Emma is Peyton's bully (a different Peyton to the ZPAN+).

She has not only bullied Peyton, but revealed personal things about her, hacked her, tried to frame Peyton(with absolute horrible photoshop), steal her works and ruin her life.
Her main goal before was revenge as Peyton had rejected her. Now its to replace and erase Peyton FOREVER.

Her old account was @hellokittygurl

Now she has two accounts, both of them stealing Peyton's works.
