7-year-old girl

"I don't have what it takes. I don't think I can do all this adventuring on my own. But I'm not going to give up. I need to keep trying harder and harder until I succeed!"

- Marine the Raccoon

Marine the Raccoon (マリン ・ザ ・ラクーン) is a fictional character from the Sonic the Hedgehog series who first appeared in Sonic Rush Adventure. She is an anthropomorphic seven-year-old raccoon originating from an alternate dimension who lives on Southern Island.

History
Seven years prior to Sonic Rush Adventure, Marine was born on the isolated Southern Island, a lone island located in the middle of the vast ocean. Growing up, Marine was kept company by the Coconut Crew and her own wild imagination about travels and adventures. As she grew older, however, Marine began to feel trapped on her own island as her home did not have much to satisfy her thirst for adventures and new experiences. Marine would therefore spend her days gazing upon the vast ocean surrounding her island, wondering what kinds of places and adventures her world had in store (especially the nearby Plant Kingdom) while dreaming of becoming the captain of her own ship so that she could sail around the world. By the time Marine was seven years old, she could no longer stand being cooped up on Southern Island and began making numerous attempts to make her own ship.

In Sonic Rush Adventure, Marine wrecks her ship, the SS Marine, by forgetting to install the brakes. When Sonic the Hedgehog and Miles "Tails" Prower crashes on Southern island, they decide to help her repair her ship, where Tails builds the ships and Sonic goes to find the materials for the ship. Unfortunately, Marine and her new-found friends find themselves confronted by a dangerous menace: the pirate Captain Whisker.

Personality
In terms of personality, Marine is rather dimwitted and so often acts before she thinks. She is relatively bossy and attention-seeking, and characters occasionally find her annoying, but she has many koala friends who are pleased to help Sonic and his companions. Also, due to her age and childish personality, she sometimes has trouble saying some words that Tails can say easily like "hovercraft" and "submarine". Interestingly enough, according to Sonic Channel, Marine is described as a "neat freak". She speaks with an exaggerated Australian accent, using Australian slang words such as 'strewth', 'bonza' and 'cobber' and adding the word 'mate' to the end of her sentences.

She is very afraid of ghosts and been so since very young, but hides this from Sonic and his friends. She is also very focused about proving herself and her image, and will often try to act tough and in control in front of others even when she herself is skeptical or anxious, as she wants to prove her worth as a captain. After the events of Sonic Rush Adventure, she receives some character development after her actions had endangered herself and her friends, and she becomes more down to earth, while still maintaining her passion to become a captain. She is however still quite reckless and gets into trouble.

Archie Comics
Marine also appears in the Sonic the Hedgehog comic adaptation of Sonic Rush Adventure. She later reappeared in first issue of Sonic Universe, where she and Blaze rescue Shadow the Hedgehog from the ocean, team up with him to battle an incarnation of Metal Sonic, and later help him return to his home dimension. Her next major appearance would be during the Pirate Plunder Panic arc, where she and Blaze would team up with Blaze's friends from Mobius, Amy Rose and Cream the Rabbit. Having formed into Team Rose, the companions did battle with the evil Captain Metal and his crew of pirates.

Powers and abilities
Marine has somewhat impressive mechanical skills as she has successfully made small water vehicles on her own, but only after many tries. By the time she met Sonic and Tails, she had gotten everything right except forgetting to install the brakes. Eventually though, she grew enough in skills to build a complete and fully operational water bike, the SS Super-Marine, on her own.

At the end of Sonic Rush Adventure, Marine is shown to have some sort of special power, as seen in Deep Core where she is seen shooting a light green ball of energy from her fist. The fact that the Egg Wizard was knocked around a little when Marine shot this attack suggests that there is some great power to this ability.

Trivia

 * It can be assumed that Marine is very ticklish, as when Captain Whisker threatens to use a tickling device to torture her, she begs for "Anything but that!".
 * Marine's pigtails are shaped like boomerangs, relating to her Australian accent.
 * Marine is afraid of ghosts, as seen when she acted very nervous in the Haunted Ship stage and by Kylok when they arrived at his island.
 * Marine may have a hobby or skill for surfing as a Sonic Channel calendar depicts her holding a surfboard.
 * Marine has also revealed that she is aware that she's not a real captain but merely pretending. As shown in Sonic Rush Adventure, after the Ghost Titan was defeated and everyone heads back to Southern Island, Marine says that "One day, I'll become a captain for real!".
 * Though not shown in Sonic Colors, in the DS version Tails asks Blaze, "So, how is Marine?", to which Blaze answers, "Heh, same as ever.", causing Sonic to assume, "Getting into trouble, then." This implies that Blaze has encountered Marine at least once since Sonic Rush Adventure.
 * Although she isn't playable, a costume of her is available for purchase in Mario & Sonic at the London 2012 Olympic Games.
 * Based on the stats of her costume, Marine may be a speed-type character within the Sonic series.
 * Marine's name is featured on the Chao in Space 2 Perfect: Chaos Strikes Back billboard in Sonic Generations.
 * Sticks the Badger bears a heavy resemblance to Marine. As a result, many fans initially thought Marine was reincarnated in Sonic Boom as Sticks the Badger before it was confirmed that Sticks is a new character.
