Seen a lot of people draw their own interpretations of what the mane six would look like if they had more unique traits. Decided to try that myself.
Here’s my take on Rainbow Dash.
She’s compact and muscular, out of the mane six she’s the second smallest/shortest. She gets her freckles and greyish body color from her mom but most of her other traits are from her dad. The scar on her shoulder and mouth are from the episode Wonderbolt Academy, where Lightning Dust put her life at risk simply to perform some extra dangerous stunts. She’ll always have the scar as a reminder of safety and to choose friends, and wing ponies, wisely. She is married to AppleJack and Fluttershy. She mainly lives on Sweet Apple Acres, helping with the laborious chores, but both her and AJ visit Fluttershy daily for afternoon tea.
