One is an integer algebralian who goes by she/they pronouns and lives on the Equation Plains/Grasslands along with all the other 0-10 integers. She is mentally broken and has anger issues. She’s been left out and alone for most of her life, being pushed away by the other integers though she was kinda close with Three for a little bit. The meteor known as the Yoylite crashed on their planet and One found it. It gave her powers along with all the other algebraliens once Three showed it to them.
