Seems there is a 5th mystery character in Sonic Rivals. Oh, how the anxiety builds up when we hear of mystery characters. We'd love for the creators to just blurt out who they really are, right? Well, maybe not! It's also fun and exciting when you finally find out who they are.

Well now, a photo taken at the Penny Arcade Expo displays the Sonic Rivals character select screen. On that screen, you can see there is a box with a question mark that has the mystery character waiting to be unlocked.

Backbone Entertainment, the developer of the PSP title Sonic Rivals was present at the Penny Arcade Expo. However, they did not reveal who that mystery character was.

Guess we'll just have to wait and see, huh?
