Original Description:
 
Greybow Trash is a freelance guitarist and Rainbow Dash’s opponent.
 
 
Greybow Trash has a rude attitude and is more violent than other characters. Her catchphrases are “Rave it to Trashie!” and “My guitar is in your face!”.
 
 
Her appearance is similar to Rainbow Dash’s, with the only exceptions being that she has a monochromatic palette and plays guitar right-hoofed (contrasting Rainbow Dash, who plays left-hoofed). She also has a black shirt with a storm cloud on it, grey pants and black shoes to match her rock’n’roll personality.
