Stain is a very neutral character since he was born between Nightmare's and Ink's power. Like Ink, Stain is afraid of dark and confined spaces also known as claustrophobia. Negativity makes Stain's strength grow since Stain's soul is a negative apple. Stain isolated himself in a random portal since he questions whether or not he should be good or bad. Stain isn't very good at making friends, but he manages to make a few friends and is often confused why he scares off almost everybody.
