Dark GBS has a hatred for all things. All they can see is the evil, and not the good. They are cynical and violent, often threatening death to everyone they meet. Their wrathful nature exerts an aura of anxiety, to combat Gotebooksprite's aura of calm. When the two auras meet, small electrical storms can occur.
They hate everything, including themselves. When they are not torching forests or incinerating innocents, they are insulting and berating themselves for actions they did as the true GBS. They speak with a loud, growling voice, and tends to use expletive words in their language.
