Roko Smith:  
She was hated in her small tribal village due to being possed by a demon, then was banished and sold into slavery by the chief of the village, her grand father. She managed to run away a few years later and began to live off the land.
 
Slowly becoming happier after meeting and making friends and improving her life, she decided to cut her hair off and dye the stripe yellow to forget the past(she kept her tribal stripes because she loves them :P).
 
When she was older she met a pony named Hell Berry, who completed her life. She now lives happily with 3 fillies, hoping her past does not come back to haunt her and her family.
