Nothing - also known as Helios - is the embodiment of bad thoughts/feelings. He has a sister named Harmonia, who also goes by Selene, but prefers the first name. He can be pretty blunt at times, but will also start over-explaining and sugarcoating stuff the second he thinks he did something wrong. He’s very empathetic, as he can feel the negative emotions of others, and literally feeds on them. He doesn't want others to worry about him, however. He prefers to help others.
