Fiddleford Mcgucket from my latest (and favorite) Brony Ford AU

Basically, Ford Pines from Gravity Falls discovers MLP and binge watches the entire series in record time. He then creates an AU where the cast of GF and himself are ponies, and Ford is the pupil of Queen Twilight Sparkle. This is Fiddleford, Ford's friend from Twilight's School of Friendship. His cutie mark is a circuit board shaped like a hand giving the finger.
