Spark Plug never had it easy in life. Sure, he was born to two loving parents and lived in a quaint little town, but lady luck decided to throw him a curve ball.
He has no magic.
Normally such a thing would devastate the normal pony, but Spark couldn't care less. Besides, why would he need magic when he can just invent devices that can easily replicate it?
With the story being in constant development, I'll add characters and tags when needed.
