StoryOne day Error needed a new rival for Ink, so he got some Ink from Nightmare and PaperJam. Then, he forced Science!Sans to make a creature from it. Black Ink was born.
He's a huge fourth wall breaker and is really smart. He hates attacking first or at all, and feasts from Negative energy.
He wears a black robe with white spots and has a white bandana with colorless eyes.
Black is a brooding loner, to put it bluntly. He is rarely seen with others for an extended period of time and usually distances himself from essentially everyone. He is usually soft-spoken, silent and doesn't speak much, but he always knows exactly what to say in combat.
