(W) Sam Humphries (A) John Timms & Various (CA) Amanda Conner. In a special anniversary story* "Harley Saves the Universe!" no kidding! While reading a mysterious Harley Quinn comic book* H.Q. accidentally breaks all of reality. And you know the saying: if you break it* you bought it! Now it's up to Harley to travel through both time and space to fix all the continuity errors she created. Luckily* she'll have a little help* 'cuz riding shotgun is none other than special guest star Jonni DC* Continuity Cop! Good thing* too* because if Harley fails* it means her own mom will be lost forever. Gulp! That doesn't sound very funny!
