The Legend of Maka Albarn
LOTM: The New Multi-Universal War
The best way to say their relationship is their like Sonic and Tails. Fluttershy being Tails the little kid who got bullied for being different and Rainbow Dash being Sonic the best friend who was the only person who stood up for them. They have known each other when they were just fillies. Rainbow Dash is always there for Fluttershy and she's there for her as we have seen in "Hurricane Fluttershy".
The 2 of them first met in The Grand Summer Season Trek. They work together for a short time but they became close friends in that time. Later they reunited fighting Ares and Zeus. In that time Rainbow Dash has become one of Knuckles closest and most trusted friend.
Rainbow Dash tends to get seriously competitive with Tucker at most times, but have a good friendship like Pinkie Pie does with Caboose.
The villain she hates the most. After what Mechuckles did to his son, Knuckles, in the past since Knuckles was a child and tortures him in TROM: BOTSS, Rainbow Dash is PISSED for what Mechuckles did and goes after him for all the shit he did to his son.
