Banished from her home town for having nasty farts, she discovered that her farts are actually superpowers, so she decides to use them for bad. She hid in Ireland where she got her accent.
Her Irish accent is a little bit thick, but most of it is pretty understandable. When she insults you, she has very creative ways of insulting you.
Also, just because farting is her superpower, doesn't mean she has a fart fetish. But if you ask her to fart on you, she may be hesitant, but she'll do it anyway
