Sonic the hedgehog, a blue hedgehog that stood on two legs was speeding through the fields of Mobius, enjoying himself immensely as he ran.  Despite the exercise, he was rather chubby and short.  But this was to be expected, since he was only around five years old.  Despite this, he was faster than anyone he knew.

During his run, a ball of light, like a meteor, was heading right for him, but instead of plowing into him at deadly speeds,the light turned into a strange creature and Sonic was bowled over, with the creature on top of him.  It looked like a pony, but it had wings, was blue, and its mane and tail was a rainbow of colors.  On its flank was a cloud with a rainbow lightning bolt shooting out.  Instead of crying from the impact, the filly was laughing.

Gently pushing the filly off of him, Sonic got up and looked over himself and her for injuries.  Finding none, he smiled.  "That was a close one.  I'm glad you're okay, though.  Do you have a name?"

The filly looked up at him with wide eyes before smiling.  "Rai'bow Dash!"  She exclaimed in excitement.  Sonic carefully picked Rainbow up.

"Rainbow Dash, huh?  Come on, I want to introduce you to my friends."  With that said, Sonic sped off to Knothole.

Over the years, Sonic and Rainbow played and grew up together, getting into a lot of trouble.  That is, until one day, Dr. Eggman attacked.

It was a day like any other, but suddenly, whole cities were taken over by SWATBots and other Egg robots, and the inhabitants mysteriously disappeared.  Sonic and Rainbow decided to investigate, and discovered that Eggman was using a machine to turn the Mobians into robots and using them to attack other cities.  With this intel, Sonic and Rainbow returned to Knothole to inform Sally and form a plan of attack.

It was decided that they'd do their best to return the citizens to normal.  Sonic was tasked with distracting Eggman while Rainbow was tasked with gathering the Mobians-turned-robots.  Sally would operate the controls while Eggman was distracted.  If this worked, everyone would be freed.  With this in mind, the group split up to do their tasks.

It took several days, and many near-misses, but they eventually managed to complete the mission.  Once everyone was back oi normal, Rainbow and Sonic destroyed the Roboticizer, so it couldn't be used by anyone else, causing Eggman to flee.  Little did Sonic and Rainbow know, this would only be the first in many adventures.
