Original Description:

This is a character I had dancing (or should I say prancing? eh? get it? because she’s a pony and ponies prance oh god kill me) around in my head ever since before the first season of Friendship is Magic even ended. Her name is Gadgetry; she’s an earth pony and her special talent is tinkering with and building machinery. Her cutiemark is a gear the same color as her mane. Those purple things on her foreleg are hairbands; she ties her mane back when she’s doing her thing.

She came about because A) I thought earth pony OCs were few and far between and B) because…I dunno, I just really like the black/dark blue/purple/neon cyan/yellow color scheme. :B
