandmates. She is also portrayed as a baby in this episode.
Marina was the Dorothy character in The Wizard of Song. When she was swept up in a tornado, she landed in Oz. She met Glinda the Good Witch and The Juniorkins. Glinda gave her the beautiful sparkly shoes. Marina was very afraid of the Bad Witch who attempted to kidnap her and steal her shoes. Marina overcame her fear of the Bad Witch when she (the Bad Witch) confessed that she wanted to be a better dancer.On her way to the Emerald City, Marina met Scarecrow, Tin Woman, and Cowardly Lion whose faces were very familiar. Marina's scarecrow was Twist! Marina was very sad to leave her new friends, but it could be possible that she'd think she's with them since they look and talk like her bandmates.
In the dream, Marina had her hair in pigtails. Behind her ears were blue ribbons that tie up her pigtails. She wore a Dorothy dress that was in a blue and white plaid pattern. The dress had buttons just like her usual everyday dress. With this dress, she wore pink flats when she found herself in Oz. When Marina had the pink flats, her feet were bare. When Glinda gave her the sparkly shoes, she was wearing socks.
