Goth was raised by Error when his father (Geno) "disappeared". Error, being the destroyer of worlds, raised Goth with love and care to be like him and destroy universes. On the opposite side of the spectrum is Palette raised by a guy called Ink, The creator and protector of universes who, much like Error, raised Palette to become a creator like him.
Or:
Ink sucks and Palettes gay for mysterious destructive men.
