One

One appears to be nonchalant, calm and seemingly helpful, but is very manipulative and malicious under the surface. She constantly observes the contestants to learn their vulnerabilities, which she uses to blackmail them into signing her deals, often for rewards she may or may not actually give.

Appearance: One is a light blue Arabic numeral one (1), being based off the design of the "1" with a lower serif (𝟷), likely taken from the original Minesweeper. The upper and lower serifs of the "𝟷" are misaligned, the former more far off to the left. Unlike almost all well-known algebraliens, One doesn't have any arms. Sometimes, One's eyes appear to protrude outside her body, and on some occasions, they appear slimmer and more tilted, including when she is enraged. She has a massive butt to grind people with or flatten them with, depending on their size.
