PPG,RRB,PPKG,PPGZ, and RRBZ

PPG = Powerpuff Girls
RRB = Rowdyruff Boys
PPKG = Powerpunk Girls
PPGZ = Powerpuff Girls Z
RRBZ = Rowdyruff Boys Z

I would do PPKGZ for Powerpunk Girls Z, but I doubt they'll be in the anime version.

I am violently addicted to PPG related stuff right now, and I dragged my sister into it.

MWAHAHA METH!

Oh yeah, PPKG are comic-only characters from the PPG comic. I did research on them!

And Bunny was a one episode character (Twisted Sister), and people are saying that she might appear in the anime. Lets hope.
