File:Powerpuff girls oc rebecca utonium by monstarzgirl-dabh2r9.jpg

For my Powerpuff Girls fanfic, "Rebecca Utonium: Beauty and Brains", here is my OC Rebecca Utonium. She is the niece of Professor Utonium and is the Powerpuffs' cousin; she is like a big sister figure to the Girls. She is also Mojo Jojo's match and girlfriend. The two didn't like each other at first and always butted heads (mostly due to Mojo being the Powerpuff Girls' arch nemesis and Rebecca being a Utonium/in league with the Powerpuffs), but they slowly get to know each other and fall in love when Mojo makes a deal with HIM in order to win Rebecca's heart by being taller and when Mojo begins to develop mixed feelings by writing secret admirer letters to her.
