I have made several sonic OCs before this guy but they were all for trolling :P Though i fairly sure Stalker is my first sonic OC that has some back story to it, even though it started off as a throw away character with a gimmick

Stalker started off as a joke character that would hide and live out of Amy Rose's closet. Using his skills to stay hidden while taking pictures of her.

Later his backstory got filled out more to to be more than a background character as well as give Fileur a reason to be a pain also having a connection to Flop as well. But the base story is he's an EX-G.U.N. member who use to be an infiltrator/ spy. He went MIA after tripping over Flop. Currently working as a freelancer reporter/ photographer who goes into dangerous situations. I like to think of him as the guy who get's those snap shots of the heroes and robotnik during those crisis.
