Backstory...huh.
The only backstory I have for Slinger Tori is that he was conceived by the most fatal flaw of a rooster not keeping it in his pants to a cross-gender salamander.
Oh, and that his father abuses him by starving him, only to leave out a sandwich to which Slinger's father uses as leverage and an excuse to rape beat his son.
And then at some point he made another mistake with a cross-gender slug dragon and then came his younger sister Nitro Glycerin.
