Gender: Genderless (Male identity) Personality: Energetic and slightly mischievous. Characteristics: An Algebralien in the shape of the number 0. Unlike other Algebraliens, there are five of them rather than one. Unlike the others who roam freely, they play a role similar to the manager of the Equation Playground. Also, specifically in the Algebralien universe, they possess a very broken ability: they can use ÷ to completely erase an Algebralien's existence. Likes: Guest Dislikes: Wolf Has a lot of embarrassing past moments. Cute. One of the ones who always tries to monopolize your side. Only Zero can use that ability, and they only use it at the most critical moments (not recklessly).
