The new girl on Planet Mobius was immediately noticed the day she moved in, but she wasn't sure whether or not that was a good thing. She was a normal teenage girl, yet she felt out of place already. You see, the inhabitants of Mobius are all animals. They usually never saw humans around. And though they knew very little about humans, they did know that humans preferred to stay on their home planet, Earth. They also knew that 13 year olds, like Sierra, the new girl, weren't supposed to live without an adult. So, why the heck was she there? No one knew, but they were all very curious about this strange creature. Sierra, in turn, was very curious about this strange planet, so as soon as she finished unpacking, she set off to explore. So began her new life as a Mobian.
Sierra soaked in everything she saw and heard like a sponge. The environment was much like back at home, except the animals were much like humans. They could speak Sierra's language, and they could do everything that humans could do. The Mobians also paid close attention to the new girl, and decided that she was just as civilized as they were. And Sierra decided that the Mobians were just as civilized as she was.
Although Sierra was a very shy kid, she began making friends right away, because the Mobians could tell she was really sweet and friendly. She met a pink hedgehog named Amy, and a brown and orange badger named Sticks, both of which were about Sierra's age. Sierra had a lot in common with these two, including Amy's love of singing and painting, and Stick's love of nature and outdoor activity. Plus, all three of them had different levels of quirkiness. Amy and Sticks soon introduced Sierra to their group of friends. These were a 15 year old speedy and cool blue hedgehog named Sonic, a 16 year old ripped and peculiar red echidna named Knuckles, and an 8 year old yellow and white inventor fox named Tails. Although she had less in common with the guys, she got along with the whole group pretty well.
One thing Sierra didn't know about her new friends: they're actually a fighting force that protects Mobius from this evil robot-maker named Dr. Eggman. She discovered this one day during lunch at Meh Burger with the gang. Eggman surrounded the entire restaurant with robots. Sonic and the others started smashing up the robots, until a 500 foot tall robot came out of nowhere and trapped them in a force field. Sierra wasn't about to let this happen to her friends. She snuck up behind the giant robot and pulled it's wires apart, shutting it and the force field off. Then she helped the others to fight the robots. Eggman knew he wasn't about to win this one, so he retreated.
Sonic and the gang were so impressed, grateful, and proud of Sierra that they made her an official member of their team. They even gave her a new outfit to confirm that and to let other people know she's with them. Some of her clothing items would even help her out during missions. Amy gave her an aqua colored short sleeve dress. Sticks gave her a gold locket with a red button inside that releases smoke, in case Sierra ever needed a smoke bomb. Sonic gave her a blue watch communicator with her name on it in cyan. Knuckles gave her blue sneakers, white gloves, and cyan sports tape. And Tails gave her a blue, glittery headband with a bow, built in speakers to hear through walls, a headphone jack, and a laser. He made it himself. And so, Sierra went from oddball to hero.
