Eris seems generally tired, bored, and grumpy, as evident from the dark aura around her eyes. Despite making just one appearance, she already displays pessimistic traits. During her encounter with Saturn and Uranus, she seemed disinterested and didn't bother to help them more than giving out vague directions as to where Neptune went. Eris is always confident, as shown in Dungeons and Dwarf Planets, as she confronts Lord Venus in the game, while Pluto in nervous and unable to response to him.
