One is a light blue Arabic numeral 1. One's color is similar to that of Four's, albeit slightly paler. She is armless, unlike the other algebralians. On some occasions, One’s eyes appear slimmer and more tilted. One likes to “help people out”, such as when she gave Fanny a new mouth and gave Ice Cube new legs. However, her full intentions are still unknown, but it’s suggested that she wants to get ahold of Two’s Power some way or another; saying she has power, just not enough.
