All right, you got me... I actually made a Sonic OC in elementary school, before I knew that making OCs was actually a widespread hobby for most people online. His name was Hurricane the Wolf and, regrettably,I gave him three tails for the sake of one-upping a certain fox. Actually, his "design" was pretty much just a black-and-grey version of Tails, but with a taller and more lanky figure.
I also remember spending a lot of time on developing his powers. He could start a small hurricane at will, affecting anything in a mile-wide radius, use his tails to fly (although I shouldn't have to tell you that), and make small earthquakes by launching "underground hurricanes." One distinct ability that he used was that he could summon these hurricane discs that he'd throw as weapons. Since Tron: Legacy had just come out at the time, I basically just wanted to give my character the ability to throw around those light discs.
