One Steve Limit: The new character Harper is not the first character on the show with that name. "iCarly Saves TV" had a character named Harper who performed a song on Carly's web show. Both characters are even portrayed by black actors, with Leon Thomas III, the Harper on the original, going on to play main character Andre in Victorious.
The real world isn’t a story with characters that could potentially make it worse. We also ask that you wait 6 months after a character is introduced or becomes hated before adding a character as an entry, to cut down on kneejerk reactions. Although this applies to individual characters, as a YMMV item, it should not be listed on character pages.
