She is a nervous and especially clumsy pony, but she seems resilient as she was determined to become a good flier despite several failed attempts.
Fifi is a pastel blue Pegasus with iris-colored hooves and bright lilac eyes. Her mane, tail, and flight feathers are light yellow. Her mane is wavy and tied in a ponytail with a light green tie. She wears a pink visor and bag. Her Cutie Mark is two yellow shooting stars with trails that match the color of her hooves.
Her color scheme, personality and occupation are comparable to Derpy Hooves in G4.
