Made this in Adobe Illustrator. Might do some doodles featuring him later.
My OC Pony Hay-Wire!
A Bright, Brilliant Unicorn, with her own plethora of flaws. Dubbed Hay-Wire but her friends and family, she was always a bit off. Friends with Ditzy Doo when she was a filly, they grew up together, until an accident near the outskirts of the Everfree Forest, she and Ditzy were attacked. Ditzy was able to fly off safely, and alert the town, but Hay-wire was not so lucky. Loosing a leg and an eye in the attack, she was brought to Ponyville Hospital, where even magic could not completely re-create her leg.
During her long stay in the Hospital, she was unable to get around as much as she liked, or go on adventures with Ditzy. However, she began to read to pass the time, and eventually began to read everything she could find. Once she was released, she began to visit Golden Oaks Library, and noticed a few old tombs mentioned that a unicorn could use magic to power certain 'Metal Ponies' temporarily to perform basic functions, but the technology was scrapped, since the output was not worth the magical effort and time needed.
However, it got Hay-Wire thinking. She was then able to piece together a basic replacement for her leg, earning her cutie mark, which is a gear. However, she was never able to create a perfectly working leg. Happy that she now had four legs, she scrapped the idea of improving it. However, her eye was next. Years and Years of research passed, and sadly, Ditzy and her began to separate. Many sleepless nights later, and some study of the crystals that were brought back from the crystal empire once it was back, allowed her to create the MARK I Eyepiece. She was finally a full Unicorn again.
In order to prevent this character from becoming a Mary-Sue style character, Hay-Wire has had to make sacrifices. She cannot cast normal magic without loosing power to both her eye and leg, and since they run off of her own background magic, she has to be careful. Not being an Earth Pony means she cannot do the work normal Earth ponies do, such as grow food, and lacks the connection to nature. All she does not is attempts to re-create her bionic leg and eye, and perfect them, giving them a separate power source, to help Unicorns, Earth Ponies, and Pegasi; and work towards theoretical magical research, being unable to cast herself.
