Cola's story starts 22 years before she was actually born oddly enough... She wasn't born in this universe.. she was born in a place with humans. She wasn't born as a female.. actually male to say it as she lived her life. Finding love in the oddest places. When they turned 22, they ended up dying from a car crash long story short, The universe decided to give them another life. We don't dwell on what she did or didn't to as it isn't relevant to her actual story, the one that matters.
They were reincarnated as a filly to a couple., who loved her very much. Though they were put off by the things Cola drew as she had drawn weird carrages on wheels and what looked like mechanical Pegasus's. When questioned she said weird words which they didn't understand. So she was put off as having a over interactive imagination. A few years later as a 10 year old filly, she had grown a bit but not much. Her grades were slightly average as she was known for just talking about weird things during class, getting confused for what seemed like other worldly history such as something about towers falling and wars that never happened. This caused Cola's grade to go down as she didn't understand why.. she was telling them the correct answers wasn't she..? Maybe she was just.. special, yea that's it! Special! .. the way they said it though.. didn't sound like she was actually special.. just.. challenged. Like she was just an udder disappointment of a child to her parents.
This had caused Cola to go into depression, only finding friends with her imaginary friends. One's that didn't judge her as the fillies and colts cast her out of sight. Only to be seen in photos that no ever looked over.. Only being that one filly that no one would care if she didn't show up one day and never came back. She just wanted somebody.. somebody to call a friend.. of course this never happened.
A year later, the day before her 14th birthday. She was rushed to the Baltimare Emergency room as her parents came home to find their child spazzing on the floor with a whole bunch of bottles that were empty which once contained pills. Luckily.. the doctors could remove them from her system and properly treat her as she was now in a comatose like state. A 75 percent of surviving which was rather high, however she ended up being in a coma for a year as she woke up the day before her 15 birthday.
She was never the same after that as she just always stayed quiet.. never wanting to be by anypony. She hated them.. she hated them all.. She hated them for disreguarding her rights as a pony.. she hated them for never wanting to encourage her drawings she made. Even when she did good on anything.. they just.. ignored her.. One day, she packed her saddle bags and ran. She ran as fast as one could possibly run. Hell she didn't know where she was running she just knew she was gonna be anywhere but there.. She ended up making her way to Ponyville after ignoring the everfree forest completely from anger. She ended up on the ponyville orphanage where she passed out on. The caretaker, Rainbow Sunshine ended up carrying her in and setting her up a room. She never asked where Cola was from when she came to or where she had been. She just knew she was badly hurt.. not physically but mentally.
A few months later Cola had began accustomed to her life at the orphanage, Rainbow was practically like her actual mother.. she was caring and nice.. 3 months later Rainbow had adopted Cola as she lived with Rainbow. She also had found out that Rainbow had a husband in which showered Cola with love and affection as Cola finally finished high school and went to college where she learned chemistry.
