In my times of Sonic Fandom, of all of the old Sonic OCs I had, none of them were hedgehogs. The reason behind this is because I simply didn't want to have a hedgehog OC. Seriously, there are too many hedgehog characters and I didn't want to follow that trend. Instead, my Sonic OCs were different animals, mostly felines to be exact.
Now that I developed my own universe of OCs, I'm showing you big differences between a mobian hedgehog and an anthro hedgehog in my style.
