Mr name man, name me a name

Oh, this is a handy tread!

English is not my mothertongue and now I have a name in mind, but I have no idea if this is 'good' English.
I don't have the import image yet, but she will be white (ancient Quirl) with a pink blaze, pink socks with white spots in it and a pink blanket with white spots. Pink manes and a pink tail.
She hates it that everybody calls her cute so I want to name her: Avenger for Cuteness. Or must it be: Avenger of Cuteness ??
Please help me 

I think Of cuteness sounds more correct, but for a names sake I think for cuteness works too.
